Selfdefscan[.]site in detail

Selfdefscan[.]site performs a fake system scan that supposedly detects threats on the operating system. Also, selfdefscan[.]site is designed to instill fear and urgency in the visitor by falsely claiming that their Windows system is infected with viruses and other malicious applications.

It asserts that immediate action is required to remove the viruses and repair system damage. The message urges the visitor to proceed with a virus removal procedure immediately. Additionally, a warning is issued, stating that if the visitor leaves the site without taking action, their computer will supposedly remain damaged and vulnerable to further attacks.

This tactic aims to pressure the visitor into following the instructions provided on selfdefscan[.]site. The website prompts visitors to renew their McAfee license, creating a sense of urgency regarding the expiration of their antivirus protection. Upon clicking the "Renew License" button, users are redirected to a legitimate McAfee page.

Closer inspection reveals that the URL contains an affiliate's ID, indicating that the operators behind selfdefscan[.]site are receiving a commission for McAfee products sold through their link. It is important to note that McAfee is a legitimate software company that does not use sites like selfdefscan[.]site to promote its products.

Also, none of the warnings and claims on selfdefscan[.]site are true. Another detail about selfdefscan[.]site is that it wants to send notifications. If allowed, it may bombard users with more fake warnings and similar messages that could lead to potentially malicious pages, various scams, etc.

Thus, selfdefscan[.]site should not be allowed to send notifications to avoid computer infections, monetary loss, identity theft, or other problems.
