    Scareware campaigns are leveraging malicious ads (malvertising) on legitimate websites to display alarming pop-ups claiming dozens of viruses were detected. The fake security software either installs actual malware, creates a recurring subscription charge, or provides a phone number connecting to tech support scammers who request remote access.
