I have used it since the InoculateIT days as well, moved onto the paid
version and updated it every year since. I have had no trouble updating
the program to the current version.
I was slightly taken aback when they tripled the cost of the updates this
year but, after a bit of thought, decided to update anyway - it's a good
AV solution.
I now find that they are giving out a free copy to anyone who asks for
one. They obviously tripled the update price so that those of us who were
loyal to the application would cover some of the loss of sales caused by
the free version. Nice!
I hope it works for them but I, for one, won't be updating my ezAV (or
Pest Patrol) subscription next year.
