About this threat
The reason you are seeing You Have Won A Google Gift ads is because of an ad-supported software infection. The main intention of these false advertisements is to trick users into dialing alleged tech-support numbers where scammers would attempt to get remote access to a OS or sell useless programs or services. If you’re dealing with adware , the alerts will be very intrusive. An adware is normally installed by accident, during freeware installation. In case you’re worried, the adverts are quite harmless by themselves, and if you don’t call the con artists, no damage will be done. If you did call them, you would have to deal with professional scammers who would ask for permission to remotely connect to your system, do some weird fix, and then charge money, essentially for nothing. You should never call the numbers in these suspicious alerts, and you should also never permit remote access to your PC to some shady tech-support. And when it comes to this ad, just ignore it, you’re OS isn’t in danger, neither is your data. If you want to stop the irritating adverts, all you need to do is remove You Have Won A Google Gift.
