From November. 1, 2020, Google marked our website as unsafe site because they considered iBackup Viewer for Windows is kind of unwanted or malware. We immediately checked with popular antivirus software like Malwarebytes and Microsoft Windows Defender, it was true the installer exe was treated as some kind of malware because of the custom icon used for the installer package. When we removed the option, and rebuilt the installer both passed the tests. And also get all passed by virustotal [https://www.virustotal.com/gui/url/1d0bcc901bf054b77d7b0212ffb612a91d7938fbc49a7c6825e8f76b206af4ed/detection]. The entry executable file 'iBackup VIewer.exe' has been tested with Microsoft Windows Defender and Malwarebytes. But 7 engines on VirusTotal treated it as different kinds of risks. We then created a clean windows 10 system and downloaded & installed Visual Studio 2019 community, then created a simple console application with just one line std::cout << 'Hello World!n'; some antivirus engines also treat it malware, use different compiling options and linking options may lead to different results. Not sure how these antivirus software work, but this is the truth they always treat a simple program as malware.
