What is McAfee SECURITY ALERT?
McAfee SECURITY ALERT is a phishing SCAM that pretends to be a security alert from McAfee. The scam uses social engineering techniques, which are nothing new.

QUICK LINKS
When users land on one of the sites running the scam, they are presented with an alert disguised as a McAfee security warning.

It is important to emphasize that there are no websites capable of detecting that a computer has been infected, therefore websites making such claims are always scams.

The collected information can be used to make fraudulent purchases and unauthorized transfers, sold to criminals on the dark web, or other malicious purposes. Moreover, the criminals can use stolen email addresses to send spam and malspam (spam emails containing malware or links to malware).
