So i recently got a trojan, and using malwarebytes anti malware i got rid of most of the files pretty easily ( i dont remember the name of the trojan)
But now, i have 1 file left that keeps coming up on MBAM and it replaces itself each time it gets deleted within like a minute, and keeps coming back on reboot.

the file is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit (Trojan.Agent) -> Data: c:\windows\system32\userinit.exe

malwarebytes scan

Reinstalling Service Pack 3 should solve this problem (I'm assuming you have Windows XP).

i was getting Antivirus XP Pro pop ups i believe when i woke up also and saw all this

edit: once i deleted all those files i was left with the userinit file again and some C:\windows\system32\win32hlp.cnf file, which i think that maybe these files keep loading up those other files or something? Both these files are considered Trojan.Agents

I think it's time to head on over to the HijackThis forum for a closer look.

Preparation Guide for use before posting a HijackThis Log

Go straight to Step 6. Be sure to include a link to this thread so they can see what has already been tried.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

THIS IS MY OPINION, I AM NOT A HELPER OF THIS FORUM!!
You May have the W32/Virut virus or a variant. From the names of the files, and what is apparently a polymorphic action, that would be my best guess.
