WebPatchwork.exe

A game site I am a moderator and training administrator on had a server attack and I can’t find anywhere, including the link in a previous topic that doesn’t work, if avast protects against this trojan. This is part of the message the head admin left for players " which had caused all main pages to be replaced with a link to down load this trojan, please take care to check for WebPatchwork.exe" Please how do i find out if I am protected against this?

Avast will detect this file.
It will be detected as Win32:Rootkit-gen as of version 4.8.1335.0.
