I no longer have something called "cmd" [View All]

[Tangerine LaBamba]

I'm a Comcast subscriber, so I get free (yeah, right) McAfee Security Suite. I have Windows XP, Professional, and I use Firefox.

I am only slightly computer literate, so please be kind.

The other day, the McAfee Update Window popped up and it said "You need to reinstall McAfee Security Suite."

To make a long story short, I went through a few Comcast and then McAfee technicians - very nice folks - but what was eventually revealed is that I have no "cmd" thing, whatever it is.

The McAfee technician told me to go to "Start," then "Run," type in "cmd," and nothing happened.

Can anyone help me fix this? I'm no longer able to download updates. This is troubling.

I've never posted here before, so I thank you in advance for whatever help anyone might be able to give me, and please excuse the fact that I'm driving with a Learner's Permit..................
