If you are having any issue at all getting your iPhone or iPad to connect via the USB cable to your computer and have AVAST Business CloudCare installed, try these steps as the AVAST CloudCare firewall could be blocking your device.
NOTE: This should be fixed with the latest Avast Business CloudCare version and you should not need to follow these instructions. If you are not sure if you have the latest Avast CloudCare version, please contact your Avast CloudCare support agent.
Now connect your iPhone or iPad as you normally would
After you have finished accessing your Apple iPhone or iPad, remember to switch the firewall back on by pressing Turn On or restarting your computer will also switch the Firewall back on.
