CryptXXX 3.0 Ransomware Removal

Welcome to our CryptXXX 3.0 removal instructions. This article intends to help you remove CryptXXX 3.0 from your system and is designed to work for all Windows versions.

Ransomware is one of the most horrible instances of malware infection. Not only is it incredibly violating to have your intellectual property trespassed on (because that’s exactly what this is), but it can also result in permanent loss of your files. Unfortunately, CryptXXX 3.0 is exactly one of these awful viruses, but don’t be dismayed. This guide is designed to show exactly how to remove it from your computer and we will even show you how to decrypt your files. Now, while there’s no 100% guarantee that our decryption method is going to work absolutely flawlessly and it will decrypt each one of the encrypted files, we still recommend you try it first before resorting to more drastic measures, like paying ransom for example. By the very least, our instructions will not harm your files.

You probably found out about CryptXXX 3.0 when it had already done its dirty deed and then surprised you with a message on your screen, telling you no longer have access to certain data on your PC. In addition to this, it probably also demanded ransom within a given time frame, which is even more stressful and aggravating. This is a scare-tactic and you shouldn’t fall for it. We will break this down in just a little bit and tell you all you need to know about CryptXXX 3.0, including how to protect yourself from it in the future.

How does CryptXXX 3.0 operate exactly?

Like most ransomware, CryptXXX 3.0 will typically require the help of a Trojan horse in order to access your computer. The Trojan will in turn most likely be sent to you via email and the message will include either an innocent-seeming attachment or a link to some website. If you open the attachment or click the link, you will unleash the Trojan and it will proceed to automatically download the ransomware. Obviously, your permission won’t be requested and chances are you won’t even suspect anything. There is, however, a slight probability that you might notice something’s wrong and this will depend on your computer’s processor and the amount of files stored on it. If it’s not the fastest running machine and the data is pretty substantial, then your PC could start working slower than usual and this is what should raise a big red flag. This is due to the fact that once the ransomware begins encrypting your files, it will take up a huge amount of RAM. To determine whether you are indeed infected, go to the Task Manager and search for the processes using the most memory. Notice a process that shouldn’t be there? Shut down your system immediately and seek professional assistance.

Most times, however, users aren’t that lucky and only find out about CryptXXX 3.0 with the message described above. In this case you will in truth not be able to access the encrypted files and the hackers will hope that you’ll panic and send them the requested amount. A few things to consider before doing that:

  • Crypto currencies. Chances are the ransom will be asked for in Bitcoins or another cryptocurrency, which is very difficult to trace. Would you really want to encourage these guys to continue doing what they’re doing by ensuring they won’t get caught?
  • What exactly makes you think that once you’ve sent some common criminals money, they will send you the decryption key? You are basically blindly trusting them to do so with no guarantees whatsoever.
  • Decryption failure. Yup, even though it’s their key, there are again no guarantees that it will work. Just like with our solution, only in our case we’re not charging you anything.

Security tips

Of course, it’s not our place to tell you whether to pay ransom or not – that is totally up to you. But since you’re here, you might want to try an alternative solution anyway, so we recommend you follow the below steps first. As for staying safe in the future and preventing a mess like this from happening again, first and foremost is to be cautious with received emails. Especially those that land in your spam folder. If you see an email from some unknown source and it has an attached file in it, it’s best you don’t open it. And since ransomware can also be distributed via program bundles or malvertisements, we also advise you to stay far, far away from websites that are likely to have those. These include open-source download platforms, some torrent sites and other such potentially dangerous pages.
