AVG found nothing. I think I’ve got Windows 10 and Firefox browser. But the problem persists even after the negative AVG deep scan. Voter fraud? What voter fraud? virus, we can name it. Or how about Biden Wins or Jeff Epstein-cide?
I would scrub your Firefox Internet cache and all your saved pages and cookies . You may have to login again to sites and you will lose your history, but that is the first thing I would do.
It’s probably Firefox. I recommend replacing AVG with Avast! and using Avast’s secure browser instead of Firefox. Firefox is buggy and subject to zero-day malware attacks.
