Thank you for your messages.
Please note that Microsoft has recently release an update for an issue with false positives which might be helpful in case if your antivirus software uses their databases (or refers to them). For more information you can refer to this page
. So in this case, please try updating your Viewer and Hosts to the latest version 220.127.116.11
using Simple Update
and please make sure to add your RU installation folders to the exception lists just in case as described here
In addition, please make sure that you have the latest updates for Windows installed - you can use the Check for updates
feature in the Windows Security Virus & threat protection
screen to check for the latest updates.
Please let us know if the issue still persists after installing the mentioned updates for Windows and Remote Utilities as well.
