My Norton Anti Virus pops up an information about a Trojan Horse st.exe / strojan.exe, and says it is unable to repair. I've run Xoftspy 3.44, Trojan Remover, Trojan Hunter, System Mechanic SpyHunter, Spybot-SD, Ad-aware 6.0, Stinger, kremove, FxNetsky, FxMydoom, bremove, CWShredder and none was able to find it. When I check the file on C:\WINDOWS\ST.EXE, there it is, but when I try to remove, it wound let me. I try to close the running program by ctrl+alt+del, but it does not appear there, I try then the viwers Pview2 and Asviewer and they also do not show st.exe or strojan.exe, so I am unable to remove it. I also did two other things, turn off the system restore, enter the safe mode, deleted the file st.exe, but it keeps coming back. I've done some 4 online scans, but so far no luck. Is there any other way to solve this? I am using WIN XP Home. Tks for any help, Ricardo

This is all I could find about it. http://www.pestpatrol.com/pestinfo/s/small_trojan_0_1.asp

Try the online scan since Pest Patrol states it can detect and remove it: PestScan – free online spyware scanner from PestPatrol JPQ

Glad you got rid of it Ricardo, posting the link for others. http://www.wilderssecurity.com/showthread.php?t=44389
