What is the best online malware check to use

What is recommended as the best online malware check on the IMAC?

VIRUSES
No viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions.
It is possible, however, to pass on a Windows virus to another Windows user, for example through an email attachment. To prevent this all you need is the free anti-virus utility ClamXav, which you can download for Tiger and Leopard from:
http://www.clamxav.com/
The new version for Snow Leopard and Lion is available here:
http://www.clamxav.com/index.php?page=v2beta
Note: ClamAV adds a new user group to your Mac. That makes it a little more difficult to remove than some apps. You’ll find an uninstaller link in ClamXav’s FAQ page online.
If you are already using ClamXav: please ensure that you have installed all recent Apple Security Updates and that your version of ClamXav is the latest available.
Do not install Norton Anti-Virus on a Mac as it can seriously damage your operating system. Norton Anti-Virus is not compatible with Apple OS X.
FAKE ANTI-VIRUS SOFTWARE and associated MALWARE
Do not be tricked by 'scareware' that tempts computer users to download fake anti-virus software that may itself be malware.
Fake anti-virus software that infect PCs with malicious code are a growing threat, according to a study by Google. Its analysis of 240m web pages over 13 months showed that fake anti-virus programs accounted for 15% of all malicious software.
Scammers trick people into downloading programs by convincing them that their PC is infected with a virus.
Once installed, the software may steal data or force people to make a payment to register the fake product.
Beware of PDF files from unknown sources. A security firm announced that by its counting, malicious Reader documents made up 80% of all exploits at the end of 2009.:

TROJANS and RE-DIRECTION TO FAKE WEBSITES
The appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
You can read more about how, for example, the OSX/DNSChanger Trojan works (by falsely suggesting extra codecs are required for Quicktime) here:
http://www.f-secure.com/v-descs/trojan_osx_dnschanger.shtml
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
http://macscan.securemac.com/
First update the MacScan malware definitions before scanning. You can also contact their support team for any additional support - [email protected]
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
http://macscan.securemac.com/buy/
and this can perform a complete scan of your entire hard disk. After 30 days free trial the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)
A white paper was published on the subject of Trojans by SubRosaSoft, available here:
http://www.macforensicslab.com/ProductsAndServices/index.php?main_page=document_ general_info&cPath=11&products_id=174
Also, beware of MacSweeper and MacDefender (also goes under the name of MacProtector, MacGaurd, MacSecurity or MacShield) :
These are malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer in an attempt to obtain payment.
Mackeeper is equally worthless and should also be avoided. Again, the developer seeks to obtain payment for an application that does nothing that free utilities do not also offer, and in many cases it will also mess up your system.
You can keep up to date, particularly about malware present in some downloadable pirated software, at the Securemac site:
http://www.securemac.com/
HOW TO AVOID RE-DIRECTION
Adding Open DNS codes to your Network Preferences, should give good results in terms of added security as well as speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
http://support.apple.com/kb/TS2296
There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac, and alternatives will probably appear in the future. In the meantime the advice is: be careful where you go on the web and what you download!
WHAT TO DO IF YOU THINK YOUR MAC HAS BECOME 'INFECTED'
If you think you may have acquired a Trojan, and you know its name, you can also locate it via the Terminal:
http://theappleblog.com/2009/04/24/mac-botnet-how-to-ensure-you-are-not-part-of- the-problem/
Although any content that you download has the possibility of containing malicious software, practising a bit of care will generally keep you free from the consequences of anything like the DNSChanger trojan.
1. Avoid going to suspect and untrusted Web sites, especially p'orn'ography sites.
2. Check out what you are downloading. Mac OS X asks you for you administrator password to install applications for a reason! Only download media and applications from well-known and trusted Web sites. If you think you may have downloaded suspicious files, read the installer packages and make sure they are legit. If you cannot determine if the program you downloaded is infected, do a quick Internet search and see if any other users reported issues after installing a particular program.
3. Use an antivirus program like ClamXav. If you are in the habit of downloading a lot of media and other files, it may be well worth your while to run those files through this AV application.
4. Use Mac OS X's built-in Firewalls and other security features.
5. Peer-to-peer sharing applications and download torrents (such as the now defunct LimeWire) supplying pirated software, movies etc are hotbeds of potential software issues waiting to happen to your Mac. Everything from changing permissions to downloading trojans and other malicious software can be acquired from using these applications. Similar risks apply to using Facebook, Twitter, MySpace, YouTube and similar sites which are prone to malicious hacking: http://news.bbc.co.uk/1/hi/technology/8420233.stm
6. Resist the temptation to download pirated software. They can contain Botnet Trojans. SecureMac offer a simple and free tool for the removal of the iBotNet Trojan available here:
http://macscan.securemac.com/files/iServicesTrojanRemovalTool.dmg
YOUR PRIVACY ON THE INTERNET and the latest risks to look out for:
There is the potential for having your entire email contact list stolen for use for spamming:
http://www.nytimes.com/2009/06/20/technology/internet/20shortcuts.html?_r=1
And if you are using iPhone Apps you are also at risk of losing all privacy:
http://www.engadget.com/2010/10/03/hacker-claims-third-party-iphone-apps-can-tra nsmit-udid-pose-se/
The advent of HTML5 may also be a future threat to internet privacy:

