I want to contact A vast the anti virus company.

Hello, Ken -

This is the link to the home page for Avast:
https://www.avast.com/en-us/index#pc

Scroll to the bottom of that web page. In the lower right corner of the home page you should see a column headed with "The Company." In that column, you should find the Contact Us link. Click or tap on that link.

You will have a choice between Customer Support and Business Support. At the bottom of that page you will also see other links. Make the choice which is most relevant to you and follow the on screen instructions.

Best wishes.

Why...?
-You need help to remove the virus from computer ?
Or you want to be part of the anti virus company?

Good luck

Mai
