BleepingComputer.com: Favicon changes randomly in IE7 tabs

I had updated to IE8 but after it running very very slowly, I uninstalled IE8 and reinstalled IE7 from Microsoft's website.
Then I had problems with a couple of Trojans that I got rid of with the help of the Malware forum and ever since Internet Explorer 7 seems to be behaving strangely.

What happens is that the little icon in the tab of the browser, changes randomly to another site that I may have visited. For example, when I visit the BBC site, my tab should show the little BBC icon. Instead it now shows the icon for RAI News 24 that I visited recently.
Also, the Google icon has changed to another site visited - and the Bebo icon has changed to a cookery icon. The changed icon is also shown when I click on Favourites to go to a particular site.

I have read some stuff on other forums but no one seems to be sure how to deal with this problem.

Also I don't know if this is the correct forum to post this question.

Any help would be appreciated as it is rather annoying.

Thanks

Giovanni

EDIT - since writing the above I seem to have solved the problem - I used ATF cleaner to clean out all temporary files (whilst IE shut down) and everything then went back to normal. Though I don't know how permanent this solution will be. If any further problems arise - I'll be back.
