I am stupid. Really, really stupid. For no good reason, (since I don't need it and it is not exactly exciting), I decided to download a torrent of a particular well known productivity suite. Now I have read messages elsewhere from people who have downloaded very similar stuff before. Did I mention that my IQ is similar to the percentage of nitrogen in the earths atmosphere? (My only defense is that these other idiots were talking about a preview file which was less than 2MB whereas I downloaded 280 MB) So this .zip file duly downloaded and automatically (?!) unpacked itself. (Zip file ... was that a clue?) I try to launch iCal and am surprised that it cannot be found, so I investigate my Applications folder and the trash but it has gone. Then I notice a large amount of processor and disk activity and it slowly dawns on me that I have been had. The zip file contained a script to do nasty stuff to my machine. Have finally caught on to what is happening I shutdown my machine. Now (having restarted) I can't even tell what damage has been done. Until yesterday I was one of those peole who bragged about how secure and safe and virus free Mac OS X was. Also, I was one of those people who advised against using AV software on Mac OS X. Now I don't feel so good. I am pretty security conscious: i) I use the firewall ii) My OS is up to date with all patches iii) I use Little snitch to catch rogue apps trying to access the internet. iv) I use FileVault V) I use secure passwords (try out apg Automatic Password Generator) but none of this did me any good. Also, I was going to backup my machine last night but the pron was too diverting. Questions: 1) Is there any way I can figure out what has been deleted? 2) Arent recent security patches supposed to prevent this? 3) Would one of the major AV packages have prevented this? DOH! Bad Dobbie! Naughty Dobbie!!!
