Navlibx

While using their Macs as normal, some users have reported being interrupted suddenly by a seriously-sounding security alert. The message displayed by their device states that a file named 'Navlibx' could cause serious damage and should be moved to the Trash. Naturally, many come to the conclusion that this particular file is associated with threatening malware that has infiltrated their Macs or belongs to an intrusive PUP (Potentially Unwanted Program) that may be equipped with adware, browser hijacker and even data-tracking routines. After all, these are the typical triggers for that particular security alert.

The message displayed in the alert could be a variation of:

'Navlibx' will damage your computer.
This file was downloaded on an unknown date.
Report malware to Apple to protect other users.'

However, in this case, the file was flagged as potentially harmful, due to a software conflict or outdated security certificates. The 'Navlibx' file is a legitimate one that is a part of the security solutions provided by NortonLifeLock Inc., formerly known as Symantec Corporation. The possible mismatch likely occurred after a major update of the macOS, after which users started encountering the security alert. The problem should be resolved after applying all available updates to the system.

Keep in mind that many PUPs or malware threats could try to hide their files by assuming the identity of other legitimate and benign files belonging to real software products. If you notice any other suspicious symptoms alongside the alert about Navilbx, it may be for the best to run a thorough threat scan of the device. Use a reputable product to ensure that any unwanted intruders are promptly detected and removed from the system completely.
