Any ideas on what I need to do? I am running Windows 7 Home Premium 64bit on a Lenovo Ideapad Y550.
Castman, it sounds like your computer has some serious issues. Before installing and running any program that claims to speed up and clean up, I'd want to know what's wrong with my machine and how/why it got that way. It sounds like you still have malware on the machine. "Malwarebytes didn't detect much"; "I found a trojan with Security Essentials"; "after removal problems persist"; "tried running chkdsk but it cancelled".
Do you have a restore point
that goes back to a date/time prior to when all these issues first appeared? If yes, use it. Then update Malwarebytes and run another full scan. If you don't
have a restore point run another full updated Malwarebytes scan anyway. If Malwarebytes comes back clean use other scanners just to double check because no antimalware product is 100% effective 100% of the time.

If your computer still comes back clean try running check disk again. If it still fails you may have some damaged or corrupt system files. Run a System File Checker scan from an elevated command prompt (Option Two.) SFC /SCANNOW Command - System File Checker
If the scan finds any issues run the scan three times rebooting in between each scan. Please post back and let us know what you've done and what the results are.
