Over the weekend I updated my virus/adaware/malwarebytes programs and re-installed Firefox in an effort to get rid of a Pesky PopOp screen that appears in the lower right hand side of the screen: it appears when I click on news articles through MSN; it makes an instant message sound "blur-eeep" sound and in the upper right corner it says "chitka" and is very annoying to the point I can't read the script; how can I get rid of this? Additionally, I am almost always Redirected to an site that is associated with the topic I am reading. I've tried many things to rid myself of these redirectings.. . any help!! Thanks in advance!!!
