![]() ![]() ![]() When OS X viruses or other dynamic malware reach the point that they are rapidly affecting users despite safe computing habits, I'll install one. ![]() I haven't tried any package recently so I can't judge them now, but I just don't see the need. It generated several GBs of inactive RAM and slowed my system down. Like I said, I'm not opposed to AVs at all and tried Avast back on OS X Mountain Lion. I'm less than thrilled with Apple's speed towards fixing them however. These are clever hackers and scientists, but at least the recent discoveries have been to protect the users and not to attack them. Potentially, a new Sony flash drive you just purchased could have a firmware virus. If the firmware attack is very new and dynamic (which seems to be the case) the AV won't stop it on the software side. Physical access is one of the most crucial points which is why all companies (including Apple) recommend putting your computer to sleep when you're away and using a password along with FileVault. If someone malicious has unfettered, unsupervised physical access to your hardware, you're boned. You just take physical security of your machine more seriously. Being owned by a hacked thunderbolt (or USB) device - there's not a lot you can do other than have fixed EFI firmware in your mac.īut that doesn't mean you just throw your hands up and say "it's possible that some vectors can bypass my scanner! there's no point at all!". You can safely detect Windows malware with no risk of being owned and warn others.Īn AV package can protect against a firmware hack being run in the first place if it is the type that runs on your machine via a web exploit or whatever and then infects your firmware. Malware definitions are much quicker to push out than developing, testing and distributing a security update is.Īnd the other benefit of AV is that you aren't passing windows viruses on to windows using friends or colleagues. AV definitions are often updated multiple times per day (i.e., you will be protected before Apple patch the hole and perhaps before you read about the malware or the site operator fixes their hacked site). However some AV programs do heuristics (i.e., they make an intelligent guess at flagging code that looks dodgy). ![]()
