any help would be greatly appreciated ive never had a virus before so am unsure as to what to do.

Try a forum search for this file name as there have been a couple of them about this detection.

This is one of them and it may be a false positive, also see this post http://forum.avast.com/index.php?topic=102118.msg817370#msg817370 and http://forum.avast.com/index.php?topic=102118.msg817393#msg817393.
