Hello,
I've seen similar threads in connection with the "ymovielive" (https://forums.malwarebytes.com/topic/274615-browser-hijacker-returning-after-deletion-and-uninstallation-help/) or "UHelpShow" (https://forums.malwarebytes.com/topic/274606-trojan-browser-hijack-extension-keeps-coming-back/page/2/?tab=comments#comment-1461622) extensions and tried to follow some of the steps, but unfortunately the solutions were all custom made and the generalized parts didn't help me.
After multiple scans and the use of AdwCleaner there are still regular pop-ups of iw.gamegame.info being blocked. I feel really uncomfortable knowing that there is something like that in my system and would really appreciate some help with that problem.
