.Cryptohasyou virus Removal Guide

What is .Cryptohasyou virus?

Why should you beware of .Cryptohasyou virus?

.Cryptohasyou virus leaves no doubt that it is a dangerous virus and the one you should look out for. It comes from the ransomware branch of viruses including hundreds of virtually identical viruses such as Locky virus, Rokku and Petya. However, as some of the newer versions of the mentioned viruses have been improved to use JavaScript to run, .Cryptohasyou is still using Word Macros to activate itself. However, this by no means suggests that this virus is less dangerous. In fact, looking at other functionalities, it does not differ from more established and well-structured viruses.
.Cryptohasyou enters computers through infected email attachments. Once the downloaded file is opened it asks the user to enable Word Macros, if it is not yet enabled. It allows the virus to run a script and download an executive virus file. If you a see similar message, do not enable it! Otherwise, the virus will start scanning your computer for files and encrypting them using sophisticated AES-256 and RSA-2048 encryption codes, which are impossible to decrypt without special key. This key is of course, not accessible unless the victim pays a ransom to the virus creators. This virus may affect all sorts of files: video, audio files, pictures, documents and archives are among the main targets since they are usually of the most value to the victims.

YOUR_FILES_ARE_LOCKED.txt file added to every infected folder of the computer, after the encryption is executed. It states that the victim must pay $300 in order to retrieve the files. What is more, by every three days the sum is said to increase by $150. Of course, the money must be transferred in BitCoins, through an anonymous Tor network. However, even after paying the ransom, the victims cannot be entirely sure the access to their files will be granted. It is not uncommon for cyber criminals to simply disappear with files and the money as well. Therefore, it is not advisable to follow the ransomers’ conditions and to remove .Cryptohasyou from the computer as soon as you notice any of the signs this virus may have infected it. Use trustworthy anti-malware tools likeFortectIntego to speed up the whole removal process.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
