This is Josh from Tech Support. We've identified the root cause of the issue you reported and are now working closely with several anti-virus vendors in removing their false positives on RU. At the present moment if you still encounter the issue again when using or downloading the files from our website, feel free to notify us.
No problem. Even if the file just gets quarantined, it still qualifies as a false positive. Make sure you update your windows defender and the issue should be resolved. Let me know if it still persists.
Portable Viewer flagged as Trojan: Win32/Rundas!plock
Thanks for the Report. We've reported the issue to Microsoft, they usually resolve false positives in a day or two. If you still have problems after an update or with the other RU modules. Feel free to notify us again.
Thanks for your valuable input. I'm with Tech Department and I can assure you that all other Remote Software programs in the market today faces the same issue as to ours, big or small. False positives from Google, Microsoft and all other A/V companies are all too common especially when a new version of a file is released. Since a new file version is unknown to these companies, this is usually the most common cause for files being flagged.
For future major version updates, we'll try to inform everyone prior to deciding to update to avoid any disruptions in your day-to-day activities.
We just recently contacted Microsoft in regards to the false positive, can you confirm if you're using the latest version of MS Essentials and try re-downloading/installing RU? If the issue still arises let me know.
