CryptorBit virus Removal Guide

What is CryptorBit virus?

What is known about CryptorBit virus?

CryptorBit virus is a dangerous ransomware program, which can easily affect Windows OS. It is believed that this ransomware is closely related to Cryptolocker which has already infected thousands of PC users. As soon as it enters the computer, the cyber threat looks for specific files (Microsoft Office files, PDF files and picture type files) to encrypt them. Also, it starts displaying a huge pop-up notification which provides a step-by-step guide explaining the whole decryption process. Typically, it requires visiting a specific payment site and sending a 500 dollar ransom in Bitcoins for its creators. Please, ignore all alerts saying that “your personal files are encrypted” because they are used for the only thing – supporting hackers and increasing their profits. If you are infected, you should waste no time and check your computer with reputable anti-spyware, such as FortectIntego. This is the only way to remove CryptorBit ransomware from the system.

After being discovered in 2014, a new version of CryptorBit was noticed in July 2016. This time, ransomware requires paying 2 Bitcoins (or $850) in exchange for its decrypter. The amount of money which is required by this virus has almost doubled making, so there is no surprise that security researchers have started calling it “greedy”. Also, it has been discovered that this virus relies on both, AES and RSA encryption algorithms, while to encrypt personal files of the victim. At the moment of writing, it can encrypt 96 file types, but it is believed that this number will increase. According to PandaLabs, this ransomware can be decryptable, but there is no CryptorBit decrypter available on the Internet yet. The only thing that we can recommend is to back up your data and keep a reliable anti-spyware on your computer. Also, make sure that it is up-to-date.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
