CVCHOST.EXE VIRUS

I have been receiving a message from my Norton Antivirus program as follows:
"System Infected: TidServ Activity 2.  Attacking Computer: Io4undreyk.com (93.114.40.221,  443). The attack was resulted from \DEVICE\HARDDISKVOLUME1\WINDOWS\SYSTEM32\SVCHOST.E

XE. Source Address: 93.114.40.221"

Is there any way I can get rid of that virus? This virus is redirecting my searches to various commercial sites. Norton sometimes can NOT block its operations, sometimes can.

Thank you for your help.
