Quick clean lite is a very older version of mcafee products. There should be some remnants of the program still left under registry . Please run the removal tool from hereand restart the computer .
Reinstall your products from http://us.mcafee.com and you should be alright. If you need assistance in doing this, please feel free to contact our technical support chat technician from here and they would be assisting you .
