Usually, when I go on the Internet Explorer. The page I am on just closes. It doesnt come up with a message it just closes down and thats it?! I could b on something really important and it just closes, it is such a pain!
I think your PC may have a virus or Trojan, You could download Kaspersky internet security suite and try that for 30 days for free. I have just ditched Norton in favour of this as it is far better at detecting viruses and trojans. If you are running any anti-virus and firewall protection you will have to remove them from your system before installing kaspersky. Good luck hope it goes ok
