Questions about JS.Crypto Ransomware

Regarding other performances of JS.Crypto virus, it seems to be similar to other ransomware type computer infections. Once it reaches a target system, it is installed to %Temp% and %AppData%\Microsoft\Windows\Start Menu\Programs\Startup directories and injected into Windows startup (ChromeService.lnk). Besides, to protect itself from being identified and removed easily, it creates files like chrome.exe, ffmpegsumo.dll, s.exe, msgbox.vbs, u.vbs, rundll32.exe, and many others. At the same time, JS.Crypto ransomware performs file encryption, which is why you may lose access to files having .jpeg, .mp3, .mpeg, .dot, .jpg, .pmd, .mp4, .sdf, .docx, .ppj, .3gp, .aet, and other extensions. On top of that, you may receive an alert claiming:

ALL YOUR PERSONAL FILES HAS BEEN ENCRYPTED

All your data (photos, documents, databases, etc.) have been encrypted with a private and unique key generated for this computer. This means that you will not be able to access your files anymore until they are decrypted. The private key is stored in our servers and the only way to receive your key to decrypt your files is making a payment.

As we have already pointed out, to decrypt files that have been jeopardized by JS.Crypto malware, you will have to pay the ransom. For now, the amount of money required is not big if compared to other ransomware infections. The required ransom is 0.1 Bitcoins (approximately $35) that has to be paid within four days. After that, the sum of money will increase twice or more. If you have already lost access to personal files and received JS.Crypto ransomware notification, you should remove JS.Crypto ransomware using ReimageIntego or another professional anti-malware and then use file backups. In case you have never done backups, and then you may be in serious trouble because there is no tool for restoring files except paying the ransom. However, before paying the money, think twice because you may disclose your credit card details and other sensitive information to suspicious parties that may later initiate thefts straight from your bank account.

How this ransomware infects operating systems?

There are several means through which JS.Crypto virus is spread. It may be injected into fake software update prompts (Java, Media Player, VLC player, etc.), spam email attachments, suspicious third-party software, torrent files, and so on. That’s why it’s vital to stay away from questionable content. In most of the cases, people get tricked into installing JS.Crypto virus through spam email informing about missing payments, pre-paid purchases, taxes, and similar issues. Therefore, be careful and if you find the typo, grammar or other mistakes in the title or content of the message, do not open its attachment. Besides, to keep your PC virus free, install a professional anti-malware and keep it up-to-date. It will block infiltration of dangerous/potentially unwanted programs and keep your PC’s stability.

If, unfortunately, JS.Crypto ransomware is already lurking in your machine, make sure that you delete it ASAP. To find out more about JS.Crypto removal, go to the page 2.

Protect your privacy – employ a VPN

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

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.
