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 Reimage Reimage Cleaner Intego 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.

Questions about CryptoHost virus

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.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
