What is Assist Ransomware
Using a set of cryptographic algorithms, Assist Ransomware encrypts personal data and claims money for its decryption. This practice is highly-popular around ransomware infections as they make everything possible to leave no choice to desperate victims. Because of powerful ciphers applied by Assist, manual decryption becomes quite an arduous task. This is why cybercriminals offer to contact them via the
email@example.com e-mail address and receive further instructions. This information is listed inside of the note (ASSIST-README.txt) created after your data is locked completely.

Not to mention that this version of ransomware encrypts files using the .assist extension. To illustrate, a file like
1.mp4 will get a new look of
1.mp4.assist after the encryption is done. As mentioned, the only possible method to get 100% decryption is with the help of ransomware developers, however, this is not the best option since they can fool you and do not give any software for restoring the data. We strongly insist on deleting Assist Ransomware from your computer to prevent further encryption, especially if you do not regret the lost data that much. As an additional measure, you can try some third-party tools to run partial decryption, but this might not revive all of your data. Whatever the case, both removal and decryption tips can be found down below.
How Assist Ransomware infected your computer
Infections like Assist Ransomware are usually spread via spam messages, trojans, fake software cracking tools, backdoors, keyloggers, and other dubious channels. The most prominent, however, has been around spam messages that contain malicious attachments. This is might be the most lucrative method for extortionists to deliver malicious programs. As it covers a wide range of users, more likely the traffic of successful infections will satisfy the expectations of developers. They disguise such messages as legitimate companies promoting their services. Usually, there is a file attached to the message. If you are being asked to open it up, then it is a trap meant to spread malware. In order to prevent this and many other channels from reaching your PC, you should be careful and stay away from untrusted content. Additionally, you can get some anti-malware software involved. We have some of it discussed down below.

Assist Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
