Protectpcscan.com Fakes Legitimate Branding and Products
Protectpcscan dot com is a misleading website that appears to have been set up for one of two purposes - either to scam people or to make illegal profits.
When you land on Protectpcscan dot com - something that very likely happened after you clicked a rogue ad that directed you to the misleading page - you will see a cleanly designed page that is set up to look like a page from the legitimate website of McAfee. The scam page uses logos, branding and layouts without permission, in an abusive manner, so that it can trick visitors they have landed on an official page affiliated with the security company.
This is definitely not the case. The page at Protectpcscan dot com is a scam and has nothing to do with McAfee, being non-affiliated and not related to the official company site or products. The page has two buttons called "Pick my plan" and "Get protection now". As of the time of writing, neither of those buttons works and they are just static images. It's difficult to tell whether they used to work and linked to malicious or misleading pages or will do so in the future.
When you land on similar pages, make sure to double-check the URL in the address bar to make sure the branding you see on the page matches the URL, to stay safe from similar misleading and potentially malicious pages.
