During weekend virustotal.com has detected irsasave260.exe (Save Message installer) as malware Trojan.Downloader.gen.h. This is a false positive alert. We have reported it to AV.
Upon installation start the installer (irsasave260.exe ) tried to contact our server to find out if there isn't any newer version of the product. If so it showed the latest product news, nothing else. And this seems to cause the problem with some AV (McAfee). They suspect that the installer contains some kind of malware - suspected of Trojan.Downloader.gen.h.
Today we changed our installer a little bit. We added a checkbox to the installer Welcome page to optionally disable that feature.
