Problems with virus

Hi,

I am having real big problems with virus. At my work today a process showed up in task manager called wmedia106.exe.. This programs copies user profiles stored on server and put them in my c:documents and settings/username/...


It copied one new user folder with complete file history every minute. Mcaffee search shows nothing. THen i ran a online search, and it found ptsmon.exe

Further investigation and I found psexesvc.exe and sstore2k.exe

All files are in c:documents and setting/myuserid/temp

I also find all the exe files in c:windows folder

and additional files in windows/prefetch folder

wmedia106.exe-1cfc2e4e.pf
ptsmon.exe-0f1e7539.pf
psexesvc.exe-0cfea159.pf

removing these files and rebooting and they all come back :cry

 

NOTE!

Running Mcafee and it will not detect this. Was found by running Norman av and it reported pstmon.exe as virus/malware

It does not find any of the other .exe files mentioned above

 

I got a stinger to remove the 3 of the 4 files..

The stinger where made by av software team.

It removes all files except for the sstore2k.exe

Waiting for a new stinger to remove the sstore2k.exe
