How to remove Amnesia virus and restore encrypted files

This page is dedicated to virus called Amnesia which gets onto PC around the world, and encrypts their data. In this article you can see complete info on Amnesia's essence, and how to eliminate Amnesia from the computer. Besides, we will teach you how to restore the encrypted files, if possible.

Amnesia is the undesired program penetrating PC's mostly through Trojans and phishing e-mails. Sometimes fraudsters use exploits to infect the computer, but big program developers quickly correct them. When infection is done, the virus examines the hard drive, defines the quantity of files to be cyphered and their approximate value. Currently, each modern virus is able to cypher video, image, audio and text information in all known formats. Special attention is attracted to businesslike documents, because businessmen are the priority target for criminals. Virus encrypts only information, and doesn't touch the software, so that the user can use his machine to pay the ransom. Encryption is performed via world-known RSA and AES algorithms, and its intricacy is so above the average level that decryption of information without a key is impossible. This is the basis for such a stunning success of this type of viruses in recent years: usual PC operator, even having a fairly good experience in suchlike things, will never be able to restore the files, and will be forced to pay the price. The sole way to decrypt files is to find the scam site and retrieve the encryption keys. Also there's a way to withdraw encryption keys through defects in viruse's program code. The corrupted files acquire.

The computer knowledge is quite substantial in our world, since it helps user to protect the system from computer viruses. For encrypting software this is very important, since, in contradistinction to common suspicious programs, after deleting ransomware from the computer, the consequences of its doings will stay. It's very easy to reduce the chances to get encrypting virus by following these advices:

    • Don't ignore the signs that your hardware or software shows. Information encrypting is a sophisticated process that uses a lot of hardware resources. If you detect a significant decline in system performance or detect a strange string in the Process Manager, you can shut down the computer, boot it in safe mode, and scan for viruses. This, in case of infection, will protect some of your information.
    • Do not accept any alterations to your PC, originating from strange programs. If the system is polluted by Amnesia, it will attempt to eliminate all copies of the data, to make the decryption impossible. However deleting of shadow copies requires admin rights and acceptance from the operator. So, if you do not accept alterations from a weird software at the right moment, you will save the opportunity to recover all lost files free of charge.
    • Closely inspect your mailbox, particularly the messages that have files attached to them. The #1 model of fraud e-mails is the story about prize gaining or parcel receiving. The #2 common kind of these letters is a "business messages". summaries, lawsuits, Bills for goods or services, appeals and other sensitive information cannot come without warning, and you, as a minimum, should know the sender. In most of the cases it is a scam.

Virus elimination is not solution of the whole problem - it's only a first step in the long road before the total data restoration. If you uninstall ransomware, you won't return the data instantly, it will demand multiple actions described in the following paragraph. To deelete Amnesia, user has to boot the workstation at safe mode and run the scanning via antivirus software. High class ransomware can't be uninstalled even through antivirus-program, and have other serious mechanics of security. Many viruses can easily remove cyphered information, or some of it, when trying to uninstall the program. To avoid this, follow the instructions below.
