Avast charges

How to know what is Avast charging in my bank account?

There really is insufficient information to give you a definitive answer.
What Avast Product/s do you have ?

Surely you would have received an email from avast when you purchased your product/s ?

If this is for an upcoming renewal, you should receive an email before that renewal takes place and should notify you of what the charge is. This happens about a week to ten days before I believe.

Unless you particularly enjoy receiving SPAM, I suggest that you remove your email from a publicly available forum.

Did you happen to use the 60 day trial option ?
As that would have setup a payment mandate, otherwise how would they have got your bank details.
