Newbie here, love Vista which I just reacquainted myself with after installing new hard drive. Don't plan to upgrade to W7 after installing all the Vista updates. Much more stable, and a lot prettier than W7. My question is, when MS stops supporting Vista in three years, can I still use it if I have a great AV? I use Kaspersky Pure, have it running now. I have seen posts which say yes, just wondering what the experts here think (I'm definitely not an expert). Thank You.
