I have been working on this for 2 days now. When I try to run some exe files (even when run as .com or .src) on one of the accounts (administrator) windows returns "windows cannot access the specific device! path, or file. You may not have the appropriate permissions to access the item.". I have run every scan I could think of (strart with rkill.com then Adwcleaner Malawarebytes OTL Rougekiller....). They do not return any nasties.
What makes me belive that it is corupt profile - all works on in safe mode or in new profile I have created.
Is there a way fix this??
