Install Help: antivirus and security warnings

Windows · macOS · Linux · Android

Edda is new, independently built software. Some security tools block new programs they haven't seen many downloads of yet, whether or not the file is safe. This is called a "reputation" or "false positive" block. You can confirm your copy is genuine and clean in under a minute, then use the steps below to allow it.

The Windows installer is digitally signed (Windows shows the publisher as William Leifheit), and the macOS app is signed and notarized by Apple. Some tools still block a new release until enough people have downloaded it.

Only follow these steps if you downloaded Edda from edda.ink and the checksum matches. Never turn your antivirus off completely. Restoring or excluding the single Edda file is enough.

Verify your download

Each file below has a SHA-256 checksum: a fingerprint that changes if even one byte of the file changes. If the checksum of the file you downloaded matches, your copy is exactly the one we published.

PlatformFileVersionSHA-256Check it yourself
Loading checksums… If this doesn't load, the full list is at dl.volsungtechnologies.com/SHA256SUMS.

The VirusTotal link shows what 70+ antivirus engines say about that exact file. If VirusTotal says the file hasn't been seen yet, you can upload your downloaded copy at virustotal.com to scan it.

Older versions
FileVersionReleasedSHA-256

All checksums in one plain-text file: SHA256SUMS (works with sha256sum -c).

Check the file you downloaded

Windows (PowerShell)

Get-FileHash "$env:USERPROFILE\Downloads\edda-setup.exe" -Algorithm SHA256

Windows (Command Prompt)

certutil -hashfile "%USERPROFILE%\Downloads\edda-setup.exe" SHA256

macOS (Terminal)

shasum -a 256 ~/Downloads/edda-latest.dmg

Linux

sha256sum ~/Downloads/Edda-latest.AppImage

The result should exactly match the checksum in the table above. If it doesn't, delete the file, download it again from edda.ink, and contact us if it still doesn't match.

Download straight to a folder on your computer. A copy in a OneDrive, Dropbox, iCloud or Google Drive folder can be changed or only partly synced, which also changes its checksum.

Browser download warnings

Chrome

Open Downloads (Ctrl+J, or the download icon in the toolbar), find the Edda file and choose Download suspicious file (in some versions Keep).

Microsoft Edge

If Edge says the file "isn't commonly downloaded": in the downloads panel, hover over the file and select …, then Keep, then Show more, then Keep anyway. If Edge offers to report the file, you can report it as safe. On a managed work PC the Keep option may be switched off by your IT department.

Firefox

Open the Downloads panel (the arrow in the toolbar), click the arrow next to the Edda file and choose Allow Download.

Windows protections

SmartScreen: "Windows protected your PC"

Click More info, check that the publisher shows William Leifheit, then click Run anyway.

Microsoft Defender

  1. Open Windows Security and select Virus & threat protection.
  2. Under Current threats, select Protection history.
  3. Select the Edda entry, choose Actions, then Restore (or Allow on device, if that is what you see).

To stop it happening again, add an exclusion: Virus & threat protection settings, Manage settings, then under Exclusions Add or remove exclusions, Add an exclusion, File, and choose the Edda installer. (Restore help · Exclusion help)

Smart App Control (Windows 11)

Smart App Control only runs apps it trusts, and Microsoft provides no way to allow a single app. Because Edda's installer is signed, Smart App Control usually allows it. If it still blocks Edda, the only workaround is to turn Smart App Control off (Windows Security, App & browser control, Smart App Control settings).

We don't recommend doing that just for Edda. On Windows 11 with updates from spring 2026 or later you can switch it back on afterwards, but on older versions turning it off can't be undone without resetting Windows. Please contact us first and we'll help you find the best option. (Microsoft's Smart App Control FAQ)

Third-party antivirus

Choose your security software. Each one has steps to restore the Edda installer from quarantine and to allow it from then on.

McAfee (LiveSafe, Total Protection, McAfee+)

Restore from quarantine

  1. Open McAfee. If the alert is still on screen, its quarantine link takes you straight there.
  2. Open My Protection (in older versions: Navigation, then Quarantined and Trusted Items).
  3. Click Quarantined items, select the Edda file and click Restore.

Allow or exclude the file

  1. In My Protection, open Real-Time Scanning.
  2. Under Excluded files, click Add file and choose the Edda installer.
  3. McAfee drops an exclusion when a file changes, so a newer Edda installer may need to be added again.

McAfee updates its menus often. If your screens look different, the official article above has the current steps.

Work or school computers

If your computer is managed by an IT department (for example with CrowdStrike, SentinelOne, Microsoft Defender for Endpoint or Trellix), you can't allow software yourself. Ask your IT team to allow the Edda installer and give them its SHA-256 checksum from the table above.

macOS

Edda for macOS runs on Macs with Apple Silicon (M1 or later). The first time you open it, macOS asks you to confirm an app downloaded from the internet: click Open.

If macOS says Edda "can't be opened" or that Apple could not verify it:

  1. Click Done on the message.
  2. Open the Apple menu, System Settings, Privacy & Security, and scroll to Security.
  3. Click Open Anyway next to the Edda message (it's there for about an hour after you tried to open Edda), enter your password and click Open.

You only need to do this once. (Apple's instructions)

If macOS says Edda "is damaged and can't be opened", open Terminal and run this, then open Edda again:

Terminal

xattr -d com.apple.quarantine /Applications/Edda.app

Linux

Check the checksum with sha256sum as shown above, then make the AppImage executable and run it:

Terminal

chmod +x ~/Downloads/Edda-latest.AppImage
~/Downloads/Edda-latest.AppImage

If it doesn't start, your system may need FUSE for AppImages (on Ubuntu 22.04 and later: sudo apt install libfuse2).

Android

Edda for Android is installed from the APK on your download page. When you open it, Android asks you to allow installs from your browser or file manager: allow it for that app. If Google Play Protect warns about an unknown app, choose More details, then Install anyway.
