How to remove ShurL0ckr virus and restore encrypted files

If you've suffered from a ransomware and you know that it is the ShurL0ckr program – in our item you'll find useful info. We offer plain and effective tips on ShurL0ckr removal and potential manners to restore the wasted data.

 

 

This virus was discovered by Cylance and Bitglass. Ransomware is a scarecrow of mankind, and every user knows that if a pop-up says: “files are encrypted” – the things are turning bad. It is a true, unfortunately. An encrypting virus is the most dangerous thing that can happen to you on the Internet because a common man literally cannot remove it. The only event when you're able to beat ransomware is when you are not facing a real virus, but an imitation, that covers your display and attempts to lure your funds. In any other case, if a virus was created and tuned in a right way – you can just trust that specialists can beat it. If swindlers committed a mistake, and there are some vulnerabilities, that allow you to recover files – you'll find a cure in this guide.

 

So, what we'd discover if we look inside a ShurL0ckr? It is driven by a totally legal encryption system which changes the folders on user’s workstation, so customer can't utilize them in any approach. That key is also encoded with another method. In most cases, fraudsters choose RSA and AES methods, which have proven themselves the very hard-to decrypt and fail-safe. The mentioned algorithms and the programs based on them are in public access on the Internet, so web-criminals only have to create techniques of protection, to restrict an access to a ransomware, and make the perfect control and update system. Some viruses might work independently, and fraudsters know of a new victim only when he approaches them and transmits the ransom. Other ransomwares are very active, and transmit reports to hundreds servers, to puzzle the malware-fighters and throw them off virus’ track.

 

Regardless of ransomware’s kind, the RSA and AES methods are overly tricky difficult to hack them directly. It might take centuries to execute all necessary operations on a standard home PC or, maybe, few decades in case of usage of a super-powerful computer. We know only two solid manners to beat an encrypting malware: to find vulnerabilities in its code, or break into its database, to get a master key. In some cases there is a breaker, able to cease virus' operation in full or to leave unscathed the infected machine. If someone discovers such breaker for this virus, or create a decryptor, we'll give you full information in this article.

 

Here you can see a few methods to inspect, before you can give in and look for a decryption software. As we said earlier, fraudsters make failures, and some characteristics of the system might support you to recover files.

 

  • If your Windows record doesn't have administrator rights – today’s your fortunate day. The matter is that the Windows replicates any files before their removal or change. These backups are called SVC, and ShurL0ckr has the methods to erase them. If you are employing the usual entry – the OS requests for a authorization at the very second ShurL0ckr starts to erase SVC. If you've seen such request and ignored it – then the copies are alright, and might be used to restore the files.
  • A protected copy is the single fully efficient method to get the data back, but you should uninstall ShurL0ckr prior to it. Ensure that ShurL0ckr is uninstalled completely, as if it isn't – all information will be messed up instantly, including those that were saved on an outer hard disc.

 

In case you examined all these things and you have no possibility to restore the files – you should delete the virus from your machine and wait until a decryption software will be created.

How to remove ShurL0ckr

Unfortunately, there’s no possibility to entirely elude an automatic mode. This ransomware is very cunning and you will definitely pass some elements and then suffer from it (it might happen if you line up an outer drive with your saved information to a not-really-purged device). It also conceals pretty well, and you literally can't get rid of it completely by hand. Here's your deletion directions that will suit all your needs. It consists of several by-hand stages and an optional AV software phase.

How to restore files

Since you cleared your PC of the virus, or at though aware of how you can to do it, let’s talk over the data restoration. As we said before, if you logged in from an administrator entry and you gave ShurL0ckr a pass into the computer – you have no method to recover the files except for the backups. If you use a usual profile – you have feeble odds for data restoration, but it needs specific recovery software. We advise you to use ShadowExplorer and Recuva tools. You can download these programs easily on their official websites, with thorough instructions.

  • Click Start
  • Click Control Panel
