I'm stepping away from my old standby AV - more out of wanderlust than anything - and giving Avira a whirl. 30 day demos don't cost anything, so I figure I have nothing to lose. Is there anything special I should know about installing this with Vista64? Currently, it looks as if there is only one download available and it is compatible with both 32 and 64 bit. Are there any installation issues I should know about, or any tricks I will have to perform to get it working as it should? Thanks!
