Ok I have MCafee

I'm looking at a goggle search page,I find a web site I'd like to click on,it has been checked and okayed by Mcafee,because it has a green check mark after the web page,and I click on it,a window pops up,saying windows security clean pc,and acts like it is running a scan on my pc,and just that fast ,another window pops saying I have viruses on my pc,click ok to clean them off,I try to click to x them off,another window pops up,are you sure ,you want to leave your pc infected,I click on cancel another window pops up and it won't click off either,so I have to delete.control and alter to get to task manager to stop it,because,it won't click off at all,so I run a complete scan and find nothing on my Pc.
I have adblock plus to stop these pop ups.
Does anybody else get these?
