How do I stop various Ad internet explorer pages poping up on my screen?

Yes, you are right, antivirus are not smart enough to catch adwares. Some adware can really be nightmares. Now coming to point...

Are you sure you want only IE and nothing? In that case, update your IE to IE8 (if you havn't done so already). Turn on popup blocker and phishing protection.

I would suggest you to download free antispyware from

www.superantispyware.com/download.html

Install and update and run a full scan.

Hope your problem is solved.

Using mozilla or Google chrome would certainly help you a lot.

you probally have some spyware installed on your computer that prompts these pop-ups every time you log on. Go to control panel in your start up menu and click the icon for add remove programs. Look through the list for programs that you don't need and remove them. If your not sure if you need the program or not then don't eraseit. Find out what it is first.But the program your looking for will probally have the same name as the ad you keep seeing
