I did a Google for "MCCWSA" and didn't get anything useful. Something is
running in the background and not shutting down gracefully. It could be
malware (always a strong probability when a Google search doesn't pop up
an answer for a name) or it could be something legitimate.
The first step is to determine whether your computer is completely
virus/malware-free. The second step, if the computer is clean and you
still get the error, is to do clean-boot troubleshooting to find the
culprit.
A. Step 1 - Malware scanning
Go through these general malware removal steps systematically -

Include scanning with David Lipman's Multi_AV and follow instructions to
do all scans in Safe Mode.

When all else fails, run HijackThis and post your log in one of the
specialty forums listed at the link above (not here, please).
B. Step 2 - Clean-boot troubleshooting

Standard caveat: If the procedures look too complex - and there is no
shame in admitting this isn't your cup of tea - take the machine to a
professional computer repair shop (not your local version of BigStoreUSA).
Please be aware that not all local shops are skilled at removing malware
and even if they are, your computer may be so infested that Windows will
need to be clean-installed. Have all your data backed up before you take
the machine into a shop.
