Windows 7: Internet Explorer8 Not responding after opening first page of website

Hi All

I just scanned my computer with anti virus and activated microsoft forefront client security. Since then internet explorer not functioning. I have IE8 installed. When default setting is blank pager, IE opens. Then if click on any website it opens front page and hangs up. Eg: yahoomail opens signing in page and when i enter user name and password it hangs up. Surprisingly google page not responding and hangs up directly. I have scanned my laptop with symantec antivirus and Malawrebytes anti malaware. No luck. Please help.

Go to Control Panel and open Internet Options then click the programs tab and click manage Addons, then disable all of them and see if IE will start ?

Hi ICKYMAY, I did as advised, disabled all add ons, No luck. Still at same posistion. Any more advise.

Initially I would suspect microsoft forefront client security ?

Unninstall or disable it and see if you can get IE working and try another browser ?

You are absolutely right, microsoft forefront client security is the culprit. I have uninstalled TPM and MFCS and I am back on air. Thank you very much.
