Once you have downloaded the file, simply double click it and it will install it's self and remove any older versions if you have any.  It will also pick up your registration number and take you step by step through the setup.  You will be required to get a few updates to get the database up to date.  You may also be required to Reboot your computer at some stage during the updates.  
 

This version is a lot different to the old one so take your time to get familiar with it.  If you have trouble sending your emails, make sure that you don't have a tick in Hang up when finished.  Having that ticked may not give AVG. time to do the scanning of your outward emails.  If you find that your computer is running slower after you install AVG there are other free antivirus programs available.  Avast Home being one of them.

AVAST HOME

Click the link below to read the reviews and decide for yourself. You can also download from there.  Please note that if you are on dial up that it is rather a large file.  If you ask it can be downloaded for you at SeniorNet. You will need a flash drive to put the download on though.
