During the installation process, the "update.exe" file may trigger an anti-virus alert on certain devices. However, your computer is only alerting you as a precaution due to the built-in update feature available through your internet connection.

You can verify that the update comes directly from us and please rest assured - Talkia application is definitely not a virus, spyware or malware. This software update was designed to provide you with a better app experience as we frequently expand Talkia’s capabilities through new tools and features! 

The best way to resolve this is to teach your antivirus software that Talkia is safe. You can add Talkia to the exclusion filter inside the antivirus software itself to make sure that the software is recognized as part of your antivirus trusted zone.
