1. It is much slower recently than when I first bought it - in particular when loading my personal settings and connecting to the internet.
2. I.E. frequently stops responding.
3. I bank online and when I go to log on an about:blank window appears for a second then disappears. This has only recently started.
I have carried out all the suggestions on the Malware and Spyware Cleaning guide and should be very grateful for any help you could give me.
