Norton alerted me to OSX.Trojan.Gen in 10.11.1 update.

Updating my Mac Pro 13" last night with 10.11.1 and iTunes and Norton alerted me to OSX.Trojan.Gen which it had found in the update and deleted.


Is Apple aware of this problem and what are they doing about it?

MacBook Pro, OS X Yosemite (10.10)

Antivirus apps not infrequently misidentify mac files.

Do not be concerned.

Trojan Gen 2 virus

Also this

OSX.Trojan.Gen is a generic detection for many individual but varied OS X Trojans for which specific definitions have not been created.

Not the work "generic'. That does not mean an it is bad/Trojan/virus

Get rid of Norton.


Norton Antivirus (made by Symantec) has a very long and illustrious reputation for mangling Mac OS X systems, sometimes to the point where a complete reinstall is necessary. Among other things, it installs kernel extensions which are known to cause kernel panics and system freezes; it contains known and documented bugs which can silently corrupt Adobe Photoshop and Adobe InDesign files, destroy a user's ability to authenticate as an administrator, and (on PPC systems) can cause Classic to stop functioning; and Symantec has on at least two occasions now released flawed .dat file updates which erroneously report certain critical Mac OS X files as "viruses." (Deleting these "viruses" causes damage to the system that in some cases renders it unbootable.)


Norton has also been reported as damaging iPhone backups.


A major security flaw in Norton has also been noted:
