ILS32,
The advantage of scanning with HouseCall is that it gives you a second opinion. The payload of some viruses is to disable your current antivirus program. (It will look like it is scanning but it is in fact not doing anything.) Since HouseCall is not resident on your computer, it will not fall prey to this type of attack. The second thing is, many people do not update their antivirus program, and my scanning with HouseCall, at least we know the person we are helping has at least one good scan of their system.
Take Care,
Richard
P.S. As long as AVG has the virus quarantined you are safe.
