Hi girdsanak, welcome to the forum 
First an answer to your question :
Support Ticket Refund https://support.avast.com/support/tickets/new?form=2
Sales: Orders and Renewals FAQ https://www.avast.com/faq.php?article=AVKB24#artTitle
But may I ask which anti-virus did you use before Avast ? And have you removed it properly ?

@girdsanak: Post your ticket ID in your next reply and I will report it to the admin and one of the avast team member will assist you.
He’ll receive assistance from Avast once he files the support ticket.
The posting of the Support Ticket is only needed if there’s a problem with the reply from Avast.
Why not first try to solve the problem ?
Is any (pre)installed other av removed completely ?
Is there any other security related software installed ? (or was there).
Does it happen in all browsers/with all websites ?
What OS/SP ?
What are the system specs ?
