Weirdness with Automatic Live Update after resuming from Hibernation or Standby

I have a question about Live Update running after a machine has been in Standby or Hibernation for a long period.

In older versions of LU, if the time the computer was resumed after the time that Live Update was scheduled to run, LU would immediately run as soon as the computer was resumed from standby or hibernation.  This caused performance problems when resuming from standby or hibernation and thankfully was changed in the version of LU that came with NIS 2008.

Now on resuming from standby or hibernation, LU reschedules itself to run in 15 minutes.  This is good, but I've noticed something weird about this.  Live Update runs every hour (regardless of the settings) to check for updates for the anti-phishing component.  By default it checks for virus updates every 4 hours.  So one would think that if the machine is hibernated for more than 4 hours, that the next time Live Update automatically runs after resuming it would check for new virus definitions.  It does not.  What appears to happen is that it continues counting from the time the machine was suspended.  So Live Update doesn't seem to check for new Virus Defs based on the time since the last check, but on the number of times Live Update has run since the last check.

For example, say that Live Update downloaded new virus definitions at 3:00 PM on Sunday and then the user hibernates the machine at 4:30 PM on Sunday.  The user then resumes the machine on Tuesday at 10:00 AM.  Instead of Live Update checking for new virus definitions at 10:15 AM (when it first runs), it doesn't do so until 12:15 PM (3 hours later).   In this example, 12:15 PM was the 4th time it ran since Sunday 3:00 PM, even though it was over 45 hours later.

Is this what's supposed to happen?  

The reason I ask is that I always put my laptop in hibernation.  If I only use it for an hour a day, it takes 3 or 4 days to automatically update the virus definitions, which is a long time.

Re: Weirdness with Automatic Live Update after resuming from Hibernation or Standby

Hi Morac,

Our apologies for the late reply to your inquiry. We were able to reproduce the scenario that you described with LiveUpdate 3.4. Since this is a somewhat unusual use case, we will not be creating a fix for LiveUpdate 3.4 at this time. I have requested that we document this scenario in the knowledge base so that we can receive feedback from other users who experience this issue.

I have confirmed that this problem will not occur in the 2009 product, which will update virus definitions more frequently. When the 2009 product comes out, you will be able to download and install it for free, provided you have a current subscription to the product.

Thank you for bringing this to our attention.

Re: Weirdness with Automatic Live Update after resuming from Hibernation or Standby

Thanks for looking into it.  It's not terrible since it will update the virus definitions if I run LiveUpdate manually after hibernation.  I just thought it didn't seem right the way the automatic updates were working.  Most people probably would never notice it.  In fact it took me a while to figure it out myself.

If you do fix this for 2009, please leave the 15 minute wait time after resuming from hibernation or standby.  I really like this since it prevents the disk thrashing that used to occur in previous versions which ran immediately.
