Could you please let us know if the detected file is a custom installation package configured via our MSI Configurator Tool? If this is the case, then please note that our vanilla Host installation package does not have these detects, please see here. In cases when a custom installer is detected, we recommend that you add the directory with the file to your antivirus's exception list and then report a false positive as described here. We will surely contact Avast regarding this detect, however, please note that they will more likely reply and assist their current existing customer. Moreover, they will most likely request you to send the detected file for the analysis, so that they can remove the false positive.
One more thing that we can recommend in this case is that in case if you've selected the Legacy Configurator option when configuring the installer, please try generating the installation package once again with the Online configurator option selected instead as it provides you with a digitally signed output file.
Please note, that unfortunately, our assistance with antivirus software related issues is limited. If Remote Utilities is falsely detected and/or removed from your system by antivirus software, please contact the antivirus software vendor. We do not have direct control over how Remote Utilities is treated by third-party security software. For more information please see our Support Policy. Sorry for the inconvenience.
We are not responsible for poor code and quality of antivirus software vendors, especially noname vendors who are not even bothering responding to false positive reports. Antiviris software industry is in dismal state nowadays, they bring more harm than good. I wouldn't even take them and their 'detections' seriously, they have nothing to do with real security.
I created the host using the Online configurator ➔ One-Click package. I just created another one now which didnt get flagged by avg and avast like the old one, if it got flagged i'll report a false positive to the antivirus.
