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: http://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?
