Recently, i got this winupdate32.exe running behind my background. It is making my computer pretty slow and delay the login so I ended it using task manager.
It has another process called update32.exe. these two files are trojans and they trap your keys and send the logins and pass to a hacker website. I change all my pass becos of this trojan. :(
Strange, I got this worm. I didnt download any exe lately. I just join one of those flashchat thing on the web. concidently, this trojan is spread thro irc.
So beware for those who use web chats....u never know who is send u some file in the background.
Anyway, the fix for this is to install a regrun s/w found at http://www.greatis.com/security/
It is shareware but it help to remove the trojan. Great tool...scans whatever that is modifying your system. Alternatively, u can use sophos trojan removal.
