svcsys.exe [Win32: Trojan-gen]

Hi,

I followed the suggestions as far as possible regarding Viruses.

  1. The Virus was Detected when I tried to do a Backup of a Bussiness Folder to another PC. The Avast trial version on the other PC picked this up to be a Virus. I then did a full System scan and my Avast Pro Found the same! I moved it to Chest

  2. I dont know what the source of this virus was and where I picked it up

  3. I am not sure when the virus was downloaded or received

  4. The exact filename is svcsys.exe and Avast Pro says [Win32: Trojan-gen

  5. The wording Avast Pro came up with was 1 Infected file.

  6. I cant use Jotti to Scan the file as its moved to Chest.

My Questions :
What do I do next ?

This page suggests that I try to edit the Registry keys but I am not familiar with fiddling in there and I dont want to brake anything :
