My PC is generally slow & poor video playback

Your logs are clean. I do see that you once had Webroot installed. We can clean that up:

* Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
If it is not on your Desktop, the below will not work.
* Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
* If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
* Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):

Code:

KILLALL::
Driver::
WRConsumerService
 
SecCenter::
{63671000-11A2-46DD-BADD-A084CABCDEAE}
{77E10C7F-2CCA-4187-9394-BDBC267AD597}
  
Registry::
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{02478D38-C3F9-4efb-9B51-7695ECA05670}]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Toolbar]
"{DBC80044-A445-435b-BC74-9C25C1C588A9}"=-

* Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
* At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
* You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
If it asks you to overide the prvevious file with the same name, click YES.
* Now use your mouse to drag CFscript.txt on top of ComboFix.exe

* Follow the prompts.
* When it finishes, a log will be produced named c:\combofix.txt
* I will ask for this log below

Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

There can be many reasons for slow performance. You may wish to try disabling your McAfee suite and seeing if that makes a difference. However, this is not a malware issue, so I suggest you post in the software forum for additional assistance. You should also be aware that adding more RAM may help you:

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

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /uninstall
     
     • Notes: The space between the combofix" and the /uninstall, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
4. If running Vista, 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.
5. Go to add/remove programs and uninstall HijackThis.
6. Goto the C:\MGtools folder and find the MGclean.bat file. Double click 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.
7. If you are running Vista, Windows XP or Windows ME, do the below:
   
   • Refer to the cleaning procedures pointed to by step 6 of the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore to create a new clean Restore Point.
8. After doing the above, you should work thru the below link:
