Not on the download it won’t, as I asked specifically would the avast 5 download be much bigger than the 30MB it is already and I was told it wouldn’t be. The difference in avast 5 is the signatures will be unpacked on installation (taking much more HDD space, which wasn’t concerned with) so they don’t have to constantly be unpacked.
