Seria um vírus (Ati2evxx.exe)? !

Olá,

É o seguinte, acabei de formatar meu PC e instalei o Win XP Professional (ORIGINAL). Acontece que toda vez que eu estou conectado na Internet, depois de uns 5 minutos conectados apareceo erro:

Generic Host Process for Win32 Services has encountered a problem and needs to close. We are sorry for the inconvenience.

Please tell Microsoft about this problem.

Dai minha conexao cai. Eu tento matar um processo que chama ati2evxx.exe e ele da aquela mensagem:

This system is shutting down. Please save all work in progress and log off. Any unsaved changes will be lost. This shutdown was initiated by NT AUTHORITY\SYSTEM

Windows must restart because the Remote Procedure Call (RPC) service terminated unexpectedly

Já ta o Service Pack 2. Acontece que eu nao consigo passar o Windows Update, pois minha conexao cai logo depois desse erro!

Não sei mais o que fazer. Já entrei em vários sites e já fiz quase de tudo, nada resolve!

Segue o log:
