someone recommended this website to me.
my computer has windows xp. There is some kind of virus/worm which is doing the following things to my computer:
*cant scroll down/up using the up.down arrow
*the boxes in certain websites where we have to type user name/ID are not being displayed of most of the website.
*the boxes on which ok/cancel/save is written are also blank.

please if someone can help me in diagnosing and treating this problem.
