You have adware installed. See my Adware Removal Guide for help finding and removing it.
In addition, you have MacKeeper installed, which is a scam. See:
It is entirely possible that solving these two issues will fix your problem.
(Fair disclosure: I may receive compensation from links to my sites, TheSafeMac.com and AdwareMedic.com.)
In addition to everything Thomas has said which I agree with completely, the report says that Time Machine is not configure. I suggest that you implement a backup procedure for your Mac. Getting an external disk drive and configuring Time Machine is very inexpensive and easy.
In addition to what other people have said, the latest OS software 10.10 "Yosemite" does not run well on older machines with only 4 GB of RAM. I suggest you upgrade your RAM. See OWC: http://eshop.macsales.com/MyOWC/Upgrades.cfm?sort=pop&model=437&type=Memory
Memory upgrades for this machine are very fast and easy to do.
