Infected by Downloader Trojan - Please help

Recommended Posts

Hi all,

I've come across a problem where my computer constantly downloads data when connected to the internet. I've tried searching for malicious entries in my HJT log but could not find any. The only clue I have so far got is that SuerpAntiSpyware once detected Trojan Downloader SFUR : Extort in bitb3.tmp file. I cleaned it but the problem is still there (maybe it didnt get cleaned properly).

 

HJT Log is posted below. Please help me find any suspicious entries in this log. I've heard bitb3.tmp is associated with Trojan Downloader Zlob. Does this seem to be the case?

 

Also, I've heard that C:\WINDOWS\system32\cidaemon.exe is widely used by downloader trojans. Is there any truth to it?
