Hi Mike,
as others have suggested, AP decoding will raise the probability of
false decodes a little. One thing you can do to reduce the false decode
probability is to ensure the DX Call filed is cleared when you are not
working or attempting to work another station. You can check the option
in "Settings->Reporting" to clear it automatically after logging a QSO,
for abandoned QSOs you can use the F4 or ESC shortcut keys to clear the
DX Call, DX Grid and generated messages. The reason that clearing the DX
Call filed helps is that AP decoding is context sensitive and with a DX
Call field populated the decoder will hypothesis that messages that
cannot be decoded with FEC alone contain that DX Call. When the DX Call
field is cleared only CQ is hypothesised which will reduce he
probability of false decodes.
False decodes are rare but always possible because of the stochastic
nature of the decoders and the requirement to decode the weakest signals
possible. You also have the option to disable AP decoding, and reducing
the decoding depth which will also reduce the false decode probability
with some lose of sensitivity.

Mike,
which mode are you monitoring and on which band?
