Hi, I have Windows NT 4 server having MS-Exchange 5.5 server in one machine.
Am running corporate emailing system. When I connect it to the Internet for
Internet mailing after sometimes it give me services.exe error and then all
services hang. The system also create U.Exe file in C Drive and replaces my
services.exe file with U.Exe file. I know its a trojan but not found any
remedy yet. Kindly guide me for the removal of this virus and I would
appreciate if someone guide me for NT4 Server TCP/IP and other securities.

Regard,
