win32.agent.zb and Cru629.dat

Hi all.

I have usually managed to fix my own problems, but I think I am stuck. I was hit by something that seems to have been Cru629, as I read a similar description of what happened. My computer started to shut down by itself just after my anti-virus detected something in the temporary internet files.

I turned off my computer by the back switch (and yes I know this is not the prefered method ) and rebooted in safe mode.

I ran CCleaner, ran a scan of my C drive, registry and boot sector with both AVG and System Suite anti virus scanners. They came up clean. I did a system restore and exited safe mode.

I ran a hijackthis log and saw nothing unusual to my untrained eyes, and then ran combofix, which removed cru629. dat, but seems to have found a lingering win32.agant.zb problem with several files. the ones I checked were all modified on the same date in December.

Everything on my system seems to be working normally at this time, all scanners and tools are functioning as far as I can tell.

So, am I still infected?

Please help, thanks so much in advance.

The hijackthis log I am posting was generated after the use of combofix.

I see people posting these in zip format, so I follow that example.
