How to Fix Mcafee 5958 Error – A lot of McAfee users are having this trouble on an McAfee 5958 Error.
These steps are taken from McAfree Technical Support:
Workaround 1
McAfee has developed an EXTRA.DAT to suppress this detection. The file is attached to this article. This EXTRA.DAT does not fix the issue, it only suppresses the detection.
Apply the EXTRA.DAT to all potentially affected systems as soon as possible.
For systems that have already encountered this issue, start the computer in Safe Mode and apply the EXTRA.DAT. After applying the EXTRA.DAT, restore the affected files from Quarantine.
To apply the EXTRA.DAT locally:
IMPORTANT: For VirusScan Enterprise 8.5i and later, an Access Protection feature must be temporarily disabled before proceeding. For instructions on how to temporarily disable Access Protection in the VirusScan Console.
To apply the EXTRA.DAT locally:
1. Download the EXTRA.ZIP file attached to this article and extract the EXTRA.DAT file.
2. Click Start, Run, type services.msc and click OK.
3. Right-click the McAfee McShield service and select Stop.
4. Copy the EXTRA.DAT file to the following location:
\Program Files\Common Files\McAfee\Engine
5. In the Services window, right-click McAfee McShield and select Start.
For instructions on how to deploy the EXTRA.DAT through ePolicy Orchestrator (ePO), see:
