ransomeware

We run the Avast free antivirus.
today we got hit with ransomeware, we can use the laptop
but the main screen has the warnings on it.
Avast will get rid of it for $179.00 for a year.
Does anyone know how to get rid of it>
Thanks

And where did you see this? If you called avast phone support, it is outsourced to a third party :-\
