Bidirectional Firewall

Today’s best antivirus software and Internet security software has a built-in (or optional) software firewall.
A good firewall should have the ability to monitor Internet traffic in both directions: incoming and outgoing.
If there’s some unexplained traffic activity you should receive a warning, and the software will block it if it’s from a suspect source, giving you the chance to see what’s going on and allow the connection or block it.
This is particularly important if you have a high speed Internet connection that’s always on because even if you don’t think you’re online, chances are you are, so you’re still be vulnerable to an attack.
This gives you a choice of scanning your PC as you see fit. With the scheduled option you can set the antivirus scan to run at a time and frequency of your choosing.
You can select daily, weekly or monthly scans and the time of day to run it. If your antivirus software uses a lot of system resources you may prefer to schedule it to run late at night or in the early a.m. hours so as not to slow down any tasks you are working on.
On demand scanning allows you to run it at anytime you desire, just click the appropriate button on the user interface.
