The main reason for performance testing antivirus products is that not all antivirus packages are created equal when it comes to providing PC and web browsing protection, memory usage, background scanning speeds, virus detection and removal, etc.
Antivirus suites should have at least the following modules:
Online Antivirus Scan
If you do not have any antivirus software currently installed on your PC and you have been surfing the web, then I strongly suggest you scan your system with an online antivirus scanner before you download and install any trial antivirus suites.
Installed Antivirus Software
If you currently have any antivirus software already installed on your system then this must first be uninstalled completely and your system restarted before installing any trial antivirus packages.
Recommended Uninstaller Program
After you have downloaded and installed Revo Uninstaller, use it to uninstall your current antivirus program. If for some reason, when you go to install an antivirus trial and it will not install due to some leftover files from the previous antivirus program then download the previous installed antivirus programs removal utility from the vendor's web site and run it.
N.B. Restart your computer after you have uninstalled the antivirus program.
System Resource Usage
How to Check System Resource Usage
This screen shows memory and CPU usage of your computer.
Once you have noted the memory and CPU usage without the trial software installed on your system you can now go ahead and install the trial antivirus package.
You then need to run a full antivirus scan of your system and repeat the memory and CPU check while the antivirus scan is running. Again, note the memory and CPU usage.
Once you have completed your testing of the first antivirus trial suite, uninstall it as per the instructions above with the Revo Uninstaller program and repeat the testing process for the other antivirus trial suite software you have downloaded.
If your PC performed badly with all of the antivirus trial software, the memory cannot be upgraded and you ran the Advanced System Care before testing the trial software then your system may require a re-installation of the operating system.
The need for antivirus protection is of paramount concern for virtually all PC users.
First Things First: What IS a Computer Virus?
A computer virus is just one of three types of programs known as "maliceware". Most antivirus programs are designed to detect and defend your PC from all three threats.
What Does an Antivirus Program Do?
Antivirus programs take two common approaches to recognize threats to your computer.
1. Signature Detection: Via Signature Detection an antivirus application scans your computer, drives and storage devices for files that contain a code it recognizes as a virus variant.
Antivirus applications that scan for potential computer virus activity can be more useful at detecting the latest threats than those reliant on signature detection. Most of today's "solid" antivirus programs utilize a combination of both signature detection and virus activity to protect your computer against threats.
How to Choose the Antivirus Program that is Right for You.
Risk generally equates to your computers exposure to outside applications, files or connections. If you were to operate a computer that would never come into contact with any program or file not manufactured by a secure source, then you have virtually no need for an Antivirus application. There are many good antivirus programs that will fit this need available as shareware - a free download - throughout the internet.
Antivirus software manufactured for business and home can be two very different applications both in cost and effectiveness. Home versions generally cost less and come with fewer options than business based antivirus programs. Most corporate versions of antivirus applications allow for a central point of control over entire networks. Protection can be divided between internet or application servers and individual PCs. Exchange/mail and internet server protection is a must, as well as protection for mission-critical file and application servers. Usually business antivirus programs come as a server based application. Clients, or additional licenses, are purchased for each computer or user that connects to the antivirus server.
With Regard to the Antivirus Program Itself:
The best antivirus manufacturers release updates on a daily basis and often offer updates to their programs on a real-time, as needed basis. The ability for an antivirus software manufacturer to release constant, and relevant, updates to their programs should be of great concern to the user. - Just like all applications and operating systems, antivirus applications will use your computers processing power, memory and storage space to function.
