By updating weekly, you can protect your system more often from harboring many PC-based and UNIX-based viruses, and scripts and macros. You use the command-line to update your DAT files weekly.
NOTE: To update the DAT files using this method, you need to be able to log in as root (you do this by using the su command); OS X system security prevents many files and folders being visible to users. We recommend that only experienced command-line users attempt the weekly method.
To update your DAT files on a weekly basis:
Create a folder called dats on your computer or on a shared network drive that your computer can access.
Download the new DAT files from an approved site, for example: http://www.mcafeeb2b.com/naicommon/download/dats/mcafee_4x
.asp
The files are in a UNIX .TAR file or a Windows .ZIP format. Both these formats can be used on Macintosh OS X.
Select the UNIX platform. Put the file into the dats folder.
The downloaded file decompresses and creates a folder entitled "dat-xxxx Folder" where xxxx is an internal version number. The folder
contains several DAT files and other files.
In a Terminal window, enter the command su root. When prompted, enter the root password.
Change directory to the "dat-xxxx Folder" using the command:
cd "/dats/dat-xxxx Folder"
Enter the following command, which copies the new DAT files to replace the existing ones:
cp *.dat /usr/local/vscanx
Close the Terminal window.
You may now delete the dats folder that you created earlier.
Your DAT files have now been updated.
Updating Virex
To scan the disk later with these new DAT files when logged on as a user, you will need to run the following command from the Terminal
window:
Enter the command su root. When prompted, enter the root password.
