This just started a few days ago.
I’m pretty careful about the sites I visit and what I download.
Anyways: Windows 10. Bitdefender Anti-Virus uBlock origin popup blocker. I ran a virus scan and a MalwareBytes scan and nothing found. It finally got so frustrating that I assumed I must have picked up some type of malware so this morning I did a format and clean install. Once back up and running, the only thing I have re-installed so far is AntiVirus, Chrome and the pop up blocker extension for Chrome.
Still doing it. Is this some sneaky new type of ad that the pop up blockers arent catching yet? Mostly seem to be advertising games or “you’ve won an iPhone”.
