Google Pack (background info) is this clever package of software that's great for fresh / new PCs, it gives you 6 months of free anti-virus software, acrobat reader, ad-aware (anti-spyware), google toolbar etc all in one install package, so you only need to click "I accept" once, and don't have to download / install all the programs seperately. Would be nice if it included shockwave/flash player as well though.
