The 1104011-1 engine/virus definitions of Avast contains a problem; it marks a lot of web-sites as and programs as false positives ago.
Right now, their web-sites and download servers are flooded with people frantically trying to update.
Be patient, but do update when you can. The past has shown the flood doesn’t really take that long.
From their Facebook page:
A few minutes ago: 110411-2 UPDATE IS OUT! PLEASE UPDATE YOUR DATABASE.
About 20 minutes ago: PROBLEM WILL BE FIXED WITH NEW DATABASE UPDATE SOON, PLEASE BE PATIENT. THANK YOU.
Oh BTW: If you use the FREE version of avast, then you will have a low priority and receive 403-errors while updating for some while:
Last encountered error: Other HTTP error (403)
