Yes on #3 (for real time scanning for now)...

>For now, I have taken these actions, based on recommendations in this thread

>(1) I have excluded the folder where all my project files are located so that it is not scanned by antivirus
>(2) I have turned off write caching
>(3) I have set all the temp files used by VFP into their own folder (hmmm, should this folder be excluded from AV as well)
>(4) I have removed FoxUser.
