Repairing the Avast browser application is the second solution to the Avast problem. To enter the Settings app, click the gear-shaped icon in the lower-left corner of the Start menu. Go to Apps and select it. You should immediately open a list of all the applications and utilities you have installed on your PC, so be patient while it loads. In Control Panel or Settings, look for Avast and click Edit.
To repair it, follow the instructions given below:
- Run Avast, click the Avast icon in the system tray or the Avast shortcut on the desktop.
- To continue, click the menu button in the right corner after entering the main screen.
- After that, go to Settings.
- To continue, go to the Troubleshooting tab and then select the Repair app.
3. Use The Admin Permission On Avast:
This method is similar to the first one. But, you don’t need to go deep with services and such. All you need to do is launch Avast as an administrator. For this, you can ensure the following:
- Find the Avast launch icon on your PC. This can be a shortcut through the Start menu or elsewhere. Right-click on it and select ‘Run as administrator’.
- This will not work if Avast is already running in the background. So press CTRL + Shift + ESC to open Task Manager. Find Avast in the list of tasks and right-click on it. Then, select End Task.
- Now, repeat the first step and see if you can start Avast as an administrator.
- Once you’ve done that, reactivate Web Shield. See if this option works.
- You can also grant Avast Admin permission permanently. All you have to do is right-click on the Avast icon and go to Properties. You will find the ‘Run this program as admin’ option in the compatibility tab. Check it, Apply, and then OK to save the changes.
- Now Avast always runs with admin permissions. This can save you from other errors.
