Chrome periodically opens a new tab with the website "gametopages.org" and if I leave it open for more than 30 seconds, I cant close it. I have to go into task manager and close Chrome from there. I have reinstalled Chrome a few times, I have run virus scans on my computer and have found it's very likely on here, so i'm worried its an extension that I see in the extension manager or something is getting into my google account... any input?
