Win32:Malware-gen in C:\Windows\System32\svchost.exe

Hi, can anyone help me to get rid of this? I ran a deep scan that removed a couple of other files, but this keeps on popping up every few minutes:
We've safely aborted connection on 3.tlu.dl.delivery.mp.microsoft.com because it was infected with Win32:Malware-gen
The process is listed as C:\Windows\System32\svchost.exe

Can AVG Antivirus Free get rid of this at all?
