This page aims to help you remove .Betta Ransomware for free. Our instructions also cover how any .Betta file can be recovered.

A Ransomware cryptovirus is something you really don’t want to get inside your computer, especially if there are a lot of important and valuable files on your PC that you don’t want to lose. The reason for that has to do with the way this particular category of malware functions. Once a cryptovirus infection manages to get inside a given computer, it initiates a complex encryption process that ultimately makes all targeted data files on the computer inaccessible because they get locked by the sophisticated encryption code used by the virus. Of course, the idea behind that is so that the users would then get blackmailed and harassed into making ransom payments to the hackers that have invaded their PCs. Supposedly, if the money requested by the hackers is paid by the users, a unique decryption key would get send to the malware victims and they would thus be able to regain the access to their personal data. This, however, is not guaranteed to happen in all instances where users agree to pay the ransom sum requested by a given cryptovirus infection.

Oftentimes, the hackers “forget” to send back the decryption key and it’s also possible that sometimes the key itself doesn’t really work as intended. In either of those cases, the users’ money is simply wasted in vain as the files remain locked and the money is long gone in the hackers’ hands. This is not to say that paying the ransom would never yield the expected (and intended) results but going for that course of action in case of a Ransomware cryptovirus attack is still risky as you could simple lose your money without actually gaining a way of recovering your locked-up data.

How to Decrypt .Betta files

We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here.

The .Betta cryptovirus

One of the more recent representatives of this particular malware type is a nasty and malicious threat that goes under the name of .Betta. This highly-problematic virus is possibly the reason why most of you have landed on this page. .Betta is currently very widespread and there are indeed many users out there who have already gotten their data locked by it. If you are one of the many victims of .Betta and don’t know what to do now, we advise you to take a look and make use of the following removal guide:

There are, however, several things we must point out here. First and foremost, regardless of whether you go for the removal guide from this page (or for some other alternative) or decide to make the requested ransom payment, there would usually be no guarantees that you’d actually be able to get all of your files back. The guide we offer you can help you remove the virus, yes, but the restoration of the files requires additional steps and methods. Such steps/methods can be found in a separate section of the removal guide for .Betta but we can’t promise that they’d work in all instances. That said, as mentioned earlier, paying the ransom also doesn’t guarantee that your data would get restored as the hackers might simply decide not to keep their promise of sending you the decryption details. In the end, you are the one who must decide what course of action would be the most practical and optimal in your specific case.

Detecting Ransomware

Normally, it’s really difficult to spot a Ransomware threat like .Betta on time since it doesn’t really show all that many symptoms. In fact, even your antivirus is quite likely to fail at spotting such a threat. Usually, the only somewhat visible symptoms that can be expected during the encryption process are increased use of system resources like HDD space, processor time and RAM memory. After the process is finished and the targeted files are no longer accessible, a note gets displayed on the user’s screen through which the malware victim is informed that they need to make a ransom payment to get their files back and there are detailed instructions on exactly how to make the money transfer.

Maintaining a safe PC and files

The best you could do against a potential future Ransomware attack is back-up your files and store them in a safe location (an external HDD, a flash-memory stick, a cloud, etc.). Still, thought this should be enough to keep your data safe, you must still try to keep your machine clean by avoiding shady sites, not opening questionable ads or messages and also by only downloading stuff from reputed sources and developers. Remember that pirated software is one of the most likely sources of malware so make sure to keep away from such downloads.
