The latest answer said to "simply install Avast on the other computer, and use my license file. I have my license file, but my problem is how to install Avast on my husband's computer in the first place. I have an Internet Security good till 2013, and he has one that is running out right now. If I just go onto his computer how do I prevent Avast from renewing that one or charging me for a new program? I don't want to have 2 separate Avast programs going.
