The pages on the computer keep going funny bringing up the menu pages and drop down boxes. THey are just taking over the screen. I thought I might have had a virus. Something odd happened yesterday a picture of a mouse ran across the web page on mail. Is there anything going about? Also when I click on internet explorer "Globe finder " keeps coming on as home page. I sort this every day and it still comes back.My mouse was playing up yesterday so I swapped it over for my old one. Could this have done anything? Any help welcome.
