How to remove Datarestorehelp@ virus and restore encrypted files

If you've faced a ransomware and you know that it’s the Datarestorehelp@ virus – in our article you will find help. We suggest easy and effective instructions about Datarestorehelp@ deletion and practicable manners to restore the encrypted files.

What is Datarestorehelp@

Ransomware can be considered a roadkill of mankind, and everyone knows that if a pop-up says: “files are encrypted” – it’s time to worry. It’s a true, by the way. Datarestorehelp@ infection is the most dangerous thing that can happen to you in the Web since a regular customer has no resources to delete it. The exclusive case when you can overcome an encrypting virus is if you’re not dealing with a real virus, but a screenlocker, that covers your display and tries to lure your funds. In all other cases, if ransomware was created and adjusted in a proper way – you should only hope that malware researchers can beat it. If fraudsters failed somehow, and a ransomware has some vulnerabilities, that allow you to get back files – you'll find an answer on this page.



Ransomware type does not actually matter, as the RSA and AES methods are too complicated to bruteforce them. It it requires hundreds of years to execute all necessary calculations on a usual device or, maybe, twenty or thirty years if you have an access to an industrial gear. There are two basic manners to beat an encrypting virus: to hack into it, or hack its server, to find a master key. Rare ransomware examples also have a switch that can stop ransomware's operation in full or to make it pass the infected machine. If someone finds that switch for this ransomware, or make a decryption program, we'll update this item.


So, what we'd find if we look inside a ransomware? It consists of an absolutely legal encryption algorithm which modifies all folders on operator’s computer, so customer cannot use them in any manner. That key is also encoded with another algorithm. As usual, web-criminals prefer RSA and AES manners, that have asserted themselves the very hard-to decrypt and fail-safe. These manners and the programs based on them are in free access in the Net, so swindlers just need to invent techniques of defense, to restrict an admittance to a program, and make the flawless update and control system. Some encrypting tools may act independently, and scammers know of a new "client" not before he turns to them and sets off his ransom. The complex viruses are very active, and deliver reports to hundreds addresses, to confuse the researchers and throw them off virus’ track.


There are a few possibilities to inspect, before yielding and looking for a decryption tool. As it is written in previous paragraphs, swindlers also fail, and certain peculiarities of your operating system might support you to recover data.


  • If you do not use the system through an administrator's account – it's time to compliment yourself. The thing is that your operating system creates backups of all information before they’re destroyed or changed. Suchlike backups are called SVC, and the malware knows how to erase them. If you're operating from the user's profile – the OS requests for a confirmation at the very moment Datarestorehelp@ starts to erase those copies. In case you've seen suchlike request and ignored it – then the copies are safe, and could be used to restore the files.
  • If you have a copy of the information, and placed it on the outer media – just eliminate a ransomware and use it. Ensure that the virus is gone totally, since if it isn't – all information will be spoiled instantly, including those that were kept on a flash drive.


In case you examined both these opportunities and you have no way to recover your information – you should delete Datarestorehelp@ from the system and wait until a decryptor will be developed.

How to remove Datarestorehelp@

Unfortunately, there’s no possibility to entirely avoid an automatic mode. This virus is very cunning and you could miss some parts and then suffer from it (for example, when you attach an external data storage with your saved files to a not-totally-cleared machine). It also hides pretty good, so you just can't delete it entirely in manual mode. According to this, we’ve developed an efficient uninstall instruction that will suit all your needs. It contains several by-hand steps and one extra antivirus tool stage.
