I face these a lot, not only on forums but everywhere , one of my friends told me to turn off extensions which I did , it helped to reduce the number of pop ups but still the problem is not totally solved , I think those are by freeze discount or something like that.
But thats the case only on my laptop , when I'm on PC and mobile I didn't face these issues .
That usually means some malicious software on your computer is putting ads on every site. I believe it's called Adware.
http://www.lavasoft.com/products/ad_aware.php is a popular anti-virus to get rid of this.
As for general anti virus, I can highly recommend, amongst paid options, F-Prot which is crazy fast and protects from future threats too (theoretically) as it works mostly by detecting attempts at interfering with core programs, opposed to the usual method of having dictionary of viruses and scanning for them.
Amongst free options, Malwarebytes Anti Malware is an amazing program that focuses on the truly dangerous stuff (the kind that can slow down or ruin your computer big time).
https://www.malwarebytes.org/Definitely the most solid, free, all around option.
Windows 8/10 do come with lots of built in measures, though. I havent needed an anti-virus since Windows 8.1.
