How to download avast free software?

I need to purchase the avast software before that I want to download it

Try looking at the top of the board to which you just posted http://forum.avast.com/index.php?topic=139606.0

  2. the whole point of free software is that it is free. You can download the avast free version and it costs you nothing.

If you want any of the other products, avast Pro, avast Internet Security or avast Premier, then you would eventually have to pay for those. You can however, download one of the paid products and use it on a trial basis for up to 30 days. At that point you would have to pay or uninstall it and install the avast free version.
