How to uninstall Avast antivirus ?
As most PC users know, Avast is one of the best free antivirus programs for Windows. Although it is quite useful software, in some cases, it can interfere with another program, or can even be installed as a bundle without the need for it. Regardless of a reason, we’d like to continue our user tips series with how to uninstall Avast completely and leave no residues.
In fact, there are two ways to remove Avast products (antivirus, VPN, browser, driver updater, etc.): manually and via special 3-rd party software. The first way is conventional and reliable. Uninstallers such as Wise, Revo, Geek, and other best uninstallers though, offer simplicity and competent cleanout. We’re going to describe step one has to take to say goodbye to Avast. Also, it is worth noting that the uninstalling process is the same for Windows 10, 8 and 7.
Step 1: Open Avast program on your PC, find the Menu button at the user interface and click it. Then go to Settings in the drop-down menu.
Step 2: In the Settings window, select General tab and then Troubleshooting tab from the sub-menu. Turn Self-Defense mode off by deselecting the checkbox.
Step 3: When a warning message appears about the attempt to disable the Avast self-defense module. Go ahead and click OK. Close Avast antivirus.

Step 6: The configuration screen will offer to confirm the action, press it. The process begins and might take several minutes, as it should delete all of the Avast files distributed throughout the system.
Step 7: As the process completes, Avast Setup will ask to restart the computer.
That was the first, and the most typical way to uninstall Avast antivirus and its components. If this method seems complex or you want to do it faster, there are other options at hand. There is a special utility, Avastclear, to delete Avast applications correctly.
