Like (I would assume) most Mac users, Ive not kept a regular antivirus routine. And Im not the blissfully ignorant sort that thinks Macs cant get virusesI know that they can. But I also know that the greatest part of prevention is your own behaviornot installing unknown software, not opening unknown attachments, etc. I did download ClamXav some time ago and ran it a few times (updating the virus definitions before each scan), never finding anything. I updated and ran it again today, and it found something: Oddly enough, the only reference I could find to this specific infection name was a list of viruses added to the ClamAV databaseliterally on todays date. What are the chances of that? I did search for sniperspy and found that the company sells a variety of key-logging, screen-monitoring, and general purpose snoop-ware for different platforms. Im assuming this is the same sniperspy; I dont really know, though. The file thats listed as infected is an official Adobe plug-in for an old version of Photoshop that I dont use anymore. And revealing the file in the Finder, it still shows created and modified dates/times as the sameJuly 19. 2011 8:56 p.m., apparently when I installed it from the DVDs. (The exact same day and time as all of the other plug-ins in the same folder, by the way.) The only possible red flag is that the Save for Web(PS).plugin file is 11.9 MB and the others are less than 1 MB each. So is this a false positive? I dont have anyone (known to me personally) that would have a compelling reason to spy on me, and they wouldnt have the administrator password access to install anything, anyway. And how could that specific file be infected? Would the infection become activated only if/when that plug-in was used?
