Hi!!! Another problem! I was innocently chatting using Windows Live Messenger, when I recieved an invitation to accept a file called 'photos.zip', from one of my contacts. I stupidly extracted it and double-clicked on some sort of anonymous file, I think it was called 'webcam_photos_2007_screensaver' or something along those line...
Anyway, at random times, the worm opens up all my online contacts and attempts to send them the 'photos.zip' file, along with a message saying something like 'these are my holiday pictures', and lot of other things.
I have deleted everything to do with photos.zip, and run my AVG virus scanner, where it picks up trojans ( but I believe that is something to do with WinFixer and the WinAntiVirusPro2007 business, which I am currently sorting out). I have run Spybot, McAfee Stinger, but nothing.
