I want to download the Comodo firewall, yet there seem to be two possibilities for Windows XP Home--there's a version for 32 bit systems and another for 64 bit systems. How do I know which one to download?
well you should know if you have 64 bit as 32 is the standard type but you can check by right clicking on my computer and clicking properties, if it says "Windows XP Home/Pro Service Pack 2" then you have 32 bit
