Could it be related to my recent download of McAfee from AT&T?

Perhaps, but McAfee is worthless junk that is capable of doing nothing beneficial. Uninstall it and ensure all remnants of it are completely eradicated from your Mac, then determine if that made any difference.

 

If not please determine if the problems also occur in "Safe Mode":

 

  • Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
  • You must disable FileVault before you can start your Mac in Safe Mode.
  • Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
  • Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
  • To end Safe Mode restart your Mac normally. Shutdown will take longer as well.

What computer are you using? Some Mid-2010 MacBook Pros (I think that's the one) have some known graphics processor issues that Mavericks seems to bring to light.

    You have the MacBookPro6,2, the Edsel of Macs. It has a defective logic board that may be covered by this recall program:

    MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.

    Print the first page of the panic report, and the support page linked above, and bring them with you.

    Note that the recall only applies within three years of purchase. After that, Apple may refuse the service. In that case, you may be quoted a price of about $300 (in the U.S.) for a "depot repair," which involves shipping the unit to a central repair facility and takes about two weeks. For that flat fee, anything found wrong with it should be fixed, not just the logic board.

    The model was discontinued in February 2011, so the replacement program will be ending quite soon.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

     

     

    Sometimes the replacement part is also defective, so be prepared for that possibility.
       
    If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
