1. Turn Off/Disable Avast Completely (All Shields)

Turning off all Avast shields basically means completely turning off the whole Avast Antivirus active protection. So be sure you know what you’re doing, although it’s actually quite simple.

Step #1 – Just navigate to the Windows taskbar and find the orange Avast icon. By default it is hidden in some Windows systems, so click on the top arrow if you don’t see it. Once you find the icon, perform a right-click on it, look for the option ‘Avast shields control‘, and select one of the options there – disable for a) 10 minutes; b) 1 hour; c) until computer restart; d) permanently.

Step #2 – Whatever option you will choose, Avast will ask you for a confirmation, which you have to confirm by selecting ‘Yes‘. And that’s it, Avast and all its shields should be disabled/paused for whatever time period you have selected.

2. Turn Off/Disable Avast Temporarily (Specific Shield(s))

Besides turning off all shields at once, Avast also offers an option to temporarily turn off/pause any specific shield. Again, be sure you know what and why you’re doing it.

Step #1 – If so, then open the main Avast user interface, and go to Protection » Core Shields. Alternatively, you can go to Settings (in the bottom left corner in the main Avast interface) » ‘Components’ (or ‘Active Protection‘ in the older version). There you will see all Avast shields (File System Shield, Behavior Shield, Mail Shield, Web Shield) listed.
