Hello,
It started started at the beginning of august 2008, when AVG 7.5 network ed captured a trojan SpamBot.G with a filename called tcpsr.sys.
It was moved to the virus vault. But the problem was not solved. The file (tcpsr.sys) reappeared. Almost everyday. You delete it, but it comes back.
I have scanned with AVG 7.5, SDFix, CCleaner, ATF cleaner, Spybot. Noone sees a problem.
The scenario is that when You go the the Internet, the file is created to the directory (C:\windows\system32\drivers). And then AVG spots it as a trojan and moves it to the virus vault.

Here is the hijackthis.log of the faulty computer:
