There’s the Free version of Avast and there is now also a free version of Avast for Business.

Don’t know exactly what you mean by providing to open source projects. ???
If you mean in a business environment then the answer is “no”, at least not for free.
You may need to purchase a license…
For business see https://www.avast.com/business
Or a paid product see https://www.avast.com/compare-antivirus (note: the free version is for personal use only).
Or you can contact avast directly by using this form https://www.avast.com/contact-form.php
You need to make yourself familiar with Avast for Business. It is free provided there are less than 100 stations. 
It also depends if one wants in-house protection or in the cloud protection.
