STOPzilla uses proprietary AVM 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 AntiVirus can be used as a stand-alone computer security solution, or as a compliment to other security programs – thanks to its Shared Protection mode that allows it to work with other antivirus programs without causing any system errors. STOPzilla also 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.
