trojan infected system file

[Gary040]

I get a popup alert from AVG antivirus resident shield that it detects a trojan in the svchost.exe system file
it also reports it as a Vundo virus

xsdbfg.fileave.com/winstallco.exe

I havent been able to remove the trojan even though several scans seem to have cleaned it but the alert still reappears later while using the pc

is there any way to clean this virus without formatting the drive and reinstalling windows?
