Help needed with Trojan-Clicker.Win32.Delf.cbe

Hey guys,this is my first post here so please bear with me.My laptop is infected with what Kaspersky IS 7 tells me is : Trojan-Clicker.Win32.Delf.cbe.It detects a .dll file in system32 folder (sayuhxrd.dll) as being infected by this virus and thow i booted from a live CD and manually deleted that file it's back in the same folder,with the same name after restart.I use win XP fully updated and i'am "protected" by KIS 7 also up to date.Normally i would just format/reinstall windows but i really need to keep my windows setting just that way they are because i use my laptop for work….well…you get the point.Thanks a lot guys,hope to find a solution soon.

Please follow the instructions here and then start a NEW thread and post a brief description of the problem and a new HijackThis log and somebody will be along as soon as.

I'll lock this one.
