A1RunGuard is a free bulletproof blocker for unwanted programs + password protecting any executable + additional Anti-Ransomware protection.

A1RunGuard can prevent some Ransomware attacks. Ransomware often uses legitimate programs that may be found across all Windows versions for various destructive operations. This technique allows ransomware to avoid detection by the antivirus software. A1RunGuard intercepts the launch of these programs, but instead of completely blocking them, it investigates the command lines of the program and fires the alarm only if a dangerous combination occurs.

A1RunGuard can protect any executable file from running by a password. It allows specifying the main password or a special password for each program. A1RunGuard can block any unwanted process by the file name or the full path. A1RunGuard does not slow down the overall performance of a computer. It does not install system drivers, does not use real-time monitoring, not change the system files.
