Disabling Avast’s Self-defense Mode For A Smoother Uninstallation Process

Manually Removing Avast’s Software Files And Registry Entries
When uninstalling Avast, you may encounter situations where the regular uninstallation process fails or leaves behind certain files and registry entries. To ensure a clean uninstallation, it may be necessary to manually remove these residual elements. However, please note that modifying the registry without proper knowledge can cause system instability, so proceed with caution and create a backup beforehand.
To manually remove Avast’s software files, begin by opening File Explorer and navigating to the Avast installation folder. Typically, this can be found in the “C:Program Files” or “C:Program Files (x86)” directory. Locate the Avast folder, right-click on it, and select “Delete” to remove it permanently.
Next, it’s essential to remove any remaining registry entries related to Avast. To access the Registry Editor, press Windows Key + R, type “regedit” in the Run dialog, and hit Enter. Within the Registry Editor, navigate to “HKEY_LOCAL_MACHINESOFTWAREAvast Software” and “HKEY_CURRENT_USERSOFTWAREAvast Software”. Delete these folders by right-clicking on them and selecting “Delete”.
Manually removing Avast’s software files and registry entries should allow for a complete uninstallation and help resolve any ‘Setup is Already Running’ issues you may have encountered.
