AVAST is the Company from HELL!
I canceled my account and removed the software.
A year later they billed me and I had to spend 3 hours on the phone to get a refund and an assurance the account was canceled.
One year after that I got billed AGAIN and had to spend 2 hours on the phone to get a refund.
When I asked why they billed me again they said "Your canceled account is marked for rebilling"
DONT USE THIS COMPANY
