Is it necessary to install some antivirus on my MAC?

So~~ is that really necessary? some say virus' main target is win. but I just wanna check it out with you guys, please share some experience.~Thanks.

Not at this time. See:
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection

If you require anti-virus protection I recommend using ClamXav.

Is it necessary to install an antivirus software on Mac OS?

I am using Mac OS. Do I need antivirus software to protect my OS?
Thx.

I have already read your malware guide Thomas, i believe many users will find it highly informative.
Like you point out though, you have little expertise in Cyber Security.
I commend the fact that you take such time in order to contribute to the Apple community.
However, none of the information I have contributed is in any way inaccurate.
Like I said, there are good antivirus programs which have had definitions updated to detect both of the recently identified Trojans. Something Apple has yet to do for 'DevilRobber' .
I love Apple. I enjoy the fact that OSX, bsd, and Linux are inherently more secure than Windows architecture.
And I agree entirely that the majority of malware can be avoided with user education, and changing of behavior.
I wish I could agree that an antivirus application is also unnecessary, however I understand the landscape to be ceaselessly changing, as no doubt you yourself would agree.
There is simply too much money involved not to target Macintosh systems, let alone the likes of Intelligence Support Systems, and SigInt.
I will do what I can to protect my systems, and you can do as you deem necessary.
I in no way intend to do a disservice to the community, nor am I intent on arguing with other users who share my passion for Apple Computers. I wont use terms like 'stupid or oxymoron' just as I hope that other users will refrain from such. Let us agree to disagree, and encourage each other to share their opinions in the forums!

I am a new Mac user. It is necessary to install an antivirus?

I am a new Mac user. Before this, I used a PC and it was necessary to have an antivirus.
It is necessary to install an antivirus in my Mac? In this case, how can I do it?
Thanks!

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
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 take control of it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in 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 taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses 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, not machine behavior, and no technological fix alone is 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 Internet criminals. If you're better informed 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 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, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, 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. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
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
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ 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 padlock icon in the address bar 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" (AV) or "Internet security" products for the Mac, as they are all worse than useless. 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 AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its 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, commercial AV 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 may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV 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 low-level 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 AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, 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 malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
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 can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. 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.

What Additional Services Are Necessary To Install?

Hi everyone, we just recently started working with the JDeveloper application and are pretty new with all of this so sorry if this is a really 'newb' question but we are trying to plan ahead for licensing and installation purposes.
A co-worker of mine has been working with JDeveloper to write some small custom internal web apps that would pull information from our production 10g database that is on a separate server and allow users to add some information that our ERP system doesn't allow them to do via its interface. The information is pretty much just for internal reporting right now on some very specific items.
We love the app so far and are excited about the potentials of JDeveloper to tie up some loose ends that our ERP system doesn't offer us. He is able to deploy the app straight off of his Windows XP machine and users would be capable of navigating to it. However ideally we would want it hosted on a server.
I fired up a Win 2008 x64 virtual server and installed some apps he had recommended. Web Logic Server 10.3.4 and he was able to sync his JDeveloper client up with this and publish projects to it but they wouldn't start up properly. He then provided me some installation instructions from some Oracle.com documents that instructed me to do the following:
Install Oracle Web Center
Install Repository Creation Utility
Install Oracle Database software
As it all turns our first thing I had to do was install an Oracle DB. I tried the Oracle XE but then RCU gave errors that appeared to be caused by XE's lack of certain tables. I then installed the trial of 11g and RCU installed with a few bugged options. I then began the battle with Web Center (which had previously prompted me for RCU first).
As we are fighting these issues I really wanted to reach out to the community/specialists and find out if you think we actually need all/any of these things for the internal apps we are making. These apps shouldn't be 'mission critical' by any means right now and they deploy fine from my co-workers jdeveloper launch. Ideally we would like the capability to allow people to leverage their login from our production 10g server but that isn't necessary at this moment.
Any general direction or advice would be helpful. I attempted to get Oracle on the phone to point us in a direction but they passed us off to some standard sales department that was trying to sell us hardware :P

What type of technologies are used in these apps?
Does it use any WebCenter related stuff?
If the answer is yes, than you need to install WebCenter as well.

How do I completely uninstall intego net barrier? I can't install Norton Antivirus 2012 until this is off my computer

How do I completely uninstall intego net barrier? I can't install Norton Antivirus 2012 until this is off my computer. And I can not get it off my Computer. ANyone?

Intego has their own uninstaller which is the best thing to use. Otherwise, see the following. From a practical point of view you really don't need any such software on the Mac.
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, Easy Find, instead. Download Easy Find at VersionTracker or MacUpdate.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
AppZapper
Automaton
Hazel
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning
Look for them at VersionTracker or MacUpdate.

