An Extra.DAT is a temporary detection file created by McAfee Labs. It is used to detect and remove threats that have not yet been added to the regular DAT files. You must apply an Extra.DAT to the infected system and any systems that could potentially be compromised.
With a standalone VSE installation that does not use a central update repository such as ePO, you must apply the Extra.DAT locally.
To apply an Extra.DAT locally:
- Copy the Extra.DAT file to the following folder:
/usr/local/McAfee/AntiMalware/dats/Current DAT folder/
- Rename Extra.DAT to AvvExtra.DAT.
- Make sure that the AvvExtra.dat file has the same file permissions as AvvScan.dat. This value should be 644.
- Make sure that the AvvExtra.dat file has the same owner permissions as AvvScan.dat. This value should be root and Virex.
- Restart the Mac and validate the Extra.DAT displays in the About box and McAfee security logs.
