Yup, good you mentioned this! But (as you suggest) let's not discuss each and every fake mIRC that is distributed; it doesn't make much sense to tell what versions are fake as new mIRC versions are only released from and with lots of information on our official website
http://www.mirc.com/ and the mirrors advertised on that website.
All and each information about mIRC and it's releases that is not available on our website can and should be considered fake.
