OK I will try to describe this as best i can. Just recently i noticed the close symbol (x) in the top right of my browser had become coloured and pixelated. It still works if I click on it just cannot see the X symbol. If I try to close a word doc from the toolbar the symbols are also corrupted and when I just now right clicked on the toolbar and a download box I got the same. Anythoughts, I am running XP and have avast and malware bytes.
