Remove Parasite Virus (.parasite Files Ransomware)

Parasite Virus Ransomware

The Parasite mean a ransomware-type infection. Parasite was elaborated particularly to encrypt all major file types. Once the file is encrypted people are unable to use them. Parasite adds the “.parasite” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Parasite, will be renamed into “myphoto.jpg.parasite“. As quickly as the encryption is finished, Parasite places a special text file into every folder containing the encrypted data.

The message given by Parasite text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives. It actually discusses that the info is encrypted and that the only way to restore it is to use a a special decryption key. Sadly, this is definitely true. The sort of cryptography mechanism used by Parasite is still not correctly examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is completely unique. It is impossible to restore the files without the key available.

Another technique of Parasite is that the victims cannot gain access to the key. The key is stored on a particular server run by the frauds associated with Parasite ransomware. To get the key and recover the important information people have to pay the ransom.

Nevertheless, irrespective of the requested amount, people need to keep away from paying the ransom. Cyber frauds are unfair, so they tend to completely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people simply waste their money for nothing.

We highly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Parasite ransomware and to recover the data data for free. Therefore, the just right decision is to recover the lost information from the available backup.

Bear in mind that the world wide web is now overwhelmed with threats that look similar to Parasite ransomware. Malicious programs of such kind are normally elaborated to encrypt essential data and to set forth the need before the user to pay the ransom. The peculiarity of all such ransomware threats is that all apply a comparable algorithm to produce the special decryption key for files decryption.

Hence, as long as the ransomware is still being developed or has some hidden bugs, manually recovering the information is merely not feasible. The only method to prevent the loss of your important data is to regularly create backups of your important information.

Remember that even if you create such backups, they must be placed into a special storage utility not connect to your main computer. You may use the USB Flash Drive or external hard disk drive for this purpose, or refer to the help of the cloud storage. If you store your backup files on your common system they may be encrypted in addition to other files, so it’s definitely not a good storage place.

  • websites rendering free hosting services;
  • pirated peer-to-peer (P2P) downloads.

This is the typical technique used by online frauds to persuade people into downloading and installing Parasite infection manually, by ways of their direct participation in the installation process.

Additionally, the criminals may refer to different e-mail spam techniques to inject malicious codes into PC. So, they may refer to to sending unsolicited spam e-mails with tricky notifications promoting users to download the attachments or click on certain download links, for example, the ones encouraging users to open some video, files, tax reports or invoices.

Needless to mention, opening such files or clicking on such dangerous links may severely damage the system. Fictitious Adobe Flash Player upgrade alerts may result in Parasite ransom injection. When it comes to the cracked applications, these illegally downloaded programs may also contain destructive codes causing Parasite secret installation.
