What MZGuard protects

Ransomware, credential theft and network attacks, watched in real time.

Antivirus relies on known signatures. MZGuard adds an IDS layer that looks at behavior: what a process does, what a script tries to run, and what leaves your PC on the network.

Ransomware protection

Detects ransomware-like file activity such as mass changes and rapid renames, and can interrupt it before encryption spreads.

Ransomware modules

Anti-keylogger and credential protection

Adds a protective layer against keyloggers, form-grabbers and clipboard hijacking, with user-confirmed actions.

Privacy modules

IDS and firewall monitoring

Watches network activity, shows the process, remote address and ports behind each connection, and enforces rules in Windows Firewall.

Questions

What people ask about MZGuard IDS.

More detail is in the full FAQ.

What is an Intrusion Detection System (IDS)?

An IDS monitors activity on a computer or network and raises alerts when behavior looks suspicious. MZGuard applies this approach to Windows endpoints, so it can react to behavior that signature-based tools may miss.

Does MZGuard replace my antivirus?

No. MZGuard is designed to work alongside your antivirus, adding behavior-based monitoring, anti-keylogger protection and firewall control.

Which Windows versions are supported?

Windows 7, Windows 10, Windows 11 and Windows Server.

Where can I see what MZGuard has blocked?

The security log records every block and allow decision, with the module involved, so you can review what happened and why.
