Can't delete locked file

[umiwangu]

After getting my flash drive back from a friend, it had a Win32 virus on it. These are normally locked, and I usually just go into Get Info and unlock it. This particular file, however, doesn't let me unlock it. And since I can't unlock it, I can't delete it.

Any ideas?

Also, is there any easier way to delete locked files other than manually going into Get Info and unlocking them?

Thanks!

Drag it to the Desktop and unlock it.

And if I want to delete it from the memory stick?

Here's an Apple documented way to do unlocking from Terminal.

sudo chflags nouchg filename

Have you tried holding down the Option key when selecting Empty Trash?

I can't put the file in trash because it's locked. I can't unlock the file because the check box won't clear (it stays on "locked").
