IE 8 cannot access any internet web pages

Hello, I'm having a problem gaining access to the internet with IE, cannot up date avg 8 for virus protection. I can still go on line through Google Chrome and I'm receiving my e-mail but whenever I try to go on line through IE, I get a message saying cannot access this web page, my anti virus is well out of date. Is there some other way to update the AVG without going through IE ? I have tried down loading the update to my downloads but I don't know how to get it installed into the AVG, it says that it is a bin file, whatever that is . I have AVG 8 installed and I have IE 8 installed, my windows program is xp media addition sp3. I don't know much about computer ,only enough to get me in trouble. Has anyone had this problem ??? Help
