Well I see some issues that need correction, however before you do ANYTHING there is no evidence you backup your Mac. This is short sighted and will result in lost data. If I am correct, please get yourself an external HD such as a OWC Mercury Elite Pro and use Time Machine to backup. If you are not familiar with TM please read Back up your Mac with Time Machine!!!

After you have a backup please do the following:

The best antivirus, cleaning app, and overall maintenance app for Mac OS is Mac OS itself. All you need to do with Mac OS to keep it secure and running well is to keep it up-to-date and do periodic (about 1x per week) restarts. Other than that, leave it alone. Adding third party antivirus, cleaning, security and other types of maintenance apps to Mac OS adds no additional level of security. The only thing these apps do is have the opposite affect users want. They make Mac OS slow, unstable, generate odd behavior (much like you are experiencing) and make Mac OS appear buggy.

Please locate the developers uninstall instructions for CleanMyMac and follow to the letter. Then restart in Safe Mode per the directions in Use safe mode to isolate issues with your Mac  and then restart normally.

Finally, please do the following:

• Uninstall all HP software, put in the Trash and empty the Trash.
• Please reset the printing system per Reset the Mac printing system to solve a problem
• Next, follow the instructions in Adding a printer
