If you have a computer with Windows NT or Windows 2000, you will definately want to run Inoculate IT Or it equal over your entire system. We just spent 17 hours trying to anhialate the poza worm that is causing havock on these systems. It will give you a svchost error, and it infects the system32 files. It places a file by the name of MSBLAST.exe in Winnt/systems32 and a pointer to it registry. If you need further info, post on here and I will reply to your post. PLEASE DO NOT EMAIL ME.
