Yes, I read many of these web stories here at FR and it is quite irritating to see how a bunch of finger waggers really enjoy needling folks about porn, yada yada.
Any topic that is extremely likely to be a popular search, is a candidate for these problems. And again, web searches regarding virus removal, is just about the most dangerous of them all.
I get problems blocked while visiting my Photobucket account...doing searches for landscapes, etc.
It is indeed a mistake to think you can only pick up viruses by searching naughty sites.
I run Advanced system care, a freebie occasionally, too.
