What is Error #31(0x1F)?

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

Error #31(0x1F) pop-upError #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.

How to prevent from getting adware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
