Inquiry on Credit Card Charge

I was charged under my citibank credit card the following: DRI *AVAST Soft Shannon, Co. IE amount $29.95. I do not know what is this all about. Please help. I have forgotten about this.

Now I know that the $29.95 was intended for automatic renewal but the problem is the computer where it was installed is no longer functioning because of hardware problem. Can I transfer the purchase I’ve made in other computer?

Unplugging a computer or throwing it out does not cancel autorenewal.

Yes, you can transfer your license to a new computer.

Please submit a ticket for further assistance as I will need to look up personal information to properly guide you.
