Retrieving registration email

Avast Free Antivirus / Premium Security
1

How can I find out what email I have used to register my Avast Free? I just got a notice that my subscription is going to expire in 28 days, but it’s requiring me to input an email address in order to renew the registration. I have several email addresses, and I need to know which one I have used in the past. How can I do this?

Thanks.

If you are registering the Free version, it does not matter what email you used in the past. The easiest way to register is to do it online: http://www.avast.com/registration-free-antivirus.php.
