downloaded avast virus protection on Mac side how do I get it to Parrallells Windows side?

[jdc]

if you arent ever going to put the windows side online, then i would say dont bother with anti virus

as for windows updates, same logic

if the XP side is working perfect for everything you need, then dont upgrade XP

there will probably be fewer and fewer updates for XP as time goes by, its all a new vista now...
