In all cases so far, these have been false alerts. We always check the files before packaging them and the development machines are equipped with anti-virus software that is constantly updated. Before publishing a release, we additionally do a check with different anti-virus tools. To make sure our software is harmless you can check the files here: Virus Total.
A few times, the file uninst000.exe was detected. The file is part of our installer system (called Inno Setup) which is used by a lot of programs.

These false alerts normally disappear within few days. If you feel better anyway, you can keep the file in the quarantine for that time.
