This CouponDropDown pop-ups each time I am browsing merchant sites like ebay and amazon. The CouponDropDown menu will just appear at the top right corner of the screen and shows random ads and coupon discount. I never asked for this and it is very annoying.
Anybody here can please tell me how this CouponDropDown pop-up ad enters my computer. It just started to show one day and I have no single idea how it gets into my computer. Upon searching the web, I found out that the visiting web site has nothing to do with it. CouponDropDown is a virus that affects Internet browsers. My question remains. How did it manage to insert the code into my computer when it is guarded by an anti-virus program?
How can I uninstall CouponDropDown from my Windows when it is not present on the add/remove programs? I need tools and remover to get rid of this virus for the last time. Please advice.
