Thank you for the report.

This is a known false positive detection of Unchecky by the NOD32 antivirus.
We're working on getting this solved, and we hope that the false detection will be removed in a couple of days.

To clarify, the detection is a 100% false positive, i.e. Unchecky is not infected with a virus.
You can check the Virustotal scan page and verify that NOD32 is the only antivirus to detect Unchecky as malicious.

We suggest to whitelist Unchecky until the issue is sorted.
