Cube virus Removal Guide
What is Cube ransomware?
Cube ransomware – a ransom-demanding malware which uses symmetric or asymmetric cipher for data locking
Cube ransomware - a file locking cyber threat which adds the .cube extension to each file
Cube ransomware is a file-locking threat that uses unique ciphers to encrypt stored data. This malware has been first discovered by a well-known cybersecurity researcher named Michael Gillespie. The purpose of this malicious program is to launch an encryption code on targeted files and leave them with the .cube appendix. Afterward, READ_ME.txt ransom message is displayed and urges a ransom in Bitcoins to be transferred in exchange for the data decryption tool. For evidence that the key truly exists, cybercriminals offer to send them one file for free unlocking. Additionally, two email addresses email@example.com or firstname.lastname@example.org are added as a way to show contact and discuss all matters.

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.
