Ccleaner can't shut down Internet Explorer

I have a client that says her computer is slow. It starts then shortly after boot-up runs slowly. I have run the host of JRT/Adware Cleaner/ and Malwarebytes. Malwarebytes removed 1 item, JRT-17, ADW-0.  I also ran ComboFix and removed 1 items. I also ran Malwarebytes Rootkit Beta but it found nothing.

It still runs slow after the scans. When run Ccleaner to delete temporary files etc, Ccleaner says 'Must shut down Internet Explorer...' When I click OK, it hangs and cannot shut IE down.  Internet Explorer is not running explicitly so I think something is still on the computer.

Any help finding what ever it is and getting rid of it would be appreciated!

Go to Control Panel, Programs and Features, Windows Features and uncheck IE ("removes it"). Restart - you must.

Now try removing temporary files again. Any luck?

You can go back to the same place as above and Enable IE.  Restart again (you must) and IE will be back.

After it returns, I suggest you do an IE Reset. IE, Tools, Internet Options, Advanced and Reset. Reset the top half items.

Use Bit Defender Rescue CD (details and instructions here:

Check start up settings, services and running programs from the task manager. If you find something suspicious, let know!

It's better to refresh the OS instead of spending hours..

Do the following to speed up your PC:

Uninstall unwanted programs.
•Only use one Antivirus in real time mode,
•Check if new drivers has released by Official Website of your Computer Manufacturer and replace them
•Run Msconfig and select "Startup" Tab, then click on Disable All, apply, OK, restart the PC. now try to enable only one item and restart the PC again and test if that item is causing the issue.
•Run Disk Cleanup
•Run CCleaner to check and fix registry errors
•Run Disk Defragmenter

                                                                          * * * * *

if you still have speed problem on that PC then Create a new user account and switch into it and test it.

                                                                          * * * * *

Your last option will be Windows 7 Repair Install / Fresh install.

Run the following command before doing the scan. Even though you do not see IE it doesn't mean that it isn't running.
tskill iexplore

Open in new window

Thank you all for your comments. I looked in the System Logs and found more detail. My theory is Carbonite is the likely culprit since each time Internet Explorer stops working, Carbonite throws out an error.  I uninstalled Carbonite to see if there are any more issues and will check in with the end user in a few days.
