How Did I Get Into the McAfee Online Scan Completed Scam?
- You browsed a website that shows rogue advertisements or uses ad networks that serve malicious pop‑ups.
- You might have clicked on a link from an email, social media, or via search engines that took you to a site that auto‑redirects you or triggers malicious pop‑ups.
- Possibly adware or unwanted software is on your system that’s causing repeated pop‑ups.
- Browser notifications may have been allowed accidentally for suspicious sites, enabling persistent alerts.
What the McAfee Online Scan Completed Scam Actually Does
- It displays a fraudulent scan message, often saying something like:“We finished checking X files for threats. 1 malware threat was detected.”
- Then urges you to click “REMOVE THREAT NOW” (first pop‑up)
- Followed by a second pop‑up:“Your device is still at risk… your protection is inactive… activate your subscription now with a discount.”
- Uses the McAfee logo and layout to look legitimate.
- Clicking the call to action may redirect you to the real McAfee site or to affiliate links. In many cases, the end‑point is trying to sell a license or get affiliate revenue. PCRisk found that in their test the redirection was to McAfee’s official site via affiliate channels. PCRisk
- However: that affiliation does not equal legitimacy in the context of scare tactics; there is no valid scan, threat detection, or any genuine security service being offered in that pop‑up.
Should You Be Worried About the McAfee Online Scan Completed Scam?
Yes — because:
- It manipulates fear to try and extract money, personal or financial data.
- It may expose you to additional threats (fake antivirus, unwanted software, malware) especially if you click through.
- Even if it redirects to legitimate products, you’re being manipulated, and your system could already be compromised (adware, trackers, etc.).
- Trusting these pop‑ups can lead to identity theft, financial loss, and long‑term risk to privacy.
But also: the scam itself doesn’t always infect your computer by itself — often just deceit. The danger largely comes from ensuing actions taken by the user.
Removal Steps for the McAfee Online Scan Completed Pop‑Up Scam
