  • Scanning Icon
    Deep Threat Scanning
    With one of the most extensive virus and malware databases in the industry, STOPzilla scans deeper and more thoroughly than other security products. It finds and eliminates many threats that other products in the industry fail to detect.

  • Safe Icon
    Application Hardening
    Many viruses and malware threats are designed to interfere with the operation of AntiVirus/AntiMalware products. STOPzilla AntiVirus is designed to thwart this type of interference allowing the product to install and provide uninterrupted protection.
  • Anti-Rootkit Icon
    Anti-Rootkit Technology
    Rootkits avoid normal methods of detection by placing themselves between the operating system and the AntiVirus/AntiMalware software. STOPzilla AntiVirus recognizes rootkits before they can infect your computer and eliminates them.

STOPzilla uses proprietary AntiVirus Technology to make this antivirus program one of the most secure and resource-friendly products on the market. It's also one of the rare antivirus programs that is entirely developed and supported in the United States.

STOPzilla has powerful anti-rootkit technology. Rootkits are among the most difficult types of malicious software because they actively subvert standard antivirus programs and even certain anti-rootkit programs — allowing them to continue draining available memory and run unauthorized processes. With Anti-Rootkit Technology, STOPzilla AntiVirus recognizes rootkits and eliminates them before they can infect your computer.

Customer Reviews

5 / 5
Saved my PC

I'm a lifetime subscriber, for two very good reasons. One -- Stopzilla is a comprehensive, accurate/thorough/ antivirus MACHINE. Two -- this awesome utility saved my computer from a very pervasive and destructive virus (not to mention: yucky! pirated my browser to some very 'questionable' sites. :( ). Nothing else would touch that virus, others like a certain Windows product and another one that starts with an A, wouldn't even recognize that anything bad was on the computer! Stopzilla saved the day, and I've been a dedicated user ever since. Thanks for a GREAT product!

Yes I would recommend
