System fix

It seems that whenever I log on to my laptop I have to do a fix for security and performance.  It usually takes 30 minutes to an hour and by the time it gets done I no longer want to be on my laptop.  I do not understand why there are so many fixes.  I am to the point I no longer want to use my laptop.   What is up with all the fixes, especially when my live updates are being done.  Any insight would be appreciated.
