Also Known As: Ads by systemopc.xyz
Damage level: Medium

What kind of page is systemopc[.]xyz?

Systemopc[.]xyz is an untrustworthy page running the "McAfee - Your PC is infected with 5 viruses!" scam. Our team has discovered this site while inspecting other websites that use rogue advertising networks. The purpose of systemopc[.]xyz is to fraudulently promote legitimate software and receive permission to show notifications.

Systemopc[.]xyz page in detail

Systemopc[.]xyz displays a fake system warning claiming that Windows 10 is infected with viruses and other malicious applications. Those viruses must be removed and system damage repaired. That message urges visitors to run the virus removal procedure immediately. It also warns visitors that closing systemopc[.]xyz will leave the computer damaged and vulnerable.

Clicking the "Renew License" button on this page opens the official McAfee website with an affiliate ID in its URL. It means that systemopc[.]xyz is operated by affiliates who aim to collect illegitimate commissions from purchases made through their page. McAfee is legitimate antivirus software that has nothing to do with systemopc[.]xyz.

Another detail about systemopc[.]xyz is that it asks for permission to show notifications. Notifications displayed by systemopc[.]xyz can be used to promote various scams, shady apps, or even malicious software. Thus, it is strongly recommended not to agree to receive notifications from pages like systemopc[.]xyz.
