PC Tools Firewall Plus is another free PC Tools product designed to protect your computer from unwanted Internet or local network access to our computer. By monitoring incoming and outgoing calls, the program allows you to stop applications such as Trojan horses, keyloggers, malware before gaining access to the user's computer, extracting private data, and so on. PC Tools Firewall Plus is designed to be used by users with no specialist knowledge about blocking applications.

Another advantage of the application is the relatively small use of system resources during operation (about 6 MB) and the ability to define custom packet filtering rules.
