Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided by practicing safe computing (see below). Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.Is it needed?
ive had Macs since 2010 and haven't had a virus (as far as i no) but with the latest scare, is it worth it? If so which one?
Many Thanks

That's all you need to do to keep your Mac completely free of any Mac OS X malware that has ever been released into the wild. Y
- Make sure your built-in Mac firewall is enabled in System Preferences > Security > Firewall
- Uncheck "Open "safe" files after downloading" in Safari > Preferences > General
- Disable Java in your browser. (For Safari users, uncheck "Enable Java" in Safari > Preferences > Security.) This will protect you from malware that exploits Java in your browser, including the recent Flashback trojan. Leave this unchecked until you visit a trusted site that requires Java, then re-enable only for the duration of your visit to that site. (This is not to be confused with JavaScript, which you should leave enabled.)
- Change your DNS servers to OpenDNS servers by reading this.
- Be careful to only install software from trusted, reputable sites. Never install pirated software. If you're not sure about an app, ask in this forum before installing.
- Never let someone else have access to install anything on your Mac.
- Don't open files that you receive from unknown or untrusted sources.
- For added security, make sure all network, email, financial and other important passwords are long and complex, including upper and lower case letters, numbers and special characters.
- Always keep your Mac and application software updated. Use Software Update for your Mac software. For other software, it's safer to get updates from the developer's site or from the menu item "Check for updates", rather than installing from any notification window that pops up while you're surfing the web.
you don't need any 3rd party software to keep your Mac secure.
No, you don't need 3rd party antivirus software to keep your Mac malware-free, and having antivirus software installed will not provide as much protection as will practicing safe computing. This was clearly illustrated with the MacDefender issue.The above advice is banking on the user being the issue and thats not always the case. Some people may not want AV but you need it regardless
That's because there are no Mac OS X viruses in the wild, and there never has been any.I run an environment with over 4000 users and we haven't had any malware of virii outbreaks.

If you believe that, you're uninformed.I really believe this is bad advice to be giving persons on a message board.
Now this is bad advice. Sophos should be avoided, as it could actually increase your Mac's vulnerability, as described here and here.I use the free version of Sophos
And no antivirus app is 100% effective.NO SOFTWARE is 100% secure.
If they follow the safe computing steps I've posted, they will have zero malware on their Mac, as those steps prevent all Mac OS X malware that has ever been released in the wild.There will be persons that read your advice and are infected with some sort of malware.
I don't need to know their background or computing habits. If anyone follows those tips, they will avoid all existing Mac OS X malware.You have given great security tips, but overall bad advice without knowing a persons background and computing habits.
By running Sophos, you're unwittingly leaving a door unlocked. Depending on antivirus software in the absence of safe computing practices is less effective than practicing safe computing without running antivirus software. This was proven with the MacDefender malware, as no antivirus app identified it as malware when it was first discovered. Yet those practicing those tips were completely unaffected. The same is true for the recent Flashback trojan. Not all antivirus apps detected it, but those practicing those tips were completely protected.I lock my doors at night and also when I leave the house because I do not know who or what may try to enter. I do not think this is paranoid behavior, just common sense. I try to do the same to ensure my OS is as secure as possible without negatively impacting the performance of my system.
I would, too, which is why I practice safe computing, which provides more complete protection than that offered by any antivirus app.Best of luck, but I would rather be safe than sorry.

I really encourage you to read what I've posted and the links provided. Educating yourself about Mac malware is your best defense, rather than depending on some antivirus company, whose motivation is to sell you software.

sorry for a newbie question but if I am running Win7 virtually do I need to treat it the same as Win7 on a PC; do I need to worry more or less about malware than if I was not running Win7 on my Mac?
You need to treat it as running Windows on a separate computer or via Boot Camp, thus AV software is advised. You could use Microsoft Security Essentials for that.
But, at the very least, install some kind of AV protection and practice safe computing.
That's because there ARE no Mac OS X viruses in the wild. Read my earlier posts.I wasn't hit by the virus
You don't need it.They said that they were working on a Mac version and would let me know when it was up and running.
Is it needed?

Porn experts don't need antivirus software any more than other Mac users.you don't need one at the moment if you are not a porn expert
Can you, or anyone else here for that matter, explain to me the threats I am protecting myself against when I install AV software on a Mac? What dangerous threats exist in the wild for Mac OS X that don't require user intervention to install. Or perhaps you can point to a specifc security vulnerability on an OS level that could lead to such things.
Go on, I'll wait. I've been waiting for the better part of a decade for a good reason to install AV software on any POSIX-compliant/compatible system. What's a little while longer?
At the core, anti-virus software is to protect a system from threats that can't be screened simply by having good computing practices. In a system like Windows that grew up and out of a single-user/single-system paradigm, we're talking about an architecture that is insecure from the outset. There was a time when an unpatched XP box could be pwned in less than 30 seconds of being online.
When you're talking about multi-user/multi-system paradigm systems, like UNIX and all of its offspring, you've got a much smaller attack surface to exploit because a lot of those bugs have been worked out for nearly 30 years.
Antivirus for Macs (and Linux, BSD, Solaris, &c.) is lipstick on a pig. It can't protect from the number one threat to those kinds of systems: the user.