Dear Victor
The answer is it depends on your business requirement. There is a need to apply support packs regularly ( annual, 6 months) based on your maintenance schedule, this is to ensure you get legal and obligatory changes in the system.
EHP contains enhancements as well in addition to fixes to your environment. The enhancement contains new business functionality which needs to be activated as needed only.
The other area to be aware is to ensure you keep the system in supported mode by applying support packs.
Pls check the PAM(product availability matrix) for support end dates.
Also check this link for FAQs, install details from SAP.

My phone was working well. i installed some free games and after 2 days u guyz charged me $34 from my debit card. and now i can install any free apps, they keep asking to put my billing info for those. please this is urgent. i want my money back.

hello sir/madam
this is a very urgent and important question. i nedd your assinstance.
i have iphone 3g. i was working well. about 2 months earlier i bought an app of $2.99. after then every thing was okay. but last week i installed some free games and 2 days later itunes send me a reciept via email and you guyz charged me $34. now whenever i try to install free apps they want my billing info. please i need your help and want those money back.
$34 for free games , i will show u the reciept. if its not possible to get the money back i will forced to take proper action.
thank you sir /madam.

The games might be free but I think you've clicked In-App purchase which cost money. You are warned before you accept the In-App purchase. You not that young and you can read so take action if you must. It's your own fault and all purchases are final. Good luck.

After Clean Install some Mac applications don't work.

I just had to do a clean install of Leopard 10.5.8 with Tiger 10.4. I now have some problems with the Mac software:
1) I couldn't do a Backup Restore for my Mail local folders. I finally moved them from my Previous System Folder. They show up in the Mail Viewer Window, but the contents are empty.
2) I couldn't do a Backup Restore for my Address Book Folder. I finally moved it from my Previous System Folder and replaced the Address Book Folder in Applications. However, it won't open up.
3) System Prefs from the drop-down Finder menu under the Apple symbol won't open up. I can open it from Applications.
4) Safari won't open up from the Dock's @ icon.
If anyone could give me advice to correct these I would be appreciative. Thank you.

Hi,
In some cases "newer" version of an App will not run on Older OS software.
For instance Leopard's iChat 4 will not run in Tiger.
You say a clean install and do not say if you moved your Home Folder Contents back.
Your Mail would have been in there as would the Address Book info.
However related to the first item, you may have issues getting the older Tiger apps to read documents/Databases created by the newer Apps in Leopard.

I had all my software, including my ‘Adobe Creative Suite 4 Design Premium’ removed from my MacPro (OSX 10.10.2) by a Computer technician after I had inadvertently installed some malware.
Now I can’t reinstall my CS4 because the installer software wants me to identify the product from which I am upgrading, but mine isn’t on the list. The old product from which I am upgrading is called ‘Adobe Design Collection’. Furthermore, it has 4 serial numbers (one each for Photoshop, InDesign, Acrobat and Illustrator), not just one, as the installer requires.
I know this can be done, as I have had it working for a long time. Am I doing something wrong now?

Contact support be web chat and have them generate a working temporary serial/ challenge code for the install.

I believe I might have a virus on my mac. Mackeeper shows up 4 times on my download listings but there is no icon on my applications tab. Does this mean I have installed some sort of problem on my computer now?

Hello Last night while watching a video on Facebook a pop up window said I had a virus and to clean it click on the link. I did so and followed a prompt or 2 and then I thought this was a scam so I stopped. However I looked at my download file and it shows Mackeeper listed 4 times. Does this mean I have installed MacKeeper and if so does this mean I have installed some sort of malware/spyware or problems for my computer hence for myself.
Thank you for your help
Maureen

Hi ..
Whatever you do, do not install Norton > Viruses, Trojans, Malware - and other aspects of Internet Security: Apple Support Communities

Installation Failed The installer can't install some files in "/".

The full message is
Installation Failed! The installer can't install some files in "/". Contact the software manufacturer for assistance.
I first received this message when trying to upgrade Pro Tools from 8.0 to 8.0.1 a prerelease for snow leopard. I tried numerous things such as repairing permissions, as well as some pro tools specific things and to no avail. Still got the same error message.
So then I tried completely uninstalling and deleting all things pro tools from my computer. After a clean uninstall and removing all traces of pro tools I proceeded to try and re-install pro tools from my pro tools 8 disk. About a minute into the process I get the EXACT same error message.
I know this issue has been going on since even before snow leopard. I really need to get pro tools installed and running again or at least be able to get the program installed. I've isolated pro tools out of the mix because its been several different installers and even an installer from a dvd. I know this is a Snow Leopard or plain OS based problem. I have repaired permissions, created a brand new user, wiped clean and started over. I don't know anything else to do. PLEASE HELP???!!!

Hi Dean@mac & welcome to the forums...
Any specifics why it wants to install to / instead of Applications, as an example?
Seen these threads yet?

One thing to help investigate the issue is to create a new user just for testing that is stock with no add-on's etc., then login there and try to install. If it works there you can bet there is something unique to your original account that is borking that install - otherwise the issue is most likely global to your system and you might be out of luck until/unless a reportedly qualified version becomes available, etc.
Good luck in any case.

Is it necessary to install some antivirus on my MAC?
