Hello Hussein,
We will help you to sort it out. Please click here for the instruction to install AVG Internet Security on your computer (if you have uninstalled it).
Configure your AVG Firewall settings, please change AVG Firewall network profile to private (open AVG Internet Security > menu > settings > components > firewall > customize > network profile > change all the network public to private), go to Firewall customize settings again > scroll down > click on system rules > enable all the system rules if it's not configured, click OK and check if you can access all the application with enabled AVG Internet Security.
If not, open AVG Internet Security > hacker protection > open ransomware > allow/blocked apps > look for Microsoft office and allow it.
Keep us informed about the status.

Hello there, I would be grateful for any assistance. After installing AVG Internet Security multiple applications failed to start. Please include Microsoft Outlook, Microsoft Word, one Drive, rescue time and others. They all start with errors saying that the application is unable to start. Uninstalling AVG Internet Security immediately resolve the problem. I would be grateful to have this fixed as I have a paid licence until 2021. Also please note that I am registered blind and use a screen reader. Thanks in advance for any help to get this fixed.

Hello there, thanks very much for taking the time to get in touch. Unfortunately I now cannot open AVG Internet Security at all as I received the same error code 0x c0000005. I will have to try uninstalling and reinstalling the application to see if I can then get into the main settings.

 
I will be grateful for any further suggestions on how this issue can be resolved. Thanks as always for your time and support.
