I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Well I'd start by checking for malware and viruses as they have been known to cause this issue. Malwarebytes is always a good starting point.
There is a registry hack that will disable the warning, but that just might be hiding a symptom of something more sinister.

From Microsoft:

1.Click Start, click Run, type regedit, and then click OK.
2.Locate and then click the following key in the registry:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer3.On the Edit menu, point to New, and then click DWORD Value.
4.Type NoLowDiskSpaceChecks, and then press ENTER.
5.On the Edit menu, click Modify.
6.Type 1, and then click OK.
Does it say that your C: drive is low on space?
I see the icon that you're pointing to in the "notification area" of your taskbar, but could you please provide with the actual warning? I also suspect the health of your hard drive as a possible culprit, but malware is my first go-to as well.

GarethPeart:  Thanks, I am scanning now and will post the results.  I'd prefer not to do the registry hack - I'd like to find the cause and fix.

arnold:  thanks for your reply.  The screenshot of "My Computer" in the pdf shows 87.1GB free on C:.  Is that what you are asking?
I was wondering what is the warning on the icon. I.e. does it say that you're running low on space on C:.  
When I used to get those, the disk cleanup always followed which does not seem to be the case in your image.

It turns out Norton Internet Security was the culprit:


The only reason I looked in Norton's direction was after double-clicking the warning icon and reading the title of the following pop-up did I notice the words "Liveupdate warning".

I would not have thought to do this without both arnold's and ogctech's direction, therefore they both get points.

Thanks for all of the replies and assistance.
