I've got exactly the same issue without the error message. Did you manage to resolve it yet or find out anymore?

jfar.

To permanently get rid of those unchecked boxes open Regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Msconfig\startupreg and delete the entries there.

I'm pretty sure that Kapersky is causing your issue. This same problem has already come up serveral times before and the symptoms were the same with the high CPU usage. It only seems to occur on certain systems.

As I recall you can't just disable it, you have to uninstall it completely in order to fix the problem.

I had the same high cpu issue when I first installed AVG, which was resolved with a re-installation, so try that.

@Chev65
It's a good answer - I have Kasperky installed!! - I'll try a reinstall and report back.
I used Process Explorer to trace the problem and it seemed to point to plug and play being the problem. It seems to open several repeated processes in the thread and eventually blogs out.

Take a look at this screen shot and see what you guys think
