All Done With Scheduled Scans

NAV 2011 does not appreciate it when you decide to schedule your own system scan. NAV would rather scan your system on its own schedule. Here are some of the stumbling blocks NAV threw in my way when I discontinued the Idle Time Scan and tried to create a Custom Scan of my system to run every Monday morning at 4:00 am:

1- NAV would not 'wake' my computer from standby (S3), even when I enabled 'wake the computer' in Windows Task Scheduler. I had to create a separate task just to wake the computer.

2- NAV would disable the schedule after the scan ran once. In other words, the scan would run once as scheduled, then never again. When I opened NAV I saw that my Custom Scan no longer had a schedule, and Task Scheduler reported that the schedule had been disabled. I eventually learned how to tweak the settings to 'trick' NAV into letting the schedule stand.

3- My scheduled scan took almost three-and-a-half hours to complete, whereas a manually-run scan of the same drives takes about 35 minutes.

4- The details of my Custom Scan aren't recorded in NAV's history, so it's very difficult to understand why the scheduled scan took so long. In fact, if you look at NAV's history alone you would never know my scan existed.

I see in the above a bit of the old "we know what's best for you" Symantec. Nevertheless, NAV's real-time scan is still among the best in the industry - according to multiple reviews - and the program does not slow my computer at all, so I'm sticking with it. However, I'm all done with its scheduled scans. And as long as I have to run a scan manually, I'll use Malwarebytes and get a second opinion as well.

Re: All Done With Scheduled Scans

Hi Bulldoggy,

I know you are talking about NAV, however there is a discussion here in regards to NIS and Task Scheduler and scheduling full system and custom scans.  It  touches on the scan being shown in Task scheduler and acutally running as scheduled, but Norton still showing that no schedule is set.  Norton is from all indication have duplicated this and is working on it.

There is an option on the General Tab of the scans Properties within Task Scheduler which permits you to run the scan with highest priorites - I am not sure if that will speed up you scan or not.

You willnotice there is a "Configure for" drop down in the task scheduler and we have found the OS choice has impact on certain options being grayed out in properties, so you might be able to work somwething our in that ara.

Please post back with results.

Re: All Done With Scheduled Scans

Hi Bulldoggy,

I saw your other recent thread on scheduled scans as well. Comments are as follows:

1. I'm not sure if this is NAV bug or Windows or perhaps a bit of both. Setting the schedule to wake the computer first should do just that.

2. I have never seen this reported where NAV would just arbitrarily do this. After you set up the schedule in NAV, what all did you modify in the Windows task scheduler? I recently saw a problem reported which I reproduced and reported to Symantec where the schedule gets installed as Windows XP. If you then change it to Windows 7 (or Windows Vista) via Windows task scheduler, NAV will no longer recognize that the schedule exists. Then if you attempt to go in and click on "Schedule" within NAV it will cause the Windows task to get deleted. Be sure also that it is properly configured as a recurring task.

3. You can try "run with highest privleges" in the General tab of Windows task scheduler. Edit: This won't help as it affects only the privlege level and not the task priority.

4. Are you still logged on when the scheduled scan comes due? If not there is a known bug which will prevent the scan results from getting logged in NAV history when it is run outside of user context. I have a workaround on this if this is affecting you.

MalwareBytes is a good on-demand scanner but be sure to get the free version only.

Best wishes.

Re: All Done With Scheduled Scans

Hi Bulldoggy,

Having to do with the length of time the scan is taking. As you no doubt know, when NAV runs and Idle full scan it does take longer because it is running at a lower priority as a background task. When you run the scan manually it will run as higher priority since you have chose to launch it yourself; e.g., it will run as a foreground task.

Scheduled scans are set as Normal priority. You can see this by right clicking the navw32.exe task from Windows task scheduler while the scheduled scan is running. Mouse over priority and you will see it set to normal.

When you run a manual full scan, navw32 does not appear to get launched but it may be that it is taking a higher priority when run this way.

I'll try to do some testing on this.

Best wishes.

Re: All Done With Scheduled Scans

I truely appreciate everyone's suggestions and ideas.    Please understand that I have been wrestling with this for several weeks now, and I really have no more patience for dealing with it. I decided to schedule a scan to avoid repeated prompts from NAV about its own scan. As you can see, this only lead to more frustration. It's just easier to initiate a manual scan, and as long as I'm doing so, I may as well get a second opinion from Malwarebytes. I continue to use and benefit from the real-time protection of NAV.

Re: All Done With Scheduled Scans

HI Bulldoggy,

I do understand but please do make sure and run full system scans periodically.

If you do decide to come back and look into this more, please let us know and we'll be happy to assist.

Best wishes.
