A user reports frequent messages appearing on their desktop stating that their system is infected with a virus and they need to pay to have it cleaned. What is the most likely explanation for these alerts?
Windows 10 Home PC require additional licensing for Windows Defender
Legitimate Windows OS security notification for updating security settings
A legitimate antivirus software update
Normal Windows OS behavior indicating a scheduled scan completion
These desktop alerts are indicative of a scareware attack, where malicious software tricks the user into thinking their system is compromised with the intent of extorting money for a 'fix'. Real antivirus solutions do not ask for payment in exchange for virus removal in this manner. The user should be advised not to follow any payment instructions and to run a legitimate antivirus scan to remove any potential malware.
