I was working on a Win 2000 pro machine today and kept getting pop-up "System
Warning" windows saying the registry was corrupted, system is about to crash,
etc. Each one said immediately go to a microsoft website and download
registry repair tools. I became very suspicious because one of the website
references was to a .info domain - somewhere I don't think a legit MS site
would be. I checked the sys event log and the pop-ups said application
warnings - but did not specify the app generating them - I think I may have a
Trojan generating the pop-ups?? Or are they legit?? Thanks
