I uninstalled SAV 10, and ran the SAV 9 version of no nav to get rid of any other odd remnants. I’d already run the windows installer cleanup utility. After a reboot and a new install, SAV 10 is working fine now. I’m running a “quick” scan. Its using 87 MB of ram. :0 Hopefully that does down once the scan is done. I have found on other systems SAV 10 seems to gobble up 30-35 MB.
