Outpost Firewall Pro delivers proactive defense against hackers, spyware, Trojans, botnets, keyloggers, ID theft and other Internet-borne threats. The integrated anti-spyware module defends against the broad range of malicious programs. Its on-demand scanner enables scanning custom locations, while the real-time monitor is constantly on guard against the activation of spyware. File checks complete much faster because the SmarScan2-driven engine examines only items altered since the last scan. The firewall's unique Attack Detection protects LANs against man-in-the-middle attacks and other sophisticated intrusions. The Host Protection module takes a new approach to combating malware: it pre-empts the infection by examining the behavior of a monitored object, proactively blocking it from performing any unauthorized activity. This type of defense-in-advance helps to halt unknown malware before it can activate its destructive payload.
