I have Kapersky 2012 installed on my AMD Athlon 64X2 Dual core processor with 896 RAM, and just recently I am bothered with certain highlighted words that display stupid advertising gimmicks, I dont recall which websites I may have gotten them from but after 3 seperate scans my security doesnt detect a darn thing. I then, installed AdBlock which seems to have corrected the problem tho I think it is only a temporary solution, any thoughts On what else I can do? I run M FF with google browser.
