Essentially, firewall protection and antivirus software combined together in a bundle is what is referred to as antivirus firewall software.
What is Firewall?
Protecting a computer needs two approaches. First is to not let suspicious programs access the hard disk or the RAM or not let the users access such known networks or sites. This protection is delivered by a Firewall.
A firewall is programmed to block access to any suspicious application. It can be programmed such as the ones that you find at work. If you cannot access certain sites from your work, it is because of firewalls and this is their specialty. They can let permitted communication flow seamlessly across the network while block others.
How Anti-Virus Firewall Software Work
You need anti-virus program for cases when your computer is already infected. Viruses may circumvent a Firewall by disguising themselves as good software or when Firewall is off. In such cases, one needs antivirus programs to take care of these notorious evils.
Spyware program, on the other hand, look to delete or stop the functioning of spyware programs, which are made to spy on your passwords, browsing habits et al.
These three components combined together are what make antivirus firewall software. They collectively work towards ensuring that your computer is protected from visible as well as disguised threats by using different technologies such as signature identification, heuristic or emulation techniques. While defining them is beyond the scope of this article, collectively these three software ensure that each file coming or going out from your PC is scanned for suspicious signs and you are warned of it.
While looking for any antivirus firewall software look for how individual module perform. If possible look for demo versions that can let you test the software before you make a buying decision. Compare each module as it is a stand-alone application.
Few things that you MUST factor are:
- Anti-virus module MUST offer real time protection
- Firewall should be easy to set up and use
- Spyware should work in real time and effective in deleting even the latest malicious programs
- Antivirus and spyware module should have regular updates and a known community
While free software can give you protection from basic viruses and threats, it is paid antivirus firewall software that you need while looking for serious protection; so compare wisely and stay protected.
