I installed avast, and my internet explorer will not connect to the internet. When I disable the web shield in avast, as suggested on this website, the problem resolves. I added avast and ashwebsv to my firewall exceptions, which did not work. I updated my just installed avast, which did not work. I updated from internet explorer 6 to 7 to no avail. I installed all available windows updates - no help. I connect to the internet via a home network, and it is working fine. Even while internet explorer won't connect (I get the web page not found error), my AOL connects to the internet no problem. I didn't understand the previous poster's suggestion to manually update the firewall. This seems to be a common problem, and I'd love to solve it if anyone has any suggestions. I am good with computers, but not a techno expert, so please make the instructions simple if you have any. Thanks!!
