Brother, I believe everytime u restart u will find an exe with a new number

in the temp folder
I had a similar virus/worm if not this one
Install NOD32 and a firewall immediately(i would recommend PCTOOLS fireall plus)..its free
and one more thing
C:\Document~1/Admin/Locals~1/temp/e7952.exe/autorun
here autorun is the argument passed to the exe file
