Welcome to our TeslaCrypt 4.0 Virus removal instructions. This article intends to help you remove TeslaCrypt 4.0 Virus from your system and is designed to work for all Windows versions.

TeslaCrypt 4.0  is an especially vicious computer virus of the Ransomware variety. It is in fact a new and “improved” version of the notorious TeslaCrypt line of ransomware applications. You may have heard of them if not encountered them before. An incredible amount of people have suffered as a result of the TeslaCrypt Ransomware. This new version – TeslaCrypt 4.0, by early reports is supposed to be even worse and harder to remove than TeslaCrypt 3.0 for instance. We are not saying any of this to discourage you but to emphasize on the fact that you are indeed in a serious bind and have to act quickly if you are to salvage anything out of this situation. In this article you will find information on how TeslaCrypt 4.0 Virus operates, how it has found its way into your system and some thoughts on whether you should pay a ransom or not. After that you will find an easy to follow TeslaCrypt 4.0 Virus removal guide as well as a possible way to recover your encrypted files.

TeslaCrypt 4.0 Virus – how does it operate?

Since its first version that came out in March of 2015 the TeslaCrypt Ransomware has evolved a lot. Just as all other Ransomware applications TeslaCrypt 4.0 uses a Trojan horse to infiltrate the victim’s computer device. Just as the previous versions it uses the Angler exploit kit or EK for short. Once inside your computer TeslaCrypt 4.0 Virus would start compiling a list of your most often used personal files. No system files would be affected by the ransomware as it wouldn’t want to hinder your system as to not make it harder for you to pay the demanded ransom. Important to note here is that in the new version TeslaCrypt 4.0 an important “bug” has been fixed. In the previous version any encrypted files bigger than 4 GBs were being corrupted and inadvertently lost. This has now been remedied giving even more flexibility to the criminals behind TeslaCrypt 4.0 Virus. Back to the topic at hand, once the list with your files has been sorted out then the actual encryption operation would begin. It is important to point out that this new version of the ransomware is even “greedier” and allows the criminals to attack and encrypt more of your personal information than ever before. Also it now runs the RSA-4096 algorithm for encryption of data, thus making it almost unbreakable as far as cracking the encryption goes. Once your files have been replaced with encrypted copies your options are limited. According to the ransom note you would have to pay in bitcoins for a decryption key, somewhere in the range of $150 to $1000 depending on the amount of encrypted data. This is obviously a very steep price so let’s get right to the important question that has probably been troubling you.

If TeslaCrypt 4.0 Virus is that bad should I actually pay the ransom?

We firmly believe this is entirely up to you and no one should make that choice instead of you. But we can share our strong opinion on the matter. You should definitely not pay any ransom. There are a number of reasons for our stance but we will list only the major ones.

  • We did mention that it might very well cost you a cool $1000 to get a decryption key. You should seriously ask yourself if this is really worth it, even if your files are important to you. We realize this might be a hard thing to measure up, so let’s assume that you feel it might be ok to pay such a hefty sum.
  • There’s absolutely no reason to believe that the people behind the TeslaCrypt 4.0 Virus will keep their end of the bargain. Even if you pay the demanded ransom there are no guarantees that you will actually receive a decryption key. On the contrary there are numerous reports about people being ripped off once more after paying a ransom. Never forget that you are actually dealing with cyber criminals here, you should not trust anything that comes out of their end.
  • Speaking of the criminals behind TeslaCrypt we would really like to make a point about how important it is to stop these people. The only way for that to happen is for the affected users to refuse to pay any and all ransom payments. This is the only way to hamstring the ransomware revenue stream. A “business” that has turned into a million dollar industry and shows no signs of slowing down. Quite the opposite – new and more elaborate versions of ransomware applications are coming out ever more frequent.
