Q: System crashes with El Capitan

Since I installed El Capitan (a couple of months ago) I've had regular system crashes. I'm lucky to get 2 hours of uninterrupted use. It doesn't seem to matter what apps are running, it even happens when the machine is idle. I've run EtreCheck, and subsequently Malwarebytes AntiMalware, but this had no effect. I've updated to 10.11.1 and yesterday to 10.11.2, but again to no effect. Strangely, almost all of the crash logs mention "com.Symantec.kext.intenetSecurity", but I uninstalled Symantec when the license expired, and even ran "RemoveSymantecMacFiles" app, so I don't understand why there are any Symantec fragments remaining. I'm running a 2.7GHz iMac with 8Gig of memory. Any help would be appreciated.

iMac (21.5-inch, Late 2012), OS X El Capitan (10.11)

    Please hold down the option key and select System Information... from the Apple menu. The System Information window will open. Select

              Software ▹ Extensions

    from the menu on the left. After a delay of a minute or so, a list of all installed kernel extensions should appear in the upper right pane of the window.

    In the extension list, click the heading of the column Obtained from twice to sort it by source, with Apple at the bottom. At or near the top, you may see the third-party extensions. Select one, and information about it, including Location, will appear in the lower right pane of the window. What do you see?

    1. Those for "Identified Developer" are located in /Library/Extensions, while the unsigned are in /System/Library/Extensions.

    2 . I ran RemoveSymantecMacFiles a couple more times , and it is now NOT telling me that there are kexts files. So, maybe some success?

    If you don't see anything from Symantec in System Information, then it's most likely gone.

    A status report. After running RemoveSymantecMacFiles 3 times the kexts were eventually removed. I've now had more than 24 hours of use without a crash, so all seems fine. Thanks each of you for the help.
