[Macpartners] mcafee security 1.2.0 (1549), won't update anti-malware

[arthur steinberg]

this installed well on my macbook pro, running os X 6.8, but it won't update the anti-malware.  in fact it hasn't updated it since 2011.  moreover, there are 2 mcafee logos in the top tool bar (the one with the date and time, etc.) --both logos say the same thing in "about mcafee."  i did have 2 versions of mcafee security on this computer, but i have trashed the older ones and (i think) all their ancillary files.  i have also emptied trash.

does anyone have any ideas about how to correct this?
