What is Guster?

Guster is a ransomware type of virus that has been recently spotted by malware researchers. It’s not unique and has much the same characteristics as a lot of other ransomware. It also uses the same spread methods, such as spam emails and fake downloads. Once Guster gets into your computer, it will demand that you pay to get your files back. The reason these kinds of infections are so dangerous is because users can rarely get their files back. Even paying does not necessarily mean you will get your files back.


Do not trust cyber criminals to stay true to their word and decrypt your files once you have paid. It probably won’t happen. We recommend that you ignore the demands and remove Guster. The only way to get the files back would be to restore them from backup, if you had it. However, you can only do that after you delete Guster.

What does Guster do?

Ransomware enters your computer primarily through spam emails. This is the most popular method because users do not take the warnings not to carelessly open email attachments seriously. All you have to do is open the attachments and the virus infects your computer. You need to very attentive when opening emails because any of them could be hiding malware. It might seem like a legitimate email, the sender claiming the attachment is an important invoice you need to urgently review but do not let your guard down. If you don’t want to end up losing your files, consider all possibilities. You might also end up with Guster if you trust random pop-ups with software downloads/updates. They could be hiding various kinds of malware, including ransomware. Only download/update software from legitimate/official websites.

Once Guster is on your computer, it will use complex encryption algorithms to encrypt your files. When the process is complete, you will be shown a ransom note. It also contains audio, so do not be alarmed if you suddenly hear someone speak. The note will demand that you pay 0.4 Bitcoins ($380 or €360) and the developers will supposedly send you the password required to decrypt your files. You are given 48 hours, 6-8 of which would be used by the developer to send you the decryption password. The developer also threatens to “blow up your files” if you try to get rid of this infection, which is highly unlikely. Cyber criminals often use these kinds of tactics to scare users into paying. You should not consider giving into the demands because it will probably not lead to file decryption. It rarely does. Developers usually just take your money and ignore you. You should delete Guster.
