System Resource Usage

The most crucial factor to take into account when evaluating any antivirus suites is what amount of computer memory it consumes while running in the background and/or running scheduled scans, since it will be one of the main elements in your decision to purchase.

So, prior to downloading any software trial,, you must be aware of and record the amount of memory and CPU resources are currently utilized on your system, so that you can compare it with the memory and CPU utilization of the trial antivirus software.

How to Check System Resource Usage

Go to"the "performance" tab within "windows task manager". This will display the how much memory and CPU is used by your PC.

After you've analyzed the amount of memory and CPU use without trial software on your system, you are able to proceed to set up the trial antivirus program.

Once it is installed and restarted your computer, you will need to repeat the test of CPU and memory to determine the amount of memory and CPU resources are being utilized for the free antivirus program.

It is then time to conduct a complete antivirus scan on your system. Repeat the CPU and memory checks when an antivirus scanner is in progress. Note the amount of memory and CPU used.

If the scanning is running, you can open and close some programs and observe what your computer does. Write a notepad entry and then note the response time. The system may be slower than normal because of the file scanning , but it will still function with a respectable delay.

After the scan of your file has completed, you can repeat the process of closing and opening applications and using notepad to type in the text. These tests will function in a normal manner and without delays.

Once you've completed your test it is now time to make an informed choice about which antivirus suites will work best for your computer. If you're using an antivirus program but it's affecting the performance of your computer, you're left with two options, add more memory (that is if the RAM is able to be upgraded) or opt for a different antivirus program that doesn't interfere with the performance of your PC.