Security of OS X generally:
http://www.apple.com/macosx/what-is/security.html

Security Configuration for Version 10.5 Leopard:
http://manuals.info.apple.com/en_US/Leopard_Security_Config_2nd_Ed.pdf
NOTE: Apple's Snow Leopard and Lion operating systems silently update the malware protection built into Mac OS X to protect against a backdoor Trojan horse that can allow hackers to gain remote control over your treasured iMac or MacBook: Macs running Snow Leopard or Lion now check for new malware definitions daily, allowing Apple to quickly deploy protection from threats before they have a chance to spread.
Few malicious titles actually exist for Mac OS X, and those that do rely almost entirely upon duping users to install software that pretends to be legitimate.
http://www.sophos.com/blogs/gc/g/2010/06/18/apple-secretly-updates
However, if you are running Lion Server:
Apple's new server operating system -- OS X Lion -- is so inherently insecure that Stamos recommends keeping it off the network altogether and using Macs only as standalone machines connected to IP or Windows networks, not those designed for Macs.
The Mac Server's networking protocols -- especially DHX User Authentication -- are designed for ease of use, not security. It is trivial, Stamos said, for hackers to set up a Mac user to download a file that will overflow the buffer protecting the heap segment of the server's memory, allowing the file's malicious payload to run uncontrolled in the server's memory and give itself whatever access rights it wants.

What is the best online backup system to use for mac?

By online, do you mean backup to the cloud, where you pay a monthly fee for the service to host your data?
If this is the case, then there are a lot of services (do not know them all, but DropBox, CrashPlan, Carbonite, Mozy, SugarSync, come to mine, and that is not a complete list.
There are also services that allow you to backup over your home network or across the internet to your own storage. CrashPlan has this option (for free), and Transporter come to mind. CrashPlan talks to another computer also running CrashPlan that you own or have some control (could even be a friend or relatives computer). Transporter is hardware that you either provide some storage of your choice, or they will sell the unit with storage.
I'm mostly a CrashPlan to my own storage user. I backup to a Mac mini for my Mom (300 miles away) and Wife (she is local )

What is the best antivirus/malware protection software for a MacBook Pro?

I bought my MacBook Pro in April of 2011 and it's been running fine ever since then. I do not keep too many files on my laptop and have everything backed up on a 4TB external hard drive. I have programs that keep my MacBook running smoothly and as fast as possible by clearing out unnecessary files. Recently, my MacBook has become slow and I now normally have to click on a button at least three times before the page loads or refresh the page. Sometimes I even have to force quit Safari and restart from the beginning just to load a web page. Programs will quit unexpectedly and downloading something takes ten times longer. I fear there may be something wrong with my MacBook and it might have a virus or something. What is the best antivirus/malware software to download? I'm leaning towards Norton Antivirus for Mac or Intego Mac Internet Security. Could someone please help me?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. 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 victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
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, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; 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.
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.
For the reasons given above, App Store products, and 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. OS X 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're not absolute protection. The first and best line of 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 malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
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 untrustworthy.
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 in this category, 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.
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.
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 from malware.
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.
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 virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do 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 is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, 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.

If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect anything targeting the Mac because there
     is no Mac malware in the wild, and therefore, no "signatures" to detect.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

I am a new mac user and I switch to mac due to the graphics that it brings. I do website in pc and I heard iweb is the best.NOW i heard that iweb will be discontinue. so what is the best application there for website using MAC OSX lion?

It is now confirmed that iWeb, and iDVD, has been discontinued by Apple. This is evidenced by the fact that new Macs are shipping with iLife 11 installed but without iWeb and iDVD.
On June 30, 2012 MobileMe will be shutdown. However, iWeb will still continue to work but without the following:
Features No Longer Available Once MobileMe is Discontinued:
◼ Password protection
◼ Blog and photo comments
◼ Blog search
◼ Hit counter
◼ MobileMe Gallery
All of these features can be replaced with 3rd party options.
I found that if I published my site to a folder on my hard drive and then uploaded with a 3rd party FTP client subscriptions to slideshows and the RSS feed were broken. If I published directly from iWeb to the FPT server those two features continued to work correctly.
There's another problem and that's with iWeb's popup slideshows. Once the MMe servers are no longer online the popup slideshow buttons will not display their images.
Click to view full size
However, Roddy McKay and I have figured out a way to modify existing sites with those slideshows and iWeb itself so that those images will display as expected once MobileMe servers are gone. How to is described in this tutorial: #26 - How to Modify iWeb So Popup Slideshows Will Work After MobileMe is Discontinued.
It now appears that the iLife suite of applications offered on disc is now a discontinued product and the remaining supported iApps will only be available thru the App Store from now on. However, the iLife 11 boxed version that is still available at the online Apple Store (Store button at the top of the page) and those still on the shelves of retailers will include iWeb and iDVD. Those two apps were listed in small, gray text on the iLife 11 box that I bought.
Personally, if I didn't already have a copy I would purchase one to have it for reinstallation purposes if ever needed.
This might be of some interest to you at this time: Life After MobileMe.

Get rid of Norton a/k/a Symantec. It is one of the worst pieces of trash you can install on a Mac.
You do not need any additional anti-virus software than is already designed into OS X to protect your Mac against malware. I assume you paid enough for your iMac and that's part of what you paid.
If you use Windows, or are concerned about harboring viruses that target Windows, or care about friends who use Windows, then get ClamXav. It's in the App Store and it is free.
Since friends don't let friends use Windows, I have no use for it.
