Three times this weekend AVG has asked me to update AVG free.  Each time I try the update fails.  It keeps highlighting the computer component as the only update needed.  Last week I used AVG Pro on trial period.  I didn't like the results & didn't buy it.  Is that what AVG is trying to update?  Now I can't run a scan on AVG free.  It just shows "scan interrupted."  I can't find anything running that would interrupt.  Please Help.
