Sure: AdBlock, Adobe reader and Video Downloader All. I downloaded them all some time ago on purpose from the proper channel.
I wish to make clear that as soon as a page whatsoever downloads, an overlay is loaded on top of it where any click no matter the place starts the redirects popups and popunders. I checked it via Chrome's own developer tools.
Wait, i did a Chrome reset after your fix and it seems everything is back on course. I will keep you posted for updates but as for now everything seems okay... thank you for your help
