SysWatch Personal is designed to work alongside - or even replace - Microsoft Security Essentials and other signature-based security software to provide comprehensive protection for your computer. It does this by combining whitelisting, sandboxing, and behavioral analysis techniques to keep malware and intruders out - automatically. What's more, you don't lose system performance to resource-intensive scanning activities. Once you've created your system profile and trusted application register, SysWatch automatically detects and prevents unknown code (which all malware is) from executing on your PC, protecting your entire system. SysWatch Personal protects your computer proactively by controlling how applications behave. It keeps your whole system in a 'known-good' state, preventing hacker attacks and malicious software from activating. Because SysWatch Personal does not need to identify individual threats in order to block them, it doesn't need all those signature updates required by traditional security software to provide reliable protection. While you don't need to run a traditional antivirus program as well as SysWatch, you may feel more comfortable doing so until you have gained full trust in the SysWatch approach to computer security. SysWatch is fully compatible with all popular antivirus programs.
