Official Builds Only

Download UltraViewer only from verified official channels you control on UltraViewer.io. Third-party repackaged installers may bundle unwanted software or modified binaries. Always prefer the publisher-signed executable from this download page once links are active.

MIT License (Community Distribution)

SHA256 & Digital Signature Verification

Antivirus False Positive Clarification

Remote desktop tools are often flagged heuristically because they enable screen control, file transfer, and background connectivity. Behavior similar to legitimate admin software can trigger generic detections such as "RiskTool" or "PUA" even when the file is clean.

  • Independent scans of official UltraViewer 6.6.124 reported 100/100 clean with no virus, spyware, or malware.
  • If Windows Defender or another AV quarantines the installer, verify SHA256 first, then add an exclusion only after confirming the binary is official.
  • Never disable antivirus permanently. Use vendor reporting tools to submit false positives when hashes match official releases.
