About the fake WIN.DLL0151930 error

A scary warning

When a WIN.DLL0151930 warning shows up, it can be a little overwhelming. It plays jarring audio of alert sounds and attempts to expand to full screen so as to lock your screen.

ALERT! MICROSOFT FOUND VIRUS

Windows Error Code : WIN.DLL0151930

This computer is BLOCKED

The WIN.DLL0151930 warning discourages you from closing the window or turning off your computer. It claims that your Windows registration key is illegal, that your computer is being hacked, and that you must call the provided phone number to reactivate your computer.

Overall, the warning is concerning and it might cause you a lot of stress.

Dangers of the scam

If you were to call the provided phone number, the person on the other side would tell you to install remote access software (Fastsupport, Helpme.net), connect to your computer, take control of it, and install some crapware, all while pretending to be genuine Microsoft support.

In the end, the scammers want to convince you that they’ve rescued your computer from certain doom. They want to charge you hundreds of dollars. If you don’t pay, they might lock your computer, such as by setting a new password and not telling you about it.

What causes the WIN.DLL0151930 warning

Unexpected redirects, pop-up ads, bad browser extensions, and adware viruses may cause the WIN.DLL0151930 page to appear on your screen:

• Some websites regularly show dangerous ads. If the same website always opens the WIN.DLL0151930 warning, then be careful of the other ads that the site shows, too.
• Websites are vulnerable to malware attacks, too. Some get infected with malicious code that forces them to open websites such as the WIN.DLL0151930 alert.
• Malicious browser extensions and desktop programs may cause redirects to WIN.DLL0151930 warnings and other bad websites.

If the WIN.DLL0151930 pop-up appears only when you visit certain websites, then it’s probably caused by an advertisement on the sites that you visit.

If the alert shows up unpredictably and pop-up ads open on their own, then an adware infection may be behind this.

How to avoid tech support scams

Don’t be scared by fake warnings

The WIN.DLL0151930 alert is very eager to scare you and to stress you out. However, the real Microsoft is not like that.

For example, the WIN.DLL0151930 page claims that your “window’s registration key” isn’t right and that’s apparently enough for your computer to be BLOCKED.

However, the real Windows isn’t like that. In recent years especially, pirated versions of Windows work just fine and Microsoft doesn’t come after individual users for stealing their software (Techradar.com). So, even if your Windows version was stolen, you might never hear from Microsoft about it.

Recognize scam pop-ups

Familiarize yourself with scams. For instance, you can find a whole database on Popupdb.org that you can look at. Once you know how the fake pop-ups look, you’ll never fall for tech support scams.

Also, remember that Microsoft does not show any phone numbers on its security alerts. It’s just not done. If you want to contact Microsoft support, you have to do it yourself.

How to deal with the WIN.DLL0151930 scam

Don’t fall for the scam

Close the WIN.DLL0151930 page. Don’t interact with it and don’t follow its instructions. If you’re not sure how to close it because it’s locked your screen, this post has some advice.

If the WIN.DLL0151930 page downloaded a file, go ahead and delete it. Most likely, it’s just the webpage itself in that file – if you open it, it’ll show the WIN.DLL0151930 warning again. But it could also be a malicious program.

Scan your computer with an antivirus program, like Spyhunter, Malwarebytes, and others. If adware viruses or other suspicious items are detected, remove them.

Block malicious pop-ups

Block malicious websites and ads with an anti-malware tool or with an ad blocker. Malicious advertisements are a big source of malware infections so, blocking those sites from appearing on your screen would help your security tremendously. Staying away from infected websites and from sites that willingly show malicious ads (pirating sites and free streaming sites are big offenders here) would also help.

Also, make sure to allow Windows and your antivirus tools to download and install the latest updates. This way, your PC will be more resistant to various malware threats.
