There is a lot of misinformation in the marketplace about various antivirus firewall software products.
Much of this seems to stem from some of the companies that market these products and then degrade a competitors product without providing you with the full facts.
Quality antivirus firewall software should provide you with the most comprehensive internet security cover available, and as such is required to carry out a vast array of checks and scanning in your computer.
This puts increased pressure on the processing ability of your machine, especially at the critical start up phase.
Sure, you want to check your emails as quickly as possible when you get up in the morning, or check out a new website a friend told you about, but the chances are you will need to wait a few minutes or more before anything happens.
These few minutes can seem like a lifetime and cause the most criticism of a product. However its important to know what is actually happening at this time.
All information entering and exiting your computer needs to be scanned and checked against known threat profiles, whether they be viruses, keyloggers or other types of malicious software.
Therefore all emails need to be scanned thoroughly as these are often the first to be loaded.
Your antivirus firewall software acts like a control gate, where only approved data can come and go. This causes a bottleneck because of the volume of information trying to get through soon after start up.
If your software is a quality product, it generally scans files that were modified since the last scan, looking for any tell tale signs or threat profile matching against known problems.
Full system scans check all files, but many of these files are checked when the computer workload is low, such as at idle or when simple tasks are being undertaken.
The firewall is part of the software program and its role is to keep unauthorized access out while at the same time allowing authorized and approved communications.
All messages sent and received pass through the firewall, which then checks each one and stops those that don’t conform to the rules set up for the application.
Backing up your information is another important function which, in the case of future data loss, can become financially crippling. Automatic back up helps protect your files, even when the unthinkable happens.
Choosing the best a antivirus firewall software is important for your online security, now and for the years to come.
