Rastakhiz virus Removal Guide
What is Rastakhiz ransomware virus?
Rastakhiz ransomware – a virus that locks all personal files and demands a ransom
Rastakhiz is a HiddenTear based malware that is designed to encrypt files on the targeted computer. Ransomware appends .RASTAKHIZ file extension in order to make files inaccessible. Following this destructive behavior, the virus delivers a poorly written and impolite ransom note.
The ransom note tells that users are “screwed” because the ransomware encrypts their images, videos, songs, text files, and other data. Victims are asked to transfer the ransom of 250 USD to the provided Bitcoin wallet address until the given time expires.
|Type||Ransomware, cryptovirus, file-locker|
|Symptoms of infection||Personal files are encrypted and renamed; ransom note appears|
|Criminal contact firstname.lastname@example.org, email@example.com|
|Distribution||Fake Flash Player updates, file-sharing platforms, spam emails|
|Elimination||Instead of paying the criminals, remove the ransomware and use alternative data recovery options|
|System health||Use the RestoroIntego PC repair tool to fix all system irregularities that the infection might have caused|
The ransom note provides detailed instructions on how to pay the ransom and claims that developers are the only ones who can help to get back access to the encrypted files, and users should trust them:
“Don’t worry about decryption. We will decrypt your files surely because nobody will trust us if we cheat users.”
Victims are also asked to provide their unique ID number and email address in order to receive the decryption key. According to the researchers, the authors of the ransomware will respond within 6-8 hours via firstname.lastname@example.org or email@example.com email addresses. However, it’s doubtful that Google won’t notice such strange activities and won't suspend these accounts.
However, no matter what criminals promise, you should not believe them. No one can assure if they keep their word or have a working decryption software. Thus, it’s better to remove Rastakhiz from the device to avoid money loss and make sure that your computer is safe to use again.
Additionally, some of the files might be restored with HiddenTear decryptor or other third-party software. However, if you have backups, you should not worry about criminals’ demands. You should opt for the removal immediately.
Keep in mind that crypto-viruses are complicated cyber threats. They might affect legit system processes and install numerous malicious components. Thus, you should use SpyHunter 5Combo Cleaner, Malwarebytes, or another legit malware removal tool to eliminate all malware-related files safely.
Once you eliminate .RASTAKHIZ file virus from your device, you must use the time-proven RestoroIntego software to repair corrupted system files, fix broken DLLs, and remove all traces of the infection. This tool will also delete all tracking cookies that might endanger your privacy.

Avoid file-encrypting viruses by taking precautionary measures
Rastakhiz, as well as many other crypto-viruses, spread via malicious spam emails, bogus downloads, fake updates, or malicious ads. Malware researchers from Bedynet report that any antivirus, anti-malware, anti-spyware, or another sophisticated security program cannot fully protect a device from malware. Thus, users should protect themselves by following these tips:
- Do not open suspicious or spam emails. If you open it, do not click on any content, such as links, buttons, or attachments, because they might install malware on the PC.
- Before opening email attachments or other content, always check the information about the sender and the issue.
- Download software from the publishers of developer’s websites only.
- Stay away from torrents, P2P networks, file-sharing sites, and similar free sources because they often include malicious content that looks like safe programs or cracks.
- Do not download illegal content, including programs, music, movies, etc.
- Update software from the official sources and ignore pop-up alerts that might appear on various websites. They are always malicious.
- Make backups and update them regularly.
