Need how to integrate Antivirus software in IExpense

While uploading file from local machine to oracle application. Please let us know , how to integrate the same . Is the feasible in oracle application. IS there any API to call the antivirus soffware.Let us know the process to do the same. Please do the needful.

Good afternoon Djohn,
SignalExpress is a great tool for taking in voltage and current inputs, and you could easily use it to calculate B. After talking with one of the support members at Tektronix, I confirmed that the TDS 1000B should pretty muchwn be plug-and-play once you have installed the correct drivers. I wanted to make sure that when you installed LabVIEW SignalExpress that you went through the hardware installation wizard, and allowed it to auto-find and install the necessary VISA drivers. You can check this by going into your Windows device manager (Start » Control Panel » Device Manager) and making sure that your Tektronic device shows up there. Be warned, it may show up as a USB test and measurement device.
If it is there, you can right-click it and select update drivers which will auto-find the drivers and update them. Once you have this completed, if you are still having trouble I can point you to some tutorials on how to get started with SignalExpress.
Best of luck!

Hello,
I recently bought a MacBook AIr, but im not sure if i need to get some kind of antivirus sofware or not.

No, you do not. However many here install ClamXaV for that 'just in case the sky falls' happenstance.

Antivirus software for Windows 7 on Mac

I recently installed Windows 7 on my MacPro and was wondering if I need to install an antivirus software program for Windows 7? I have researched and still have not found an answer.

Do i need antivirus software if i am going to download office 365 onto my new imac?

1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
   3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
   For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, and a technological fix is not going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the scam artists. If you're smarter than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
Software of any kind is distributed via BitTorrent. or Usenet, or on a website that also distributes pirated music or movies.
Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, your browser, or anything else.
Rogue websites such as Softonic and CNET Download distribute free applications that have been packaged in a superfluous "installer."
The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
High-priced commercial software such as Photoshop is "cracked" or "free."
An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission.
Conditional or unsolicited offers from strangers
A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
You win a prize in a contest you never entered.
Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
Anything online that you would expect to pay for is "free."
Unexpected events
You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
   6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial "anti-virus" products?
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Research has shown that most successful attacks are "zero-day"—that is, previously unknown. Recognition-based malware scanners do not defend against such attacks.
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
Most importantly, a false sense of security makes you more vulnerable.
8. An anti-malware product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize by the file name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to know that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's seldom a reason to use recognition software unless an institutional policy requires it. Windows malware is so widespread that you should assume it's in every unknown email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may be useful if it satisfies an ill-informed network administrator who says you must run some kind of "anti-virus" application.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

EREC - AntiVirus Software needed?

Hi All,
I have two questions and am hoping to get some advice on. I have many years of SAP experience/knowledge, however, none specific to the eRecruit package of SAP. We are implementing this package at a client and have some questions...
1) When an internet user uploads their resume and/or files - does that resume get stored in our eRecruit portal instance at the file level as a file or as a BLOB in the database?
2) Related to question one above - we need to secure against harmful files and would like to use our existing McAfee enterprise software handle this, however, am not sure if it can handle scrubbing against these (erec files). How have you eRec installers handled this (implementing an antivirus solution)?? A casual websearch shows that McAfee has a "SAP enabled" solution and another company named "Bowbridge" also has an SAP solution. I'm unsure if any of those would solve this particular problem. Really would like the answer to be McAfee though since we already have that product inhouse and working for other enterprise apps.
Thanks much for any thoughts and suggestions,
Matt

Hello Matt,
ad 1) All files in E-Rec are technically stored in the Knowledge Warehouse (KW) and the db table for the reference is HRP5134.
When an internet user uploads their resume and/or files - does that resume get stored in our eRecruit portal instance at the file level as a file or as a BLOB in the database?
ad 2) Yes, you can use McAfee as virus scan interface for E-Recruiting files too. Do you need how to adopt it to the system (eg. transaction VSCAN) or which profiles are responsible for E-Rec?
Best regards
Nicole

I am running my first time machine backup onto a Western Digital MyBook Live. It is taking forever. Is there antivirus software running in the background or any other settings I need to change to speed it up? Also I am on a wireless network.

I am running my first time machine backup onto a Western Digital MyBook Live. It is taking forever. Is there antivirus software running in the background or any other settings I need to change to speed it up? Also I am on a wireless network.

The initial Time Machine backup can certainly take a long time over wireless. Days, possibly. It's impossible for anyone here to be able to predict how long it will take, and wireless environmental conditions can change at any time.
Is there antivirus software running in the background
Only you can determine that. If you're using third party AV software, anything is possible.
NAS devices may not be compatible with Time Machine, regardless of what their manufacturers may claim. Even after the Time Machine backup completes, your backup may be unreliable. You may not discover that until you need to rely upon the backup for some reason, and corruption can occur months or years from now.
Time Machine supports the following backup configurations:
A locally mounted volume
Time Capsule
A volume resident on a USB hard disk connected directly to a Time Capsule or current production AirPort Extreme Base Station.
That's it. Any configuration other than the above list places you in an experimental category. If your backup fails, you're on your own.

Does my macbook pro need any antivirus softwares?

Ive recently got a macbook 13inch pro laptop. I've heard that they don't need any antivirus protection programmes but the shop assistant in john lewis said did? some of the basic antivirus softwares are norton and comodo. Thanks

some of the basic antivirus softwares are norton and comodo.
Those are two of the worst examples.
There will always be threats to your information security associated with using any Internet - connected communications tool:
You can mitigate those threats by following commonsense practices
Delegating that responsibility to software is an ineffective defense
Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
... I've heard that they don't need any antivirus protection programmes
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
If you need to install software that isn't available from the Mac App Store, obtain it only from legitimate sources authorized by the software's developer.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iCloud, iTunes, or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Beware spontaneous popups: Safari menu > Preferences > Security > check "Block popup windows".
Popup windows are useful and required for some websites, but unsolicited popups are commonly used to deceive people into installing unwanted software they would never intentionally install.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever receive a popup window indicating that your Mac is infected with some ick or that you won some prize, it is 100% fraudulent. Ignore it.
The same goes for a spontaneously appearing dialog insisting that you upgrade your video player right this instant. Such popups are frequently associated with sites that promise to deliver "free" movies or other copyrighted content that is not normally "free".
The more insistent it is that you upgrade or install something, the more likely it is to be a scam. Close the window or tab and forget it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. Most of these attempts are pathetic and are easily recognized, but that hasn't stopped prominent public figures from recently succumbing to this age-old scam.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Do MacBook Pros need antivirus software?

I had installed McAfee which interfered with the AirPort Extreme wireless. Apple tech said no antivirus was needed and that Apple does not support McAfee software. Any thoughts on whether antivirus software is needed and if so whether there are programs that work with AirPort Extreme?

1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet.

Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are outside the safe harbor, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real danger comes from highly targeted "zero-day" attacks that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

Do imac need antivirus software

do OS X 10.8.4 need antivirus.I recently come across Mac Keeper antivirus software on my mac.What to do with that and how to remove it from mac

Read the comment by SDW2001 in this thread.
Remove "MacKeeper" as follows. First, back up all data.
"MacKeeper" has only one useful feature: it deletes itself.
Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.
IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
In the Finder, select
Go ▹ Applications
from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the functional components of the software will be deleted. Reboot.
Failure to remove MacKeeper will result from neglecting any one of these points:
Quit MacKeeper before dragging it to the Trash.
Don't empty the Trash after dragging the application to it. Let MacKeeper delete itself.
Don't try to drag the MacKeeper icon in the Dock to the Trash.
Here are some general suggestions. If you want your computer to be usable, don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless.
The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
The only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Never install any third-party software unless you know how to uninstall it.

How good are free antivirus software?

I actually don't run antivirus on my personal machine because it slows it down (though I do run a second opinion scan every now and then). But I agree with NattNatt education is the frontline. You can add the best antivirus protection, block local admin rights and add perimeter security devices but if the user clicks on a link or an attachment they can still infect the machine. Add good security solutions but educate your users on what to look out for and when to ask you for a second opinion.

I know that when it comes to antivirus software licensed is the way to go but I might get a pretty big tender soon. 30 laptops that needs antivirus software. This will come out quite expensive for the school especially if they need to renew every year. The only other option is the free option like avast, avg free, commodo, ms security essentials etc. How good are these free anti virus software and do they really do a good job at protecting a PC? Or will it be better for the school to buy licensed AVs? I am quite a fan of Kaspersky and AVG
