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 - the Pyks 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 Pyks's capabilities through new tools and features!
The best way to resolve this would be to teach your Anti-Virus Software that the Pyks is safe. You can add Pyksto the Exclusion filter inside the Anti-Virus Software itself to be sure the software is recognized as part of the Anti-Virus's Trusted Zone.
