Error #31(0x1F). How to remove? (Uninstall guide)

removal by Olivia Morelli - - | Type: Adware

Error #31(0x1F) is a scam that encourages people to call a fake Windows Support number

Error #31(0x1F) pop-up
Error #31(0x1F) virus is a scam that tricks people into thinking their device is at risk.
Error #31(0x1F) is a malicious program that displays a deceptive pop-up window with the message about possible system failure or danger to your sensitive information. However, this is a fake alert, and there is no danger to your system or credentials besides the adware-type virus displaying intrusive content without your approval. Typically, the virus is causing a pop-up window filled with a Windows security alert and informing the victim about the presence of malicious programs. Additionally, it encourages people to contact the alleged support via +1-888-905-1666 or other numbers immediately. Unfortunately, calling the number may lead to cybercriminals or scammers who are seeking to get your personal information or money for their “technical support.” Beware that by entering your banking details, you can reveal them to scammers as they can use a fake screen posing a legitimate bank page. You should ignore such alerts and keep in mind that Windows technical support has never asked for money.

Name Error #31(0x1F)
Type Adware/Scam
Category Potentially unwanted program
Symptoms Delivers a fake alert message and commercial content, encourages to call suspicious number
Distribution Software bundles, deceptive websites or advertisements
Main danger Tricks people into revealing their information, collects keystrokes with the screen overlay
Elimination Use Reimage for a general system cleaning and remove Error #31(0x1F)

Error #31(0x1F) pop-up redirects to a deceptive website which displays a message identified as Unknown System Failure but in reality there is no malicious activity that affects the general system of your device. The adware which infiltrated your system delivers all this content. This potentially unwanted program[1] also causes:

  • intrusive commercial content;
  • advertisements in the form of banners, pop-up windows;
  • redirects to deceptive websites;
  • in-text links to malicious sites;
  • installation of additional browser content.

Error #31(0x1F) can also cause slowness of the browser or device in general and this way users get tricked that the system is infected. Nevertheless, your details might be at risk, especially if the message keeps popping up or you contact the suggested number.[2] 

Unfortunately, Error #31(0x1F) virus message is not a program you can find nor delete because the main symptom is the delivery of the message that reads:

WINDOWS SECURITY ALERT:

Your Windows Customer ID: WINDOWS10A182404

Researchers[3] note that similar errors like Error #31(0x1F) can indicate various problems with the device, but there is no need to call the provided numbers. Often these tech support scammers[4] talk with a foreign accent and this fact should be a first indicator that the support is not legitimate.

You should employ a reputable anti-malware program and scan the system instead. This way you can remove Error #31(0x1F) from the system and keep on using the machine safely. You should use Reimage or any other tool and follow the suggested steps. The program indicates possible intruders and terminates malicious programs.

Automatic Error #31(0x1F) removal is the best option because the program causing these fake system alerts comes without your consent or knowledge and often via software bundles or from deceptive ads. A full system scan eliminates all similar programs and browser extensions or plugins. 

Unwanted applications come from visiting suspicious websites

In most cases, potentially unwanted applications like adware, browser hijackers or fake system tools come via software bundles because developers pack their products alongside various freeware and spread these bundles around the internet. When you get freeware from questionable sources, you risk getting additional programs like fake system alerts causing adware.

You can avoid these infiltrations if you choose Advanced or Custom options during freeware installation. By doing so, you get an opportunity to decide what programs get installed on the device. If you skip through these steps and select Default or Quick options, you automatically agree to all additional programs. Also, keep your security software up-to-date, so suspicious websites can be blocked before you enter them.

Remove Error #31(0x1F) and forget about those deceptive alerts and commercial content constantly delivered to your screen. You can do so by scanning the system entirely using reputable antivirus tools. If you have a program that you can trust make sure to follow the suggested steps.
