SymDaemon activity following NAV v7 upgrade

Since upgrading my iMac (i7 cpu) to the latest version of NAV (v7 or is it v12???) I noticed cyclic fan activity when doing nothing on the Mac. Further investigation showed that the fan activity was coupled with SymDaemon activity which was hammering the cpu at 390%, this appears to be across 4 of the 8 cores.  I'm assuming this is related to the idle scan, but I don't have the knowledge to prove this.

Interestingly I've not yet seen the same behaviour on my MBP i7 or MBP core 2 duo, but there's still time I suppose!

All are running El Capitan 10.11.3.

Anyone else seeing similar issues?

Re: SymDaemon activity following NAV v7 upgrade

Same problem.  I've researched this extensively, and the only solution is to remove your Norton products.  Be sure to cancel any automatic billing, then follow the bottom set of instructions on this link:

https://support.norton.com/sp/en/us/norton-security-mac/current/solution...

I've tried all Norton support options, but they don't even admit there is a problem.  Too bad, I used to like there products.

Re: SymDaemon activity following NAV v7 upgrade

Yesterday I made the error of upgrading to Version 7.0.1 for my Macbook Pro. As soon as installation was complete, CPU SymDaemon began running my CPU at over 100% with my fan running very high.  I contacted Norton Customer Service and they remotely reinstalled the software on the computer.  The problems did not go away.  

The next day, I contacted Norton Customer Service again and requested to be downgraded back to Version 5.9, which has worked well for me up until I upgraded.  They said it was not available.  I explained the problems withe CPU and fan.  They said they had an "older" version they would install on my Mac. The "older" version they installed was the very same Version 7.0.1 with the same results.  Customer Service pretty much gave up, and finally said there was nothing more they could do.  No fix.  No offer to refund my two year renewal.  No offer to help me go back to Version 5.9.  Nada, after two hours of them controlling my computer they came up blank.

I had to completely uninstall Norton to have a quiet computer again.  Thanks to my foolish upgrade efforts yesterday, I now own a 2-year deluxe subscription for 5 devices, none of which are being used or will be used, plus I have zero protection on my Mac.  Kind of hard to believe.  I think Customer Service really tried to fix this, but there is obviously a problem with the product, and management has ruled out letting people use old versions.  Sad.

I did a clean install of my Windows 7 Pro SP1 because I was having over heating problems too. I put all my software back on again except my Norton Security suite and my over heating and fan problems have not happened since. I will no longer be using Norton products.

Re: SymDaemon activity following NAV v7 upgrade

I have been struggling with a similar problem for several months.  I can't find an answer. I called technical support and they took over control of my computer for a day and a half & uninstalled Norton and reinstalled it. Problem still occurs. Basically I run out of application memory and when I checked  Activity Monitor I see that SymDaemon Is consuming both memory and processor time. The only  way I can get the computer working again is to shut it down and restart it. This may work for a few hours or a couple days. It sure is a pain in the .....  After dealing with technical support for it they did admit the problem is known in the tech experts are working on it. The fix was supposed to be out the latter part of May or 1st part of June. Well it didn't happen & the problem is more active again than before. Turning off antivirus protection is not a solution. That's why I have been using Norton for the last 20 year or more years, for protection!

What is the solution or is there a solution? Can I continue to use Norton and you get the problem solved or do I look for another company?

Re: SymDaemon activity following NAV v7 upgrade

I have abandoned Norton after this upgrade. I have a laptop running solid state drives, an HP Zbook mobile workstation. After the Norton upgrade it was running hot and the fan was always running. Crazy. I completely removed all the Norton software (I used Revo Uninstaller Pro) and I am back to using Avast and Spybot. What was old is new and it still works like a charm.

Re: SymDaemon activity following NAV v7 upgrade

Thanks for the input. I'm about ready to move on to another company. I will are invested in time and money in Norton is sure would like them to fix the problem but I don't see any indication that they are interested in saving their customer base.

Watch this forum for a while to see if I get any response from Norton. Hopefully a solution.

Re: SymDaemon activity following NAV v7 upgrade

I gave up with Norton a couple of months ago, moved over to Bitdefender and what a difference!  Ok so it doesn't have a scheduler, but an Apple Script sorted that out.  But the low CPU hit is so refreshing after NAV 7, it also picked up a virus on one of my Macs previously protected by Norton.  18 + years of using a great product flushed down the drain by a lack lustre product and appalling support... Loose the grief bin Norton!
