When closing a tab in internet explorer 8.0 it takes forever. Even when I have only 3 tabs open. I use to be able to have 8+ tabs open in two different sessions with no issues. Nothing new has been added or deleted from the computer. Also open a new tab take very long, not as long as closing a tab. I have deleted cookies, files ect in internet options/del browsing history. I also ran Avast, SUPERAntiSpyware, Malwarebytes and Ccleaner.
