It seems that all of the computers in our Avast for Business is able to get forced updates/scans/tasks. However mine will always error. It states “The plug-in wasn’t found on device” whenever I create and run a task for all of the computer to get an update/scan for viri, etc.
HI,
Uninstall from the device and run this cleaner utility https://www.avast.com/en-us/uninstall-utility then reinstall.
Post back and let us know if this helped or if you still have issues.
