I’m using Avast Free in Windows 7 Professional 64-bit system. Right now I’m using a promotional Avast Internet Security in test mode 20 days. I subtract 15 days trial. Now use the version 1.11.2241. Avast now has a new version 1.11.2245. If I upgrade version, will they respect me 15 day trial left me Avast Internet Security or Avast Free return me?. :-\
