AE CS6 bug: Can't use any shortcut that includes the C in it

Question

A while ago I started having some issues In Illustrator CS6, where I couldn't copy and paste from one document/application to another, the issue later ported itself to AE and not much after that anything including the C key stopped working. For example I can't copy, pre compose or create a camera using shortcuts.
After a lot of troubleshooting I was able to isolate a preference pane who was causing the Illustrator issue, I removed it and AI went back to normal, I assumed After Effects would be fixed too but unfortunately that's not the case, I still can't use the C key.
I ran Onyx thoroughly, trashed AE's prefs, removed some recently acquired scripts, removed some login items and trashed those prefs also (I read a thread that mentioned those items could be causing odd behaviors).
I carefully compared my setup against my laptop, which also has AE CS6 installed and working perfectly, I have the same scripts, the same preferences and the only login items not installed there are the ones that's are grayed out in my imac, so I can't delete them.
If someone can help with this I'll be very grateful, I'm wasting a lot of time trying to solve this thing and I'm very used to using said shortcuts to increase my workflow.
Thanks.

I quit a few other components, a small utility called Shortcut (isn't that ironic?) and another one called MacAppBlocker,
I still can't pre compose any layers using command-shift-c
I was able to create a camera using command-shift-alt-c, after several tries, sometimes it worked, sometimes it didn't.
I was being able to copy and paste across different programs and layers all sorts of objects, UNTIL  I opened Illustrator and copied a path, then I pasted it into a solid in AE.
The next time I tried to copy something else, my clipboard got stuck with the path from Illustrator, EVEN inside illustrator.
Greg, as you can see from this thread:

This is an aknowledged bug from Illustrator, but as I have discovered in the past few days it's affecting everything systemwise, what are the possibilities that the only shortcuts that are failing are those that contain the combination of command-c? And like I said, it starts missbehaving right after I copy a path in Illustrator, not before.
Alright, after some further testing, here's what I found:
I removed (completely deleted) from my computer a small piece of software called WD Quickview, right after I was able to precomp and create cameras in AE.
I still have the copy/paste issue from Illustrator, right after I copy a path, the clipboard goes haywire system wide.
The strange thing is that, such program, WD Quickview has been installed on my computer for over a year now and never had any trouble with it, moreover, I'm not entirely sure how am I going to be able to get into the drive that uses that program (WD force-install that thing with their new drives that come with a new unerasable firmware).
Coincidentally, I haven't plug the drive at all this week, so perhaps the program went crazy when it couldn't find the drive?
