Antivirus Uninstaller Tools: 26 Best We Tested in 2023

Knowledgeable computer users will tell you it’s not the best idea to have more than one Antivirus or Internet security package running at the same time on your PC. They usually don’t like each other and can cause system instability, degrade performance and maybe even cause viruses not to be identified correctly. There are a few reported applications that work together with their real time protection running, but for the most part, it’s a bad idea. For this reason, it’s very important that any previously installed antivirus software is uninstalled from your system before proceeding with the installation of the next antivirus that you would like to install.

The possible exception is having one piece of software to do the main job of actively watching for the threats, and another software to act as an on demand second line of defense scanner to manually scan once in a while. Security software not removing itself completely before installing something else, either because or a poorly programmed uninstaller or a crash/hang during the uninstall process is a major cause of problems encountered when installing a new package.

It’s worth pointing out that programs like Revo Uninstaller, IOBit Uninstaller and Advanced Uninstaller Pro which do a good job of removing remnants left behind from a lot of of software, may be able to remove enough to stop any errors or crashes, but it’s no guarantee. If you have used a program like this to uninstall an Antivirus or Firewall and still have problems, then try one of the dedicated removal tools below.

1. AppRemover


AppRemover deserves a mention because it claims to remove several security applications from one single portable executable. Although it by no means supports the removal of all products listed here, there is still a lot that AppRemover can possibly remove. Visit the Supported Applications page for the full list.

While AppRemover does seem to generally do a good job, this is perhaps a tool to be used if you still have issues after trying an official removal tool because there could possibly be leftovers of other security software still causing a problem. The general consensus seems to be AppRemover is a useful tool to have, but results seems to be rather mixed after using it.
