64bits : Windows cannot acess the specified device, path or file

[jasty]

Hello

Everything was ok, then I tryed to open a TXT file, and I had this error :

"Windows cannot access the specified device, path or file, you may not have the appropriate permissions to access them."

Then I tryed another TXT file : same
Then I tryed to launch firefox : same

I had to reboot, and now everything is fine again, but im really wondering why it happened, and if it will hapen again

Its a laptop i bought few days ago, and I only installed avast, zonealarm, and made windows updates : it should be clean
I only have one account on this computer


What should I do ? is it a virus already ?
Thanks for you help
Alex

Avast and Zonealarm? Is that 2 antivirus programs? If so you should only run one.

I would suspect ZA as the culprit.
