I’m kinda worried at this point. My PC keeps giving me notifications, saying that my computer has been infected and that I should call some technitial to deal with that. Should I do that? I was wondering if I could just simply use some antivirus software without having to call someone to fix my PC? By the way, it all sounds suspicious to me because I never had these ads before AND I do not have an antivirus system that would send such notifications. Is there something I can do to stop receiving these notificaitions? Or is my system really at risk?
