No problem, welcome to the avast family and the forums.
Stick around and browse the forums, especially the sticky topics at the top of each of the forums, not to mention the avast help file. They provide a wealth of information to help you get the best from avast.
Note there has just been a program update released, we have been running beta tests for a couple of weeks, just right click the avast 'a' icon, select Updating, Program Update. The normal automatic program updates are cycled over a 7 day period to ease server load, so one of the benefits of being a forum regular if getting early notice of program updates.
