If you’re looking for an antivirus that is light on memory during idle and scanning, here are the top antivirus that you might find useful for your slow computer. Remember, light doesn’t mean better detection rate, vice versa, heavy on memory usage doesn’t mean it is a good antivirus either.
The best antivirus is the one you feel most comfortable in, the one that allows you to play Dota or Diablo without lagging it. Then again, in today’s ample computing world, lagging is mostly due to your broadband internet speed.
For your information, Norton may not be the fastest but it is still one of my favorites. With today’s computing power, processing consumption used by most anti-viruses is not an issue. However, if you are on a very old and sluggish system, selecting an antivirus with the least taxing on the system is a must.
Below is the complete list of some of the most popular antivirus and its usage on system resources. The table does not include detection rate and features. For those in the dark, some antivirus has a ‘gaming mode’ where it will reduce the resources required when you are playing Dota or Counter Strike.
