This is now the second time I've had a system do this. Here is the symptoms I've seen: -File associations all screwed up. LNK, EXE, and likely more. -All icons missing in start menu, or just some sticky ones (like Run and Help) -You can't open All Programs at all. -In the Start Menu, "My Computer" is renamed "Files" for some reason. -IE missing toolbars. Address bar and Links bar are gone. Not just pushed to the side or unchecked in the view menu, they are GONE. They don't come back or show up no matter what's checked. -You can, however, change the home page in settings, BUT NO page can display. Instead, any page with "http://" tries to download instead of display. So for example if you set the home page to www.google.com and then open IE, a box pops up right away asking to save the file "google" and where to save it to. If I save the file, it saves the HTML file. If you open the file, you see the HTML code. So basically it doesn't display a page, it just wants to download it. Very strange. If I set the home page to an ftp page, it actually tries to open it, but of course can't do it. At least it doesn't try to download it. Meaning somewhere in the registry the MIME types are screwed or whatever. Now here are some other notes. I can't find out what this virus/malware is because it will not do a virus scan. You can't do anything with IE. Safe Mode is trashed as well. You can't use Firefox or Netscape for online virus scans, don't even know if other browsers would work anyway. I took the HDD out of the system and tried to scan it on my own box, it crashed my virus scanner and locked up. Then caused a "Delayed Write Failed" message to keep coming up. Like I said I've seen this now only twice. I can't find any information about it, what virus causes this, how to kill it, etc... Both completely different systems with XP, and exhibited the SAME behavior. So that leads me to believe it is just one virus that does all this stuff as it's payload. It's a bad one, trashes associations, kills IE toolbars, kills Start Menu, kills HTTP protocols, kills virus scanners, trashes IE. All I can really do is reload. Anybody else seen this? I'm trying to find out what it is so I can research it. Any ideas? Thanks.
