Could be loads of things. What protection have you got? Run a few scans via safe then run a HiJackThis scan and upload the results. Never clink links for a start, c/p them into your browser. Try to avoid IE and even FF. FF is the new IE.. Always scan ANYTHING you download before opening it, even summin as simple as an image and try to avoid sw you've never heard of :) I'd also be aware of some IM apps. Mercury is currently the safest (in my opinion) and acts the same as MSN, but with a few very usefull features, such as 'who's deleted me?' 'Who's blocked me?' etc :) Oops, um.. Yeah, loggers.. Run a few safe scans, run a log and upload it :)
