1. How to recognize false prompts and scams

First things first. Microsoft or any security-oriented third-party service will never contact you through a strange looking in-browser dialog box. That’s not how the security programs communicate with the end-user. If you receive a message coming from the Windows Defender’s UI — that’s when you should consider possible virus or spyware infection.

The same goes for third-party antivirus solutions. If the pop-up appears anywhere but in the antivirus control center — there’s nothing to worry about. And, for the sake of everything, don’t click on those pop-ups as they’ll get you in a lot of trouble faster than you think.

In the best case, clicking on one of those will lead you to an Ad. On the other hand, if you lack a proper protective software (all around a bad idea), install malicious software in the background and infect your system.

You’ll recognize them with ease. They mostly pop-up suddenly while browsing the internet. Besides the scary message, they come with a sense of urgency — fix it now or look at the consequences. Suspicious websites are full of these ad-like prompts.
