According there is nothing wrong with the antivirus software , you are trying to install in your computer.
there is surelly some issue with the windows( operaing system )
so to resolve this , open the Event viewer and under the system check for the Event id , after this try to seach for issue ,by event id
This will solve your issue .

You are saying that you system working fine without any antivirus. Does this any means that you are installing more than 1 antivirus in your system? If you already have 1 antivirus in your system and if you are trying to install Avast also, both antivirus may conflict with each other and both may not function. Ultimately, your PC will be affected. Use only 1 antivirus in your system.

If this is not the problem, then please correct me.

What deveritt said is correct. There should not be 2 antivirus running at a time. I suggest an installation from the scratch:

1. Uninstall avast from Control Panel first.
2. Boot.
3. Download the latest version of Avast Uninstall and use it for complete uninstallation.
4. Boot.
5. Install again the latest avast! version.
6. Boot.
7. Check and post the results.
