Hi Geeks,

I found my computer doing scans on whole groups of IP-addresses at port 445 again. Ewido and Ad-Aware found and removed threats yesterday (e.g. ssl.exe) but today no infection was found but the scans continue and they are breaking down my router again and again.

Here's my HiJack This log:

I got rid of it myself. I was wondering about the running process "wtcpcom.exe". The file (in C:\WINNT\SYSTEM32) was created last night when the problems occured for the first time. I had also seen some .tmp process before I had went to bed yesterday, this file was almost as new as the wtcpcom.exe. I couldn't kill wtcpcom.exe by Win Task Manager but ewido "analyse" could. It restarted itself after each termination. I rebootet into safe mode and deleted the files among some others created last night as well. I backed them up in a RAR archive, so if anyone is interested in this virus file, which was not found by any of the tools listed on this site (nor in normal nor in safe mode), i could send it to you. Even google did not return any result for this filename, so maybe the virus is very new?

Anyway, I should go to bed now.
