It is well documented that McAfee often interferes with many functions,
presumably including clean booting. I remember once starting a PC that
had McAfee installed in Safe Mode and McAfee was *still* running! You
might need to use AutoRuns to configure a "cleaner" clean boot:

Also, you didn't answer the other question concerning malware; that
*always* needs to be ruled out first.
