Its the truth Atnes. Anyway, as I said *previously* which you have for some reason decided to ignore, thers a bunch of operating systems you could use for free that are secure such as Linux and BSD. Some of these are:
Ubuntu
Opensuse
CentOS
FreeBSD
OpenBSD
etcetc
Its Microsofts doing, not mine, and their solution to XP for their commercial, licensed closed source products was Vista. XP security is wrong and its not possible to fix it by installing third party apps. This is why the number of vulenarabilities in XP is far higher than Vista, even though Vista has millions more lines of code in it than XP.
