Trojan horse IRC/BackDoor.sdBot.27

On running AVG it found this virus.

Trojan horse IRC/BackDoor.sdBot.27

AVG then moved the file to the virus vault and everything seemed ok for a few days. However, then it started picking up the virus' activity again yet running AVG would not detect it.

The virus appears to be in a directory I can access.
C:\System Volume Information\_restore{10D4B4EE-7COB-4339-9C74-309162FA969}\RP16\A0001667.exe

I have run both AD Aware and SD Spybot (amazing what they find) but still this virus/thing keeps popping up.

Heres the Hijackthis log.

heres hoping you can help.

 

Hi Smallfry,

Before you start, please unzip hijackthis to a separate folder. The program will make backups in the folder in the folder it's in.
These easily get lost in a Temp folder.

Check the items listed below in HijackThis, close all windows except HijackThis and click Fix checked:

O2 - BHO: (no name) - {FDD3B846-8D59-4ffb-8758-209B6AD74ACC} - (no file)

O4 - HKLM\..\Run: [Windows Update] C:\WINDOWS\System32\virfa.exe

Reboot into safe mode and delete:
C:\WINDOWS\System32\virfa.exe

The file AVG found is in your Restore Points.
To clean those out, disable System Restore, reboot, and re-enable System Restore.
Disabling or enabling Windows XP System Restore

Regards,

Pieter

 

yay!

The Firewalls calmed down and AVG seems to have settled down as well.

Thanks for the help

 

My pleasure.
