What do these look like? Are they the ones with a raised line across the
head of the screw?
They look like a Torx screw head turned inside out. Imagine something
between a pan head and a round head (ie slightly domed) with six small
notches in the edge. The sides are sloping/curved and they're usually
hardened, and the edges of the notches are slightly rounded off so you
can't get a grip with pliers. There's a picture at

Ok, these are also known as "external line head" screws. Some people also
refer to the removal bit as a "gamebit".
The 33 piece security bit set does not contain bits to fit these, but MCM
and many other companies sell them.

In my experience nothing will grip those other than
the right tool. Even
the well known kludgers tool, 'Mole Grips', just spring off....
When all else fails, why not use a very strong epoxy to "weld" a piece
of metal, or a bolt, screw, etc. onto the heads of these idiotic
security screws, and then just unscrew them by putting a tool onto the
attached piece metal, screw, bolt, etc.? Ok, it's a kludge. but it
would work. Of course, if you're trying to get something like your
cable TV company-owned cable TV converter box open just to have a look
around inside (e.g., to make sure there's no microphone, etc. in there
- it's residing in your house, so, for your own well-being you have a
right to open it up and inspect it), then you probably don't want them
to know you've tampered with the screws... of course, you could
always use a tool to carefully grind and polish away proof of the
attachment once reassembly is complete. :-)

Why don't you just take a very small [such as dental] burr, and just cut a
slot for a screwdriver?
