hi there
i have tried 3 avast license keys , and when i enter them then press OK, all say invalid. i have got the keys by registering on line. please help thank you
Hi,
Just wondering how you are entering the keys, as if you are copying and pasting, ensure you are not copying a space before or after the key. If you are typing the key make sure you are typing it correctly or try to copy and paste instead.

Check out this avast F.A.Q. link http://www.avast.com/eng/faq-registration-license.html#idt_220 or look at the video instruction Insert Registration Key - Video
Did you use the Trial version for a while?
Which version key (Home or Professional) are you trying to use?
Is your system time/date correct?
