Firewalls – Barrier Against Infiltrators
Windows Firewall filters data before it enters your system. Not only it checks incoming information; it takes care of outgoing information as well. A firewall that works with a router program probes every network packet to decide whether to forward it toward its address.
Windows Firewall protects the valuable data stored on your PC in following ways:
• Denying Remote Login
• Preventing SMTP session hijacking
• Scanning E-mail bombs that in most of the cases carry viruses
• Not allowing suspicious Macros to run on PC
• Keeping track of Virus, Spams and Trojans
• Deleting / blocking risk ware
