Laptop problem: "Appropriate permissions"? (Edit: Gave up on DIY approach) Answered
#1 son has done "something" to his laptop (Sony Vaio VGN-FE31Z).
No matter what software he tries to start directly, he gets the message:
"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."
However, if he goes to "My Documents" and opens an existing document, the software opens fine, and if I type a link to a word document, then hit "Ctrl+click" the Safari browser starts up, but runs incredibly slowly.
Is there a way I can fix this myself?
There are no documents that need rescuing, but it would be nice if the software survived the fix.
EDIT: Since the general consensus is that he's gone and infected it with something, I think I'll take the laptop to be flushed and started over. Thanks everybody for the help, but no "best" this time.
FURTHER EDIT: The tech that fixed the computer for me stopped counting at 400 viruses and 40 trojans. It turned out that two pieces of anti-virus software were spending more time fighting each other than doing their actual job. Whole system flushed, and Avast installed.
