Leitkcad Ransomware
A ransomware infection dubbed Leitkcad has been detected in active attack campaigns. This threat is developed to infect computer operating systems by installing malicious files without generating any notifications. Its presence on an infected PC can be noticed at the end of its attack – when it is too late for taking some prevention steps. The moment its ransom message (help-leitkcad.txt) appears somewhere on the system, it means that the ransomware has successfully encrypted your personal files and renamed their names with the .leitkcad extension. Since ransomware infections like Leitkcad tend to use complex cipher algorithms for data encryption, these programs leave files completely inaccessible.
Even though hackers insist on paying them a hefty ransom fee, we advise you to avoid following their instructions and try to remove malicious files from the infected PC with the guide that follows.
