Hello everyone,

Ok, I work in tech support for a regional Internet company, so I am pretty familiar with a good portion of the problems out there. However, the combination I have now seems to have overwhelmed me.

Firstly, I have the about:blank hijack. Secondly, I have apparently got the trojan listed in the title. Back Door Trojan A0 19. I dont know if its connected or not, but I also get this annoying popup all the time asking me if I want to learn more about spyware.

I have run Ad-aware, Spybot, AVG and SYSclean until my fingers bleed, but they seem unable to solve anything, despite adaware constantly finding 40+ things, Spybot finding 5 and Sysclean finds nothing. AVG constantly blasts me with having found the infected file, perhaps every 5 minutes or so, but deleting/moving does nothing.

I have used HJT before to remove this entry :

O2 - BHO: Class - {B7B83230-6E91-B3C1-619A-54550AB911E0} - C:\WINDOWS\system32\atlqg32.dll

However times I remove it, it always reappears, but always under a different name.

Attached is a HIJACKTHIS log.
