I'm not sure if this is the correct board to post this at but I was trying to buy the avast internet security edition from the avast online store which says it's for 3 pc's? and offers a disc version as well. My question is this: if I purchase this product and for any reason my hard drive were to fail or pretty much whatever were to happen once I paid for, and downloaded the product could I download it again to reinstall? Basically is it a one time download, 3 times only or as long as you have some certain information then you can always re-download it as needed in case you lose your current version? Thanks.
