When antivirus flags a new OFDownloader installer, check the published hash on the trust page before you quarantine it

A new desktop or Firefox build can trigger a heuristic alert. Before you quarantine the file, compare its published hash with the notes on the official trust page.

Open OFDownloader (by SaveMyDayApp) trust notes next to the download, then follow the verify-installer guide against that exact installer.

If the hash matches the published notes, keep the file and mark it as allowed in your antivirus; if it does not match, discard it and re-download from the official site.
