The Norton extension for Safari cannot communicate with the Norton Security application.

Just installed Norton Security 7 on my Mac OS X 10.11.x computer and am getting the error "The Norton extension for XXXXXX cannot communicate with the Norton Security application."  It's happening in Firefox v.42 and in Safari 9.0.1. The XXXXXX in the message reflects whichever browser I'm running. Google Chrome Version 46.0.2490.80 (64-bit) doesn't give me the error but shows a ? in a square for the Norton icon on the navigation bar and doesn't appear to be working either.

Is this a known issue?

Thanks

Actually Chrome gave me the same error, it just took it about 5 minutes to come up. Every time I open a browser with the Norton extension enabled I get a new tab with the error. The only way to stop this action is to disable the extension, but then I don't have the advantage of safe browsing.

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

Hey KCMac, 

I apologize for the inconvenience. It seems like the extension is not communication with our background process. 

You can try the following steps please

  1. Download the tool from here:ftp://ftp.symantec.com/misc/tools/mactools/GatherSymantecInfo.zip
  2. After download, with the file on the Mac client where you are facing these issues, double-click on the file to expand it. It will contain the GatherSymantecInfo.command file as well as a folder called SupportFiles.
  3. Double-click on GatherSymantecInfo.command. It will open a Terminal window.
  4. Enter your administrator password (it will not echo on-screen) and press Enter.
  5. Gathering information... message will appear.
  6. When it completes to run, you can find SymantecInfo.zip archive under Desktop directory.

Can you send me that zip file via a private message ? I will contact you privately as well. 

Can you also try restarting you Mac to see if that will relaunch the process ? 

Thanks,
Harsha

SymDaemon cut the battery life of my Retina MBP down to 2 hours. I decided the best thing to do was to uninstall NS 7. that fixed my battery issue.  Maybe I'll re-install after the product comes out of beta.

I am having the same problem. I've created the zip file but there is no way to attach it to the email in private mail. Do you have any other suggestions?

Hi Harsha,

I have the same problem. How can I upload the zip file in a private message?

I'm having that problem too. 

Is there a way to resolve this issue?

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

For those of you asking about the battery draining, please look at the thread here:

https://community.norton.com/en/forums/symdaemon-frying-my-cpu

If you could post on that thread a sample of SymDaemon that would be useful. To do so, open Launchpad, and find the "Terminal" application in Utilities (or search for it). Then when the Terminal window opens, copy and paste the following into the Terminal window:

sudo sample SymDaemon -f ~/Desktop/SymDaemon.txt

(You'll have to enter your password).

This will write a file on the Desktop. Please post it on that forum, or send a private message to me with that information.

Same issue here with this "Norton extension for Safari cannot communicate with the Norton application"

Has there been a resolution?

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

If you have the "Norton extension for Safari cannot communicate with the Norton application" issue, please make sure that the Norton browser framework process is not restricted from accessing the Internet. If you have Little Snitch installed, you must grant our processes access to use the Internet. This cleared up the problem for one customer.

If you don't have Little Snitch installed, please make sure the "NFMWps" process is running. You can verify by launching Activity Monitor, clicking on the "View" menu, and selecting "All processes". Then filter/search for the process "NFMWps" (that's Norton for Mac Web Protection Service process) is running. 

If you don't see it, then it somehow was quit. Try restarting your Mac.

You can also run Gather Symantec Info to get us this information. Download it from here: ftp://ftp.symantec.com/misc/tools/mactools/GatherSymantecInfo.zip 

  1. After download, with the file on the Mac client where you are facing these issues, double-click on the file to expand it. It will contain the GatherSymantecInfo.command file as well as a folder called SupportFiles.
  2. Double-click on GatherSymantecInfo.command. It will open a Terminal window.
  3. Enter your administrator password (it will not echo on-screen) and press Enter.

When it completes, you can find SymantecInfo.zip archive on your Desktop.

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

Hi Ryan, awesome quick answer! Will try that, don't think I have Little Snitch installed, but will 2x check.

Do you by chance know a thread where I can find a solution to this? 

When I fire up Skype, NS pops up with; "An unknown service (port xxxxx) is starting on your Mac" Then four options;

Allow all connections

Allow local connections

Deny all

Don't change firewall

Tried many times e.g. here; https://community.norton.com/en/forums/unknown-service-port-46101-starti...

Can't  find the answer to which one to choose?

Thanks in advance

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

I've replied on the other thread.

To help diagnose the Chrome problems, please send me the GatherSymantecInfo report. It sounds like you don't have Little Snitch installed.

However if you're experiencing problems with the firewall, it could also be Connection Blocking. Try turning off Connection Blocking to see if it solves your porblems with Chrome.

If it does, let me know and I'll let you know how to work around it. If it doesn't I'll need the Gather Symantec Info report to get more information.

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

I had the same problem. It started after installation of NS7 as an upgrade from NS 6.4 version.
 Searching the web, I landed on a page that suggested to download RemoveSymantecMacFiles.zip (found here: https://support.norton.com/sp/en/us/home/current/solutions/kb20080427024142EN_EndUserProfile_en_us).

I ran command as described in kb solution to completely clean my Mac (El Capitan 10.11.2); after a reboot, I installed NS7 again without any problem related with browser plugin.

Good luck

How do I restart "NFMWps" process when "restarting your Mac" doesn't restart "NFMWps"?

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

As a followup (to my post immediately above) - I've just seen the following lines in the Mac Sys Info log...

23 Jan 2016 5:19:38 pm com.apple.xpc.launchd[1]: Could not find and/or execute program specified by service: 2: No such file or directory: 
/Library/Application Support/Symantec/Silo/NFM/WebProtection/NFMWps

However the NFMWps does exist (in this folder) and ran in a Terminal window after double-clicking it - but only while that Terminal window is open. Why would it be refusing to load upon restart? Is there a way to fix this without reinstalling Norton?

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

I have the same issue, just downloaded and updated to the new Norton Security 2.0. It loaded into Chrome, but not Safari or Firefox.

Thanks for any help! This seems to be a recurring problem for many people.

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

I am not getting the error but the Norton button in safari and chrome always have a "?" in it.  When I click on the button it just states that the page is untested.  I get this no matter what page I go to and no matter which browser I use.

Re: The Norton extension for Safari cannot communicate with the Norton Security application.

I am having the same problem as well with Safari. I downloaded the Gather Symantec Info and have the zip file saved. Where should I send this file?
