I’m using Avast 4.8 Pro and would like to find out how much space the virus definitions are using. Where are these stored in XP?

Update your avast! to version 6.
I (I guess as well as many others) don’t remember the 4.8 settings anymore.

I guess it was located in c:\Program Files\Alwil Software\avast4\Setup and there should be some files with the name containing the latest VPS number version

But, why don’t you update to the latest v6, like Asyn suggested

Thanks guys! You’re right, they’re in the Setup folder! Didn’t update because 4.8 is working fine and I still get updates for it so…???
