🙂 Excellent news, Trilo!
Thanks very much for your scan info too:
Trojan.Downloader
Trojan.Agent
Trojan.Dropper
Backdoor.Bot
These made up most of the infected objects, the rest was Adware.
Crikey. I've seen BackDoor.Bot in similar contents (associated with "some of the required files are missing" messages when launching iTunes). But the adware isn't to be sneezed at either. (A few years ago, one of the most common causes of an error-message-free QuickTime and/or iTunes launch failure was Qoologic adware.)
If you've got an Adobe Reader version 8 or 9 on your system, be sure to make sure that is up to date, in order to close off the possibility of further infections by that vector. I think it probably might be worthwhile running regular Malwarebytes scans for a while, too just in case
QuickTime is a vector. (That BEX has me a bit worried ... a buffer overrun is a common means by which malware can attack a program.)
