This is being investigated. We will provide an update after the analysis is done.
This might more information than you care to read, but wanted to give you all the context:
Is there any chance that you have the original installation package for this software?
In our research, we have been able to find that most likely this is installed as a bundle with another application installation. We found an installer that installed an application very closely related to this ‘zoomex’ . In that installer, the user was able to opt out of the installation and not have it install. If we did not opt-out, we were easily able to be remove it through add/remove programs. The problem is that we were NOT able to get the actual ‘zoomex’ installer, so we cannot verify if the actions are the same for both.
Regarding the cleaning, it appears that we are able to remove this dll with a detection so I do not suspect that we are failing to clean but rather there is another component that is restoring this dll. Hence, getting the install package will also assist in determining why the dll re-appears.
