Well this is what a know so far, hope it helps... same thing happen to me last night. I checked for virus and spyware (with norton and windows defender) the notebook was clean, but the problem persisted.
Just this morning I wrote to HP Costumer Care, here is what they said:
"The issue could be due to corrupted operating system files, incorrect
internet settings, etc..
I request you to perform the following options on your notebook in order
to isolate and resolve the issue.
If the issue persists, then please perform the full recovery in order
to resolve the issue.
For more information about Using HP Recovery Manager, please refer the
below link :
Select the option Restore PC to original condition with the Recovery
Manager if Windows Vista cannot be accessed in the link:

NOTE: Clicking the link may give an error indicating it is
invalid. Copy and paste the entire link in a new browser window.
This should resolve the issue."
I haven't tried anything yet.
Also, I read on a forum that someone with the same problem turned off User Account Control and that solved the issue.
I'm going to try to change the folder options, then I'll try to turn off the Usser Account Control (which is pretty much an useless application) and finally I'll try the recovery.
The worst part is that since the message appears about every 8 seconds you don't have much time to work in the solution, try over and over again till you do it fast enough
