概要

In some circumstances, it might be necessary to update the Endpoint Protection for Mac/VirusScan for Mac .DAT files manually. For example, to respond quickly to an outbreak situation.

In addition, a manual update may be required in scenarios where Endpoint Protection for Mac/VirusScan for Mac cannot perform automatic updates.
To manually update the DAT files, follow the steps below.

解決策

You must perform the steps below with the user logged in as root or issuing commands via sudo.

NOTES: 
  • As Mac OS is UNIX-based, commands in the Terminal are case-sensitive. Ensure that you type the paths and filenames in the correct case, otherwise, you may experience file does not exist errors.  
  • Depending on your permissions, you may need to log in as or switch user to the root user to complete these steps.

  1. Launch your web browser and go to the following location:

    ftp://ftp.mcafee.com/commonupdater

     
  2. Download avvdat-xxxx.zip, where xxxx is the DAT version, for example 6112.
  3. Unzip avvdat-xxxx.zip and store the files in a temporary location, for example to a folder on your Desktop called Temp.
  4. In the Finder, click Applications, Utilities, Terminal to open a terminal session.
  5. Change to the /usr/local/McAfee/AntiMalware/dats folder by typing the following and pressing ENTER.

    cd /usr/local/McAfee/AntiMalware/dats/
     
  6. Type the following command and press ENTER:

    mkdir xxxx

    Where xxxx in the command above refers to the DAT version being applied.
     
  7. Use the cp command to copy the avvclean.DAT, avvscan.DAT, and avvnames.DAT files from the temporary folder to the xxxx folder. For example, if these files are in a folder called Temp on your desktop, type the following and press ENTER:

    cp /users/<username>/Desktop/Temp/*.DAT  /usr/local/McAfee/AntiMalware/dats/xxxx  

    NOTE: If logged on as root, you can also type:

    cp /private/var/root/Desktop/Temp/*.DAT /usr/local/McAfee/AntiMalware/dats/xxxx

     
  8. Change the file and folder permissions by typing the following commands. Press ENTER at the end of each line.

    cd xxxx
    chmod 644 *.DAT
    cd..
    chmod 755 xxxx


    Where xxxx in the command above refers to the DAT version being applied.

     
  9. Type the following command and press ENTER to convert the plist file from binary1 format  to xml1 format:

    sudo plutil -convert xml1 /Library/Preferences/com.Mcafee.ssm.antimalware.plist

     
  10. Open the com.Mcafee.ssm.antimalware.plist file for editing by typing the following command and pressing ENTER:

    vim /Library/Preferences/com.Mcafee.ssm.antimalware.plist 

     
  11. Locate the string  <key>Update_DATVersion</key> and its corresponding value <string>xxxx</string>.
  12. Press i to enter Insert mode and change the value of xxxx to the version of DAT being applied.
  13. Press ESC to exit from Insert mode.
  14. Press :wq to save changes to the plist file and exit the Vim editor.
  15. Type the following command and press ENTER to convert the plist file back to binary1 format from xml1:

    sudo plutil -convert binary1 /Library/Preferences/com.Mcafee.ssm.antimalware.plist

     
  16. Close VirusScan (if it is running) and type the commands below to reload the product and press ENTER at the end of each line.

    sudo launchctl unload /Library/LaunchDaemons/com.mcafee.ssm.ScanManager.plist
