I noticed there was a problem similar to mine at techspot.com/vb/topic3885. html Mine though has hit all my HD's except C:. When I try to double click the drive it comes up with an error msg. My drive icons are all folders. I can type in the drive letter in the address bar and access the drives (luckily) and when I open my task manager I have a winlogon.exe file loaded that is in my C:\Documents and Settings\user\Application Data. I have tried to get rid of the winlogon.exe and autorun.inf files manually also editing my msconfig startup and services and also the run entries in registry. I have used norton av, avast, avg, mcafee, and a few other virus and mal\spyware programs. Any help would be greatly appreciated, as I don't want to format again. It seems everytime I go onto youtube.com I get some kind of virus. I stopped using it but a friend of mine used my computer and went on youtube and screwed my computer up. Is there a way to stop certain programs from running on a computer without using third party software. I am using WinXP sp3.
