Updated Avast Free Antivirus to 1489 on two machines, IE is very slow afterward because the Avast add-ons are taking 15-60 seconds. When first opened, IE is completely frozen during that time, blank screen and no menu bar. Then when attempting to move to a new web page, the new page takes the same 15-60 seconds to load. Both machines are Win7 64-bit; one update using GUI, the using aswclear in safe mode then a clean install. One machine IE 10, the other IE 9, same issue for both. Disabled the add-ons (Avast Online Security on the IE 10 machine, Avast WebRep on the IE 9 machine), now IE works normally. Only other security software is ZoneAlarm firewall. Any ideas?
Over the last 18 months, at least half my Avast program version updates have brought drama, usually impacting IE. Usually a clean install fixes it, not this time. Very frustrating.
