A few days ago I messed up by clicking on show that I am not a Robot. This turned out to embed into my browser and since then I got pop up notifications saying that McAfee discovered 5 viruses on my Linux computer. I don’t have McAfee on this computer.

After browsing for an answer I found these sites:

https://www.pcrisk.com/removal-guides/22484-mcafee-your-pc-is-infected-with-5-viruses-pop-up-scam

https://howtoremove.guide/mcafee-virus-popup-scam/

The 1st link shows what the scam is and has some information on how to block it, the 2nd link shows how to block this scam on several different browsers. I am using Firefox and followed their instructions and successfully blocked the scam’s pop up messages.

I was able to identify the website that needed to be blocked by doing a search for 3.espress-new.com and the search results all said that the site was a scam.

Hope that you don’t need to use this information, but if you do, it should help you solve the problem.
