Thank you for your prompt response. Indeed the total virus test is negative on ekag20nt.exe located in the Kamo directory. However, you should warn your customers that this version of the program is safe. Indeed, on the link https://www.file.net/process/ekag20nt.exe.html, this program is considered 42% dangerous. Other links received after Google search on this program consider it to be risky, and to watch out for, a link describing it as a keylogger.
You can understand that after my bad experience with Avast and especially with the Avast Antitrack Premium utility, there was reasons to wonder, Kamo strongly resembling Avast Antitrack Premium. Also knowing that your company has been taken over by Avast.
So I resinstall Kamo on my computer, and I'll use it with caution.
