OTL took care of the stuff it was supposed to and ComboFix found some things that didn't show up clearly in OTL. It was mostly just junk, but it needed to be removed.
As for the slowness of the system, one of the things that can cause a slowdown is having two or more AntiVirus programs installed. They both use system resources to load which would cause a slowdown at boot up. OTL only showed Microsoft Security Essentials, but the ComboFix scan shows that McAfee VirusScan, or parts of it are still on the system also:

I have checked the original OTL log and the subsequent OTL logs and can't see McAfee listed in the installed programs. Do you remember uninstalling McAfee at any time, or did you just install MSSE over it?
I want to get a Security Scan log and see if McAfee shows up on it. After the scan, I want you to look in Add/Remove Programs in the Control Panel and see if McAfee VirusScan is listed as an installed program.
