Im getting random Ad's appear on facebook, it is only on there and youtube that im actually noticing them. I have ran AVG, SAS, Ad-aware, AVG reg cleaner, Nod32 and malwarebytes but they are still here.
Im running greasemonkey and Adblocker extentions for firefox, to try remove these ads but they dont seem to be working. If anybody could suggest away i could get rid of them or has came across this before id be grateful for any help. Thankyou in advance
