hI it is always a good idea to update to the lastest program update especially with antivirus software because of bugs being fixed but I must say to you if you can access all your websites with out any problem with this version of avast free and you have had the lasted version on your computer and you could not access your websites through firefox or Internet Explorer would not connect tor you with the lasted version of avast. I would by all means stay with this version of avast free of avast witch is 9.0.2006 stay with this version for now and go on with having fun wait a while I now it is a pain with the consented popups but hang in their.

I would also file a support ticket to avast tech support on the avast website and tell them of your problem and see if they are close to a fix for this issue.

If you need help leave a message hear.

Hope this helps

have a great day
