I've tried everything, reinstalling the software, turning off Time Machine, leaving the computer alone overnight, turning off the screen-saver. I've contacted Norton Support 5 times, they taken control of my screen three times and it still does not work. My wife runs OSX 10.7 Lion and it runs the idle scan with out incident. No one seems to know what the problem is. Can anyone shed some light on this. One last note, the idle scan select is on as is the entire program. I am running Norton AntiVirus for Mac 5 Version 12.3 (71)
I am seeing the same problem, idle scan ran once, the first day I installed Norton. It has not run since. Closing all apps, then rebooting does not help. I am running this on a new MacBook Air.
I also have Norton AV installed in a Win 7 instance running under Parrallels. When the virtual machine is running, the Win 7 Norton AV idle scans run.
Hi Bobofee,
Sorry about this, it looks like we are not able to reproduce the problem. Can you please provide the model of your Mac computer? It helps us to isolate the problem much better.
I, too, cannot get Idle-Scan to run after the initial normal run.
I have a mid-2011 27" iMac with a 3.4 GHz Intel Core i7 processor. My operating system is Mac OS X 10.8.2 and I am using Norton Anti-Virus for Mac 12.3.
I'm running a new 13" Mid 2012 MacBook Air 2 GHz Core i7, 8 Gig Ram, OSX 10.8.2, Norton AV 12.3 (71)
Idle time scanning takes into account a lot of factors, including system load averages. But there are other factors at work here, and the simple act of running a command to gather more information for us will unfortuantely interfere with all those other factors (a Heisen bug, so to speak).
Having said that, open the Terminal application on your Mac, and let it sit for a while. When your machine is completely idle, and you think it should have started run the command "uptime" in the Terminal window. This will tell you the load averages.
The load averages should be between .50 and .25 before idle time scanning will think about turning on (there are other things it takes into account as well, such as whether you are using the machine at the time).
YOU HAVE ALL OF THIS INFORMATION SEE CASE NUMBER 05502050. MAC PRO IS THE MODEL
I have on rare occations gotten idle time scans to run. I'm running 10.8.2 on a 2012 MacBook Air with a 2GHz i7 processor and 8 gig of RAM. What I typically see is an idle time scan will start after a clean reboot with no applications running. Most times when I look in the logs the idle time scan cancels. User intervention is not what's causing the scans to cancel. I've tried this over night with the same results. I have the power settings set not to put the machine to sleep when plugged in to eliminate that possibility. I have noticed that the scan is more likely to complete if I'm connected vie eathernet vs wifi, but I have seen scans canceled when on eithernet as well.
Once the idle scan cancels it will not run again until I do a manual full system scan and then reboot. I have not exhaustively tested all the scenarios so there may be other ways to get them to come back.
I have a Parralles virtual machine with Windows 7 that I use on the same machine. During the day I typically have multiple MAC and Windows applications up and running, usually Outlook, Word, and Powerpoint on the Windows side and Safari, OSX email, and OSX calendar running on the MAC side. If I walk away from the machine for a while I will see multple Norton idle scans completed in the Windows virtual machine. Parralles is set up to favor speed in the MAC OS, not Windows. This leads me to believe there is more to this than load averages getting in the way.
