Have paid by MSM

Hello to all.

I have paid by phone text to install Avast and reading twice, it says that I can get the money back if not satisfied. but how?

That this means that the Avast will run correctly?

Thanks

Where (which site) did you buy it?
Maybe you can contact sales (at) avast (dot) com.

I am afraid avast! cannot be purchased by a SMS.
If you did, you are probably a victim of a fraudulent saleā€¦ please see here:
