I was going to buy the professional edition of Avast, but thought i would try out the trial version first.
But it only gave me 4 days before the licence expired.
Disappointed about the trial.
Why? Trial version can be used for 60 days but you can't receive a greater period after you install it once in the computer.
This is an antipiracy feature.
Anyway, I'm sure if you ask for an extended period, you can ask on sales@avast.com
If you install the Home version and do not Register, the trial period start to be 'used'.
Anyway, check your system date and time
