Seems like of I let them all run, my PC is too busy for anything else.
Just superantispyware is causing 100% CPU usage, and then the next
time I start my PC, Verizon Internet Security Suite says it has been
partially disabled and I need to click Fix it.
I do and it gets fixed.
And while starting up, the blue "Windows id starting" screen takes
several minutes to pop up the administrator icon.

So of these: Superantispyware, malwarebytes, Spybot S&D and Verizon
Internet Security Suite;
How best to used these tools daily to protect my PC while at the same
time not imapair its performance
