[amibroker] Re: Vista users and memory

Open the Defender control panel (I have this as an icon on my desktop)  -  the executable is in c:\program files\windows defender\msascui.exe

In the Options Setting - scroll down to the "Real-time protection options"  and uncheck the box that says "Use real-time protection".

This computer is dedicated to real time data acquisition and display  -  no email - minimal internet use etc.  So I run the batch mode virus checker once every week or two - no surprise - no viruses detected ;-).

This decreased memory usage AND improved the download/calculation speed since the CPUs weren't spending time checking for viruses in my real time data download.
