I signed up for a free copy of Avira which at the time I was happy with. All seemed to be working well until a virus hit and knocked out the functionality of Avira completely. I therefore had to download a different anti-virus package to clear the virus and never went back. From my experience of Avira the scans are thorough but it might not be able to deal with the virus once it finds it.
