ewido's signature has changed after update....

Yesterday, after the online update of ewido, I found the name of ewido has been changed from "ewido security suite" to "ewido anti-malware". after I read this thread, I know it's normal: https://www.wilderssecurity.com/showthread.php?t=111485

Today, when I try to update again, my firewall (Look 'n' stop) said: "The application signature has changed, do you want to authorize it again?"

1. Is it normal?
2. Is it possible that ewido's signature be changed by a malware?

 

Hi,

You should accept this, this time too.

If one of our files was manipulated and the signature is not known to us you will be notified by our software or it will be simply overwritten with a valid version.

But I don't think that is was corrupted since we're updating our software from time to time and fixing some bugs, etc.
