Hope someone can assist -

I am now unable to display websites which require a login. I can display my Yahoo homepage, the TV page, the sports page etc, but if i try and click on 'Mail' when it would normally go to the login screen, it loses the connection.

Similarly, on my bank's website, the home page is fine but if I try to log in it stops working.

I recently upgraded to IE8 and wondered if this was the problem, but having downgraded back to IE7, it is still happening.

It happens in both Internet Explorer and Firefox.

Thinking it was an issue with my security settings, I have tried Tools - Internet Options - Advanced - Reset but still not working.

Please advise
