One last comment,.....why is it an 'issue' to send a program to another location of choice?
I have done this most of my computing life and have yet to see anything negative from it.
Is Avast somehow particular about this?
If so I would imagine that a custom install option should be eliminated.
I do the same thing on my XP machine BTW.
Just something that popped into my head from an earlier response.
Anyway,.....I will get back here sometime tomorrow and tell you how it goes.
