What is there to know about CryptoHost virus?
CryptoHost virus, also known as Ransom:MSIL/Manamecrypt.A and Ransom_CRYPTOHOST.A belongs to a very malicious branch of ransomware viruses. These viruses, including the well known programs such as Locky virus, CryptoWall or the Surprise virus enter the users’ computer unexpectedly, scan them for files and, when they find the necessary files, they lock them with a very complex algorithm. Such encryption techniques are used even in military, so the decryption of files encrypted by the ransomware virus is almost impossible. Of course, there have been cases, when the computer experts have come up with special decryptors and helped the victims to retrieve their files, but such cases are rare. In most cases, the victims simply have to face the fact that they have lost their files and remove the virus from the computer. Luckily, the CryptoHost does not actually encrypt the files but rather create a copy of the victim’s data in a password-protected RAR archive in the C:\Users\[username]\AppData\Roaming directory. The cyber security experts comfort the victims, that the password to these archives is relatively easy to discover, so it is most likely that the files are going to be retrieved as well. The password consists of RAR file name and logged in user’s username.
However, it is important to note that regardless of whether you manage to decrypt the locked documents or not, you should remove CryptoHost virus from your computer without a delay. Beware that even the most sophisticated software such as FortectIntego can struggle with the initial virus removal. So, you most probably will have to follow manual CryptoHost removal steps to lessen some of the program’s functionalities which should help your antivirus initiate.
As mentioned before, when CryptoHost infiltrates the victim’s computer, it scans it for files. The video, audio files, pictures, archives and other documents are the primary targets of this ransomware. Once the files are encrypted, the virus then adds a ransom note to the folders featuring infected files, in which the victim is demanded to pay 0.33 Bitcoins or $140 ransom to be able to retrieve them. Of course, it is not advisable to do, because as already mentioned, you can decrypt the files. Plus, would you want to support malicious program developers in this way? The best option in case you are infected is to try decrypting your data and remove CryptoHost from your computer immediately.
How can this virus infiltrate my PC?
Differently from the majority of other ransomware programs, CryptoHost does not spread through infected email attachments or exploit kits. It is said to be delivered through a new µTorrent client. This deceptive bundling strategy is also very popular among the less dangerous malware such as adware or browser hijackers. A potentially unwanted program is attached to the more popular software and stealthily installs along with it. The key to avoiding such covert installation is to use “Advanced” installation settings when installing software on your computer. These settings will allow you to monitor what additional programs are bundled with your downloaded software and help you to avoid unwanted and potentially dangerous contents from entering your computer. In case suspicious applications surface during the installation, terminate the process and delete the unreliable software bundle from your computer.
