VCatch is using an Advanced Malicious Application Detection system (called 'APayya'), which scans every incoming file looking for suspicious characteristics using a very sophisticated and flexible rules system. vCatch enables you to set the preferred security level and uses these settings when a suspicious file is detected in order to decide whether to notify you. This way you can be sure you are protected both from known viruses and from unknown malicious applications. The inovative techniques vCatch is using and the fact that it has no conflicts with other antivirus programs makes it a great security product that will improve your computer security even if you have another antivirus installed.
