At any given time I have several chrome tabs open which I switch between. Recently when I look at the tabs at top I often see a tab I don't recognize and when I go to it, its some advert or scam things like the "The brit method" whatever that is. Clicking back does nothing but if I click and hold on back I can see its because the tab has been redirected about 20 times, but it has come from a tab I originally opened. I have checked the program list and there is nothing I did not install, I had used malware bytes and my antivirus several times and nothing. I really don't know what to do about this but it has started happening to tabs I am actually viewing, suddenly it will just redirect to another advert. Does anyone else have any experience with this sort of problem?
