Beware of free avast

Over time, they will withdraw money for this poor software from your account without notice.
They are extremely incorrect.

They cant do that unless you gave them your credit card info ?

I have been using Avast Free for over 16 years, I have never had money withdrawn by my account.

I have never used any of the trial versions of the paid products, so I have never given my payment authorisation and associated details.

Same here, In fact I never installed anything other than the web and file shields - to keep it simple,
and not buy into the security paranoia all A/V companies like to exaggerate.
