Whats the difference between a firewall and a anti virus system? |
[Edit] |
A simple firewall like the Windows Firewall in XP and Vista protects you from outside attack by making your computer's ports invisible to outsiders and by refusing to accept incoming data packets that were not requested. Third-party personal firewalls also control which programs can use your Internet connection to contact sites outside your computer - so they offer two-way protection.
An antivirus utility scans the files and Registry on your computer to detect and remove viruses and other malicious software. Its realtime component prevents malicious programs from installing or launching in the first place.
The two are quite different and both necessary.
