Buffer overflow attack

[Peter5]

Hi,

I hope this is that right place to post.
I am a user of Comodo Internet Security (version 5), and when i was installing Astroburn free i got this pop up, and when i starting using i got a new pop up (screenshot).
No problem i just skipped the application, because i know it was a safe file, but i just wanted to let you guys know.
Maybe you can do something about this, if you confirm it is really a problem.

Many thanks
