System restarts!!!

[prankie]

I have a sempron 2500+ OC'ed to 1.53Ghz, with 512 MB RAM and is running on Windows XP pro (Genuine)..
Recently my system started giving problem.. it restarts every now and then..
i scanned my pc and found "Trojan house Backdoor.Agent.atu" on c:\windows\svchost.exe
i removed it.. but still the prob prevails..
plus aftr removing this virus, when ever i disconnect and reconnect my bb connection, system fails to connect to the internet.. so i had to restart the system to reconnect!!
I am using zonealarm pro firewall and AVG Pro antivirus.

the legit ms svchost is situated in C:\WINDOWS\SYSTEM32\SVCHOST.EXE
