I was recently introduced to Speedy PC Pro, and their "Advanced Tech Support" that involves throughly searching out your computer for all unnecessary processes left running (I know as a programmer that Windows was based on Unix, and Unix is notorius for leaving "zombie" processes running), and everything else that can slow down your computer. It does registry cleaning, etc. They do this by remotely taking control of your computer and performing all the maintenance that a computer pro would do for you in a computer shop. (I used to do this kind of thing myself when I worked as a computer programmer for MV Software.) It takes several hours. They also install what they call MalwareBytes, which they claim is superior to Norton, McAfee, etc. The fact that my old software (Wowway's F-File) claimed I had a firewall, but that firewall did not interfere with their technician taking remote control of my computer, shows how ineffective that supposed firewall was. The technician told me usually he would have to get passwords from me, etc., to get around a firewall.
The resulting improvement in my computer functioning was significant.

If you want to check on Speedy PC Pro, etc., here is a good reference: http://consumersguides.org/speed_up_soft...eviews.htm
Notice Consumer's Guides
rates Speedy PC Pro as their top choice.
The full service does cost a couple of hundred dollars. With that you get eligibility to have the search and cleanup service done for you three more times in the coming year, if you need it.
