The process of completely uninstalling Avast antivirus is quite tricky. It has happened to me before. After uninstalling, it comes again in your system. Uninstalling it completely requires some tricky steps.
Step 1: Go to the bottom left corner and click on the windows icon to pop-up the ‘Start Menu’. Now, click on the small gear above the windows icon to open ‘Windows Settings’ tab. Now right click on Avast and click on uninstall Avast antivirus. Hope so your problem will be resolved.
