Hello Terry, I apologize for the inconvenience caused. system There can be many reasons for the PC slowness. I request you to go through the following link http://bit.ly/1Raadle .

I have 2013 Premium security and PC Tune-up.  My license expires Jun 22, 2015.  I need to update. But PC tune-up and/or security is running in background and is slowing everything to a crawl.  It will not chnage settings like firewall and I can not get it to run or quit. what can I do?? With it running so slow, I cab not update the software to a new version because the firwall is set and  the PC runs to slow and connection times out.
