Slow Boot Up And Slow Operation

There are no real malware issues in your logs. The first area of concern that I would address is adding more memory. You really do not have what I would suggest as the minimum for Win 7 x64. Your logs show:
Installed Physical Memory (RAM) 2.00 GB
Total Physical Memory 1.74 GB
Available Physical Memory 572 MB

So you graphics card or other system devices are stealing from your installed memory base and thus leaving a smaller amount for your use. I would upgrade to at least 4 GB. Other than that I suggest that you try posting in the Software Forum for additional non-malware tips.

Since you are not having malware problems, it is time to do our final steps:

1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware.
2. If running Vista, Win 7 or Win 8, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
3. Now goto the C:\MGtools folder and find the MGclean.bat file. Double click ( if running Vista, Win7, or Win 8 Right Click and Run As Administrator ) on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
5. After doing the above, you should work thru the below link:
