I have 2 pc sharing internet connection through a modem-routeur.
May I use my same Avast home edition on both?
Are both of them HOME and NON-COMMERCIAL usage?
If so, no trouble... sharing the same Internet connection is not the problem here...
if yes how can I install it on the second pc?
As you've done on the first one...
I mean, run the setup file, use the same registration key... be happy
