WinBan is a fake ransomware[1] virus that delivers “Your Windows has been Banned” and “Windows Succesfully Upgraded” screens. Malware prevents victims from accessing their computers until they enter a particular password. Research reveal that entering 4N2nfY5nn2991 code unlocks the PC.

The blue “Your Windows has been Banned” screen imitates Microsoft alert that informs about banned computer because of detected unsolvable threats. Crooks delivers two solutions how to solve the problem – reinstall or verify Windows.

However, authors of WinBan ransomware wants to discourage them from choosing the first option. They claim that installing a new version of Windows will lead to deletion of the files and banned computer.

To rescue data and get back access to the computer, people have to contact “Microsoft Tech People” via phone (+4 075 252 12 657) or email ( and purchase the unlock code.

Nevertheless, finding this lock screen once you run the computer is shocking; you should pay attention to few details that clearly shows that you have been scammed.

First of all, Microsoft does not have a support line. Secondly, look at the contact email address. It’s suspicious and does not sound real. Therefore, enter the unlock code and once you get access to the computer, run a full system scan with FortectIntego. It helps to remove WinBan from the PC.

The picture of WinBan ransomware virusWinBan might deliver two fake messages from Microsoft.

The red “Windows Succesfully Upgraded” window shows that cyber criminals have serious problems with spelling. However, this lock screen window informs about Windows upgrade and asks people to follow particular steps to activate the product.

Of course, grammar mistakes are the clearest sign that it’s a fake message. What is more, at the end it said that this upgrade was created by “Anonymous-Windows upgrade tool.” Keep in mind that all official upgrades for Windows are developed and provided by Microsoft Corporation. And they always proof-read their notifications.

Therefore, instead of following instructions written in the red window, you should reboot your PC to the Safe Mode with networking and starts automatic WinBan removal with reputable malware removal software.

Nevertheless, this cyber threat belongs to the group of ransomware viruses; it cannot encrypt files. As you can see, it has features or scareware[2] and tech support scam. However, it does not make it less dangerous to keep on the system.

Malware distribution strategies

Usually, such cyber threats are distributed via malicious spam emails, malware-laden ads, infected downloads, fake updates, etc.

WinBan malware might get inside your computer if you open a malicious email attachment or click on an infected link. Thus, if you received a strange letter from an unknown sender, you should never open attached documents or visit suspicious sites.

Malware may also be distributed via misleading or eye-catchy ads that might be placed on both potentially dangerous and safe websites. Criminals often use advanced malvertising techniques to put malware-laden ads on popular websites.

File-sharing sites, P2P networks, and torrents might also spread WinBan. Therefore, using these online sources or downloading illegal programs and files, might end up with a virus attack.

Keep away from pop-ups and ads that inform about detected viruses or outdated software. They are fake and usually installs malicious programs on the system.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
