I have the same problem with the file nstask32.exe, in C:\WINDOWS\SYSTEM32 (I have WINDOWS XP/PRO). It was created by the virus "TrojanDropper.win32small.bc. It was what the AVP antivirus informed. I deleted the file. Also had the file win32sockdrv.dll, it was the virus "Backdoor.sdbot.at. I deleted it too. The virus made the connection, when using a chat or a P2P program, to get cut. After deleting the two "virus file", and before, always have the same message when starting :windows can not find the nstask32.exe file. The problem continues, but the computer takes more time to get disconnected. I don't know what configuration must change in order to avoid it. I would really appreciate some help

I got this same worm. i dont know how i got it either. everytime i boot up i get cant find nstask32.exe and i deleted the win32sockdrv.dll file said it was a virus, some randy or something virus. how can i fix my pcand how did i get this i dontknow. i was using irc and talking but i ddint write anything or anything. someone must of hacked me but i dont know how. cause i know i didnt do anuything or download or run any stuff unless it came from some internet site that has a file with a virii in int. i know i didnt run any weird stuff. but i get that error too.

Hi Everyone. The Trojan tried to leave nstask32.exe but it failed so it just left a stupid entry in your registry which makes logon extradordinarily slow. Here's the entry I found: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon String Value Name: Shell Type: REG_SZ Binary Value: explorer.exe nstask32.exe Just remove the part after the explorer.exe and your logon will be back to normal. Cheers

Where do I find my registry on WindowsXP so I can remove the above? Regards Daniel
