Avast keeps uninstalling my browser

I just discovered GhostBrowser-1.0.3.10_x32, and installed it on my hard drive ;D. The problem is that Avast gives me a notice that Alexa.51 has been discovered and Avast deletes my browser :'(. Am I the only one who is having this problem, or is Ghost so new that Avast mistakes it for malware?

See attached below for General settings. Avast should not delete a file unless it is set that way.

Avast is likely blocking the execution of your browser because of these settings shown in attached file.
