What's inside

Layered defense, designed for real households

Six modules work together quietly in the background. You'll only ever hear from MenHerr when it has something useful to say.

Real-time malware shield

Behavioral and signature scanning catches viruses, trojans, spyware, worms and rootkits the moment they touch your disk.

Anti-phishing browsing

Our URL classifier checks every link against a 4.2 million entry blocklist updated every 90 seconds.

Identity monitoring

We watch dark-web markets for your email, phone or SSN and alert you within 30 minutes of a leak.

Ransomware vault

Critical folders are sandboxed and versioned. If anything tries to encrypt them, the change is rolled back automatically.

Smart firewall

Per-application rules with a learning mode that quietly blocks suspicious outbound connections.

Family controls

Optional content filters, daily screen-time caps and a parent dashboard you can review on any device.

Why we exist

An antivirus made by people who answer the phone.

MenHerr was started in 2017 by Donald Nguyen, a former network technician who got tired of watching neighbors and small business owners get burned by aggressive subscription antivirus brands. We are a small Salinas-based team — you can call us, and a real person will pick up.

A note from the founder

"The big antivirus brands have forgotten that security is a service, not a billing relationship. We charge a fair price, we explain what we do, and we don't bury cancellation behind five screens."

"I'm 71 and I've been through five antivirus brands. MenHerr is the first one that doesn't try to sell me something every time I open it."

"We protect 14 laptops at our accounting office for less than what we used to pay one of the big-name vendors. The dashboard is genuinely simple."

"Caught a phishing page my bank's own filter missed. Support called me back in under ten minutes when I had a question about the firewall."
