Posted 03 August 2010 - 11:04 AM

Noticed freezing windows, then Generic Host Process error, and finally IE navigating by itself.

AVG noticed the "Trojan Horse BackDoor.Agent.AHXQ" tried to remove, and now no longer detects it, but the system is still misbehaving.

Generic Host process error sig:
szAppName : svchost.exe szAppVer : 5.1.2600.5512 szModName : unknown
szModVer : 0.0.0.0 offset: 001a3b57

error report contents:
c:\docume~1\ellenm~1\locals~1\temp\WER90f7.dir00\svchost.exe.mdmp
c:\docume~1\ellenm~1\locals~1\temp\WER90f7.dir00\appcompat.txt

ark and attach are attached

DDS follows.
many thanks.

Hmm--well, I think I'll be rebuilding the system this weekend: if it's possible to reply Thursday--and I understand it may not be--that would be useful. Thanks.
