combofix self-exiting

I was at this place doing a malware removal job, but there was no internet connection. Usually I would just download the latest combofix at the time.

But no problem, I had an month old version on my flash drive.

I tried to run the versoin that I had, it said that it was outdated and (forgive me if details are fuzzy, I'm going from memory) it said something like Say Yes to exit, or no to run in reduced functionality.

It was all I had, so of course I said no to run in reduced functionality, but instead of running in reduced functionality, it exited itself and then deleted itself from my disk.

Why? Why did it not do what it said it would do?


Thanks

 

Well, I use a fresh copy when I can, but in this case I could not. But that doesn't change the fact that it did not behave the way that it said it would. Why?

 

Well, I was not able to do it. That's it. I'm doing a job, and I only get one shot at it. I already said, if I can, I use a current copy, but that was not possible in this case. That is is not current, is not a valid excuse for the program lying about its behavior.
It is not buggy, I have seen this exact same thing in my own personal experiments under virtual box at home.
