How to remove 1btc virus and restore encrypted files

If you have faced a ransomware and have grounds to suppose that it’s the 1btc ransomware – on this site you'll receive help. We propose simple and efficient advice about 1btc uninstalling and possible ways to recover the spoiled files.

What is 1btc ransomware

Encryption virus is a worricow of our society, and we all know that if a pop-up says: “files are encrypted” – the things are going bad. It’s a right reaction, unfortunately. An encrypting virus is the worst thing that might happen to you in the Net as a common man literally can't get rid of it. The only event when you're able to overcome ransomware is when you’re not dealing with a real one, but an imitation, that blocks your display and attempts to trick you into paying a ransom. In any other event, if ransomware was created and adjusted in a right method – you should only trust that malware fighters can defeat it. If swindlers made an error, and a malware has some vulnerabilities, which give you an ability to get back files – we’ll tell to you what to do in the following entry.

 

 

So, what we'd see if we look inside a ransomware? It consists of a completely legal cryptography algorithm which changes all data on user’s computer and makes them worthless if you have no key. The key is also encoded with another algorithm. In most cases, fraudsters prefer RSA and AES algorithms, which are famous for their complexity and fail-safety. The mentioned manners and the programs based on them are freely available on the Internet, so swindlers only have to add mechanisms of protection, to block an access to a program, and create the perfect update and control scheme. Some encrypting tools just act independently, and fraudsters get a report about another "client" only when he approaches them and sets off his money. The complex encrypting viruses are very active, and deliver files to thousands URL's, to puzzle the malware-fighters and maximize the efforts required to beat a ransomware.

Regardless of ransomware’s sort, the RSA and AES algorithms are too tricky difficult to bruteforce them. It it requires thousands of years to make all needed calculations on a modern device or, maybe, twenty or thirty years if you will use an industrial gear. The only method to beat a high-quality encrypting malware is to find vulnerabilities in its code, or hack its server, to find a master key. In some cases there is a switch, allowing to cease virus' activity totally or to leave unscathed a particular PC. If any parson discovers such breaker for .1btc, or create a decryptor, we'll update this article.

 

Here we've gathered a few things to test, prior to yielding and looking for a decryptor. As it is stated above, swindlers also fail, and certain peculiarities of your Windows might serve you to restore data.

 

  • If you don't use the OS through an admin entry – today’s your lucky day. The catch is that your operating system replicates any information prior to their uninstalling or modification. Suchlike backups are called Shadow Volume Copies, and the virus knows how to eliminate them. If you're working from the user's profile – the OS requests for a permission at the exact moment 1btc tries to erase these copies. If you've seen such thing and declined it – it means that the SVC are fine, and could be used to recover the data.
  • A protected copy is the only totally productive manner to get the information back, but you should uninstall 1btc prior to it. Make sure that .1btc is gone fully, because if it isn't – all info will be spoiled instantly, including the files that were kept on an outer hard disc.

 

If both of these hints didn't help and you have no way to recover encrypted files – you should remove the virus from your machine and wait until a decryption program will be published.

How to remove 1btc

As for the uninstalling – you can't fully elude an automatic mode. 1btc is too stealthy and there is a chance pass some remains and then regret it (for example, when you connect a flash data storage with your saved information to a not-completely-purged device). It also conceals very good, so you literally won’t have an opportunity to get rid of it completely by hand. Knowing this, we’ve developed a solid uninstall specification that will suit all your needs. It consists of some manual steps and an optional antivirus software step.
