Well, on my machine it updates at least 2 times a week,...miminum,...
I do not check it that much,...cause when I am at work I use MacOS X Panther,...so no compatible Avast soft for this OS.
I might agree with you Mantra if you say that other AV's add new virusses every day,...
NOD32 seems to update very fast daily,..
Maybe indeed there should be more frequent updates,...daily,....if possible!
However I do not know how the updates are scheduled at Alwil.
As for me Avast! caught all the virusses I received by email and I haven't got any single virus yet!
I admit,...I have scanned my PC with trials of other AV's to test if Avast is doing its job!
(no offence Alwil,..but this is just to find any leaks) and things seem virus-free,...so,...
If you have the pro,..you have the so called "push updates" (if I remember correctly),...faster updates,....
However one tiny question towards the programmers perhaps:
-> What is meant by: "Standard update"? Are it just trojans and little viruses who are not that dangerous?
Cause when newer virusses like Zafi-D are added, it is mentioned in the emails I receive from Alwil.
