What is "Error #31(0x1F)"?
"Error #31(0x1F)" is a fake (error/virus) alert message displayed only on deceptive, untrustworthy websites. According to this fraudulent alert, an unknown system failure has occurred. It also states that the computer is infected with malicious program/s. These claims are common to websites of this type, however, another problem is that most people arrive at these websites inadvertently, since they are redirected by potentially unwanted applications (PUAs) installed on their systems. These apps are installed on browsers or within operating systems, often unintentionally. They go on to feed users with advertisements and record various data relating to browsing activities.
The entire "Error #31(0x1F)" scam consists of two parts: a deceptive website and a pop-up window displayed from it. According to the pop-up window (supposedly a Windows security alert), the presence of malicious programs was detected and caused error "#31(0x1F), which is identified as an "Unknown System Failure". Users are encouraged to call the +1-888-905-1666 number immediately. According to the scam, this is a Windows Support number. It is stated that failing to calling this number (and solving the problem) might result in having banking information, email accounts, Facebook logins, credit card details, and photos stolen. Apparently, this situation might have occurred due to a suspicious connection to the user's IP address. The website itself contains more or less identical information. This website and associated pop-up window attempt to give the impression that the computer was infected and the user's personal details are at risk. Using this website, scammers attempt to trick people into calling the number (which is mentioned several times in the information provided). When contacted, scammers try to extort money from innocent people by encouraging them to purchase tools that are "necessary" to fix the problem, or they try to trick them into paying for "technical support/guidance". We strongly recommend that you ignore these websites/scams by closing them. If the website prevents you from closing it, use Windows Task Manager and terminate the entire browser process. Do not restore the closed session, since this will return you to the dubious website displaying the "Error #31(0x1F)" scam.
When installed, PUAs force redirects to these dubious websites. In addition, they deploy intrusive ads and gather browsing-related information. PUAs deliver coupons, banners, surveys, pop-ups, and other ads that are usually displayed via tools that enable placement of third party graphical content on any site. They conceal underlying content and, if clicked, often lead to dubious (potentially, malicious) websites or even run scripts that download/install other unwanted, potentially malicious apps. Most PUAs gather browsing-related data, including, for example, URLs of visited websites, IP addresses, geo-locations, search queries etc. They also gather personal/sensitive data. Developers share the recorded details with third parties (cyber criminals) who misuse private information to generate revenue. Thus, having data tracking applications installed can lead to online privacy problems, issues with browsing safety or even identity theft.

"Error #31(0x1F)" is just one of many scams/scam websites that extort money from innocent users. Generally, this is achieved by making users believe that immediate action must be taken to prevent computer damage, sensitive data stolen, and so on. Examples of other similar scams include "Error Code XLMR01F7985", "Windows Is Not Activated", and "Activate Your Windows Now". These unwanted apps are very similar. Most are promoted as providing useful features, however, this is done only to trick people into downloading and installing them. When installed, they perform actions that help developers to generate revenue.
How did potentially unwanted applications install on my computer?
Some people download potentially unwanted apps from their official websites, however, in most cases, PUAs are downloaded/installed through intrusive advertisements or during installation of other software. Software developers often use a deceptive marketing method called "bundling". They use this to trick people into installing unwanted apps together with their chosen software. Developers achieve this by hiding unwanted apps in "Custom", "Advanced" and other similar settings of the installation set-ups. They do not disclose information regarding the presence of unwanted apps in download or installation set-ups. Furthermore, many people install PUAs when they skip installation steps without checking the available options/settings.
How to avoid installation of potentially unwanted applications?
Download software using trustworthy and official sources only, especially if the software is free or ad-supportive. Do not use third party software downloaders, peer-to-peer networks, unofficial websites, or similar sources to download software. Handle all installations with care - check all "Advanced", "Custom" and other similar options/settings and opt-out of offers to install unwanted applications. Many intrusive advertisements redirect users to gambling, adult dating, pornography, and other untrustworthy websites. Do not click ads displayed on these websites. If you are redirected to untrustworthy websites, it is possible that you have inadvertently installed a unwanted, rogue application. Check installed extensions, plug-ins, and add-ons on your browser, and programs on your computer. Uninstall any suspicious/unwanted entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
