Its a paid adblocker. I wouldn’t recommend it but I don’t think its a virus. Hard to say without being able to check it myself tho.
Thats a screenshot upon login scammer.info. The owner will maybe let us know?
We can’t control Google ads
Just click the X and it’ll go bye-bye. I use AdGuard along with a popup blocker and never get anything…here nor anywhere else.
I don’t get popups on any other site so I wondered if someone is attempting to attack the soldiers of this site. Also when I have saw any popup never on both sides like that. That is very unique. Thanks
I recommend UBlock Origin
Absolutely love that extension
Not a virus just a scam 
You can certainly blacklist/block advertiser domains in Google Ads.
