Issue: How to Fix Error Code: 154-247-087 Pop-Ups?

I’ve recently installed Windows 10 from scratch. Besides, I’ve installed all available updates and several programs that have been lost while installing Windows. A couple of days after that, I’ve noticed doubtful pop-ups on my web browser. These pop-ups report an “Error Code: 154-247-087” and state that the system has some security breaches. I’m using Windows Defender AV. Should I be worrying?

Solved Answer

PC security experts started spreading a warning related to the Error Code: 154-247-087 pop-ups in the beginning of 2017. Many people have been deceived and fall for believing that their PCs have some critical security vulnerabilities, which can be fixed by calling for customer support. We say ‘deceived’ because 154-247-087 pop-ups have been invented by hackers and used as a tool for profit making, as well as malware spreading. According to malware specialists, these pop-ups belong to the Tech-Support-Scam category of malware and should NEVER be trusted.

Usually, people’s web browsers are redirected to a separate page, which contains Error Code 154-247-087 alert. The URLs of the page are altered, but, usually, they include the names like “amazon,” “ebay,” “support,” “Microsoft,” etc. and a set of random letters and numbers. The message freezes the screen and contains intimidating information about what kind of user’s personal information is at the risk. For instance, personal emails, bank credentials, other passwords, credit card information, documents, photos, and so on. To prevent identity theft, the user is urged to call “Windows Certified Tech Support,” which is yet another false claim. The telephone number (0-800-098-8052) provided on the pop-up DOES NOT belong to Microsoft engineers. It’s owned by scammers who may try to trick you into installing doubtful software or provide information to gain remote access to your PC.

Usually, Error Code 154-247-087 ads start showing up in a web browser after installation of third-party software. That may be a download manager, VPN manager, office pack, media player, a game or any other program downloaded from a doubtful third-party source. That’s because these pop-ups are triggered by an ad-supported program, so-called adware.
