One option for those (including myself) who are concerned either about
another application hijacking the Prime95 communication link, or a Trojan
masquerading as Prime95 is to use an adequate firewall.  One application for
Windows PCs is ZoneAlarm (www.zonelabs.com), and it's free.  It blocks both
external access to your computer, and perhaps more importantly, only allows
the programs you approve to access the outside world _from_ your computer.
ZoneAlarm creates MD5 checksums for each program that tries talking to the
Internet, and thus prevents another program from calling itself "Prime95" to
gain access.  For a good discussion of available firewalls, see
http://grc.com/lt/leaktest.htm.
