Whenever I have 2 tabs open on an IE page and close them down using the red X I get the normal question 'close all tabs'. When I select 'yes' it closes the page I am on and opens a new IE7 window along with multiple tabs. The tabs just keep increasing in number and will not shut down. I can eventually shut it down in Task Manager but this tends to take 5-10 minutes before it will successfully 'end program'.
Even once the page is closed down very often a new one opens up immediately and we start the process again.
I have run scans with A-Squared and Avast anti-virus but nothing comes up.
