Avast/Setup folder

Does anyone know if it’s safe to delete the files in the Avast/Setup folder.
I’m not sure if they’re files the program uses or whether they were just used to install/update it.
Thanks,
Dash

It’s not a good idea to delete them.
avast! uses them to update itself - if you delete it, it would always download the whole package instead of the increments. Actually, I think some important files are stored there as well - so the updates wouldn’t probably work at all.

Thanks for the info!
