Its just the file packer, There is no virus.

Very cool game!
Some quick suggestions (more later, hehe);

~ mission briefing!

~ How about mouse control too? Couldnt get it to work.

~ Configurable keyboard controls. Didnt like the defaults.

~ I found it non intuitive to use the radar to navigate
to enemies. Perhaps the radar maps pan could always match the
choppers pan instead of remaining static.

~ arrow on radar edge to next/closest enemy/waypoint.

~ I couldnt get the boats to explode, so I wasnt sure they were
defeated?

~ How about a "pull up" warning when you get too close to the
ground, or/and dying (you get 3 lives right?) if you hit the
ground to hard/fast?

~ I would like to see AA missiles (not "real" fast ones!) and
they should generate a trail and be somewhat easy to avoid!

~ Alerts/warnings and alarms from the choppers computer!

~ More and bigger explosions, havoc, chaos, action!

I really like this game, great job! Hope you upload a new demo
with the mission panel!
