Norton Antivirus for Mac v 11.0.3

Asked By 0 points N/A Posted on -

Hi all I read as well as follow the lessons from mikeromo but still I get an error message — a microdefs error.

Then I reboot, start Live Update, and also download the virus defs. Everything looks like to be installed. Even I uninstalled and reinstalled again. The error message is:

Microdefs error

LiveUpdate had an error updating the virus definitions.

OK

 

I am having troubles importing a second graphic to this message (I find an 'An Unexpected Error has occurred. An Unexpected Error has occurred'- error message). As a result I need to type it: LiveUpdate for Mac v 5.1.1; Vulnerability Protection Engine for Mac v1.3.0; Vulnerability Protection for Mac Latest; Symantec Scheduled for Mac v5.0.3. Norton Antivirus for Mac v 11.0.3; All has a green test by it without NAV for Macintosh Virus Defs.

Because it has a red ring on it with white hyphen as well as the version says new. However when I try to rerun LiveUpdate, then it states there is a later edition. I need to solve this. I need a solution.

Please help me.

Thanks a lot.

Hello Tammy,

You are getting that error because LiveUpdate may be having difficulty downloading multiple updates at once.

You can be able to run LiveUpdate so that it can update an individual item at a time, and this will make it possible to complete each update without getting an error message.

The following are the steps you should follow:

  1. First you will need to run LiveUpdate.
  2. And then you will click the Customize This Update Session.
  3. After that you will need to uncheck all but one item to update, and then click Update.
  4. After the update is complete, you will click OK.
  5. And then repeat steps 2 to 4 till each item has been updated.
  6. And then reboot your computer.

Regards,

Carl

Dear User,

This could happen because of few reasons such as,

The File permissions within the Antivirus Engine folders are incorrect.

Or update isn’t compatible with Mac OS X

The solution is

Try applying the Intelligent Updater

However if it doesn’t work,

Go to terminal and type

cd /Library/Application Support/Symantec/AntiVirus/Engine

Look for these files and verify the permissions are correct as shown below

-rw-r–r–   1 root  admin    337744 Feb 23 17:33 navenmac.dlb
-rw-r–r–   1 root  admin   3379384 Feb 23 17:33 navexmac.dlb

If they read -r–r–r—then they are incorrect . use this command to correct them chmod 644 *.dlb

Thank you

Because the error happened when updating Norton Antivirus’ virus signature database, make sure your internet connection is working. Open your web browser and visit a website then try clicking some links. If your connection seems to be working when opening links, try visiting YouTube and play one video to see how fast your connection is when buffering videos.

If the video takes time to buffer, it means you have a slow connection. When you have a slow internet connection, the downloading of the virus definitions in Norton antivirus is affected. Sometimes if the connection is too sluggish to handle downloads, the downloading of the virus definitions gets interrupted and stops at a point. Try resetting your router.

Turn off your router and unplug it from the power for about 10 to 20 seconds. Press on any button to drain any power left. Next, plug it back to the power and turn on the router. When the connection is ready, try updating your Norton antivirus again and see if it works. Also, try updating to the new Norton Security Deluxe.
