Comodo Firewall is a recommended application that blocks access to the Internet (incoming and outgoing) attempted by unauthorized applications to do so, preventing Trojans or any other malware or spyware from sending any kind of information.
Every time a program tries to connect to the Internet, the firewall asks if it should be given access, and if it is a program that can be trusted, it can be authorized and Comodo will remember that choice. It can be configured to block access and modification in certain folders.
The virus definition is updated automatically online, so you can be sure to be protected against the latest spyware or viruses.
