What is Cylance Virus?

Once the encryption is done, Cylance File Virus will add its own malicious extension to the end of all your files. This new file extension is the mark of encryption and you will need the decryption key to unlock those files. This dubious threat will also leave a ransom note on your computer demanding money in return for the decoder. The note contains instructions about the payment and clearly says that there is no other method to unlock those files without the decryption key. The primary motive of Cylance Virus Ransomware is to frustrate victims and force them to pay extortion fees without seeking any help. However, there are other alternative methods to recover data without paying money to hackers.

  • Always keep your Windows firewall active, and your OS updated along with other important programs. Only download updates from official sites or reliable sources.
  • Check HTTPS before entering your email, password, credit card details, etc. to any site. Do not visit sites that do not have SSL security. Also, don’t forget to Enable Phishing and Malware protection in Browser.
  • Do not download or install any type of pirated software, games, or illegal patches. Avoid using shady sites to acquire freeware programs because they often use software bundling. Never install a program that asks you to inactivate your anti-virus software.
  • Avoid opening spam emails from unknown senders.  Always scan all the email attachments before opening them. Never click on any suspicious links with some too good to be true offers.
  • Connecting your PC or mobile devices to unsafe public Wi-Fi is not a good idea. You can also avoid unwanted threats coming from malicious sites by using a VPN to spoof your connection.
  • Keep regular backups of all your important data on external hard drives or cloud drives to avoid data loss in case of a ransomware attack. Also, create a system restore point on your system for security purposes.
