Hello, and thanks in advance for your help. I am working on a Toshiba satellite laptop with windows vista on it. The gentleman who has me working on it put 3 different antivirus's on it. AVG, Norton360 and one other I cant remember the name of. I uninstalled these 3 and went to install Avast. Problem is, even tho the lan or wireless say's I am connected, when I click on the IE9 (only browser I have on here) I get a message saying "the webpage cannot be displayed." I notice that all the Microsoft updates can download, but I cannot connect to the web. I even shut off the Microsoft firewall, but still could not connect. Hopefully you can help me. I did not install avast, and the computer, thru the updates, installed Microsoft Security Essentials itself, and that won't even update. Hopefully you can help.
