This post is all about the hazardous crypto-virus called Saverswasted, Removal Guide, File Recovery options, Computer Protection, and Tutorial Video to get rid of the threat.

Saverswasted is a computer threat that is under the category of ransomware. The actual payload of this crypto-virus is to lock majority of computer user’s files and deny their access to important data. Saverswasted uses a complex encryption method to scramble the target files and at the same time, it appends it with .saverswasted file extension.

How Saverswasted Ransomware Spreads?

The entire community of ransomware virus is using typical method to reach their target. Hence, the most efficient of all its tactics is via mass-mailing campaign where Saverswasted ransomware attachment file is sent to thousands of contact addresses. The email is in disguise as correspondence coming from a reputable company and commonly uses subject as Inquiry, Business Proposal, Payment Request, Price Quotation, and similar topics.

As a support deployment scheme, makers of Saverswasted ransomware are also relying on cracked software, malicious ad campaign, drive-by-download, and exploiting software vulnerabilities.

Attack Stages

Once email recipients open the attached file, Saverswasted ransomware launches the attack and starts to implant several malicious files on different local folders. Then, this virus starts to hunt target files and locks them with sophisticated algorithm thus, making it inaccessible. In addition, Saverswasted ransomware appends the encrypted data with a .saverswasted file extension and therefore the common file view.jpg will become view.jpg.saverswasted after the encryption process. To inform users about the current attack, it will leave a ransom note saverswasted_info.txt. The document also contains instructions on how to decrypt the entire .Saverswasted files in which it suggests contacting attackers at the given email address.

Recover Files from Saverswasted Ransomware Infection

On this section, we will provide ways to decrypt files infected with Saverswasted ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting Saverswasted infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by Saverswasted ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of Saverswasted virus.

Emsisoft Tools

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool

Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to ransomware infection. To use this tool as "recovery option" for files encypted by Saverswasted virus, please follow these steps:
