Problem was with bad Avast update (110411-1). Check your Engine & Definition update status and if you have that one, run another update. Avast had their update servers down for a little while to prevent further spread of this issue, but they are starting to come back up with 110411-2 update, which fixed the issue. May have to try to run updates several times until you hit a server that is able to provide that update. Had two client with this issue, both fixed by update.
