Quick Clean finds 400 registry errors

Had the same issue, but worse; Quick Clean found about 3000 registry entries for deletion, and, since I've been using it for years (and trusting McAfee), I let it run. Big mistake! Couldn't print, couldn't open IE9, couldn't open QuickBooks, couldn't open Business Contact Manager for Outlook 2007! (So far - don't know what else won't work, yet.) And real time scanning wouldn't start. Just kept spinning and spinning....  MVT fixed the real time scanning issue on two (of 3) computers; had to reinstall/repair the other software that wouldn't open and uninstall/reinstall printer drivers on all 3. And the Internet Security 2013 update just makes everything run a little slower (McAfee does have a reputation as a resource hog...).
