Have followed all steps on the guide, and there is no trace of obrona in programs, or in chrome extensions. However, the pop-ups continue. I've tried 6 different adware/malware removal tools, and still no joy.
Accepted AnswerPCrisk SupportTomas MeskauskasOffline0Hi Syd, Obrona BlockAds is an adware which infiltrates user's computers through free software downloads. The most important step when removing this adware is uninstalling all suspicious applications using Control Panel. Notice that Obrona ads can be implemented by various other app developers to monetize their free software. After uninstalling all suspicious applications and making sure there are no "Obrona BlockAds" plugins in your Internet browsers (following this removal guide - https://www.pcrisk.com/removal-guides/8129-ads-by-obrona-blockads) you could scan your computer with Malwarebytes Antimalware (https://www.pcrisk.com/top-spyware-removers) and AdwCleaner (https://toolslib.net/downloads/viewdownload/1-adwcleaner/). After this procedure your computer should be adware free - let me know if this helped. At the time of writing this reply there are two known adware programs developed by Obrona - Obrona BlockAds and Obrona VPN.
