Download and install Ad Block Plus from here. You might also wish to install Ghostery while you're at it. It's also free.

thanks for your help.... i have installed both.

the ads have disappeared, but the black strips that say hide ad are still there? is it perhaps something i downloaded on accident or something? is there anyway to find out at all?

bc also i forgot to mention i am getting green underlining on certain words as ads? this happened at the same time as the other ads popped up
