Hey,
Im thinking of buying avast, but I have a question.
I often change my computer, install new OS’s, reformat, etc. and was wondering if I would have to buy a new version of AVAST PROFESSIONAL each time i reinstall windows?
Thank you in advance,

You are supplied with a registration key when you purchase Avast! this can be loaded as many times as nesessary within the period of your licence.
welcome to Avast forums 
Thank you Thats good to know. Now one more question, I currently have Vista RC1 Installed, would it work with that? Eh I guess the best way to find out is to try it 
Or you could use the forum’s search function, type in “Vista RC1” for useful information before you try it.
