I have just started using Avast Fee 2014.0.9.2011. Immediately I was not able to access legitimate web sites like the UK’s Met Office and BT.com from where I get my email. I carried out a Repair to the Installation and was able to access web sites again, but noticed an Avast Online Security add-on to Internet Explorer was being asked for. Thinking this must be good, installed it and once again I was not able to access legitimate website’s. What is the damned point, I really despair at AV’s. I once vowed years ago never to use Norton after it’s dreadfully intrusive operation. I have since been using Microsoft Security Essentials successfully for several years without complaint, until I read a computer magazine report saying it was not a particularly good Anti Virus program because it is ineffective at blocking malware. This Anti Virus magazine test report hailed Avast Free as the one to chose for protection. Who knows? maybe it is, or has the writer been written a nice cheque to say good things about Avast. So far it’s causing me a headache. AV’s should work quietly in the background should not be intrusive and should block at least 99% of nasty’s. Unhappy Avast user.
