People have been saying for years that the lack of marketshare equates to virtually no threats to the mac community. While I believe it is partially true, I still think OS X is more secure than Windows. I have never once infected OS X. I'm a literate computer user as I assume you guys are too, and I didn't get the flash back trojan or any other malware. I know there are currently no viruses for OS X, just a little malware like the flash back trojan. But what are the chances of someone coming up with a virus for OS X? Is it even possible? And how do you feel about Apple's response to these security threats with Gatekeeper? I installed that free Norton iAntivirus from MAS and just recently Avast. However I feel that it might be overkill having these programs on my computer and a waste of performance/RAM. Have any of you felt the need to seek out additional security?
