Avast keeps uninstalling my browser

[REDACTED]

I just discovered GhostBrowser-1.0.3.10_x32, and installed it on my hard drive . 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.
