I have tried unsuccessfully several times to register/obtain a license key for your fine product (avast 4 home edition/personal use). I’ve filled out the form on your website multiple times but never get a response. I have the avast.com domain authorized as a sender in my email filter, as well as support@avast.com and register@avast.com on my allowed senders list yet your bot never seems to send anything. Please let me know what to do (can I register privately via these forums maybe?)
I am sorry that you are having a problem with registering. Have you tried sending an email to … support @ avast.com (no spaces needed)?
Also, David asked about spam filtering by your ISP. I would also ask if you use your own spam filtering program? If so, you might need to exclude avast.com from being filtered … depending on how aggressive the spam filtering is.
