So, a few days ago I started getting some major pop-up issues with google chrome. Almost every time I click a hyperlink or even randomly on the page by accident, a pop-up will come up in a new tab. The computer is running Windows 8.1. It's a fairly new machine, only a few months old, and I don't use it for anything promiscuous on the web. I also use AVG for security. I have already tried a few things, including doing AVG scans and general cleaning with CCleaner, but to no avail. I am hesitant to download other programs, because I don't want to get even more viruses from them. Also, I've checked and double checked my installed applications and the google chrome extensions and settings tab, and I can't find anything that's not supposed to be there. This problem is not unique to chrome however, as I am also experiencing pop-ups on Firefox, and also the steam web browser. Just in case though, I did try clearing all my chrome cookies, resetting the whole browser, and even uninstalling and re-installing, also with no luck. So, this leads me to believe that the pop-ups are indeed PC wide, but I don't know where to find the files so I can remove them. If anyone can help with this, it would be much appreciated. Thanks!
