You’ve heard about Kaspersky Antivirus or Nod32. They protect your system from harmful intruders and corrupted data. If you don’t secure your system well, you are prone to attacks that can cause you a lot of trouble.

These antivirus programs are reliable and have a good reputation, but they also eat up a lot of your system’s resources. This can hamper your device’s performance, eat up your RAM, and cause everything to run slower.

Luckily, there are various reputable antivirus programs that are much lighter. Most of them are completely free and good enough to keep your home or small business network completely secured. This article will list the top five antivirus programs that will protect your computer without slowing it down.

1. AVG Antivirus


AVG is a free antivirus program that provides all the necessary solutions for your personal devices. You can install it on your personal computer, and there is a smartphone version as well.

This program will provide all the essential protection in its free version. It protects from viruses, malware, and spyware. It will check your downloads and warn you if any file is corrupted or infected with malicious software. If you try to visit any unsafe link, AVG will block it and notify you about the risks.
