You need to report it as a false positive to your antivirus vendor so it won't affect other HM3 users with the same antivirus in the future, then remove the file from quarantine and/or reinstall the software and make sure to exclude HM3 from scanning by by your AntiVirus.
a) Open your Windows Defender (or chosen AntiVirus program) > History tab:
1) Select the files if they are from holdemmanager with that checkbox on the left side, then in the bottom right of the window click 'Allow Item'.
2) Start HM2.
b) If you continue to have problems:
- Export any custom HUD profiles from the HUD - HUD Editor using the 'Options' button.
- Uninstall any 3rd party security software bundles.
- Reboot your computer
- Please try to uninstall HM3 from your Control Panel - Programs and Features menu.
- Delete C:\Program Files (x86)\Holdem Manager 3\ if you see it.
- Download and install HM3 again from this link - https://www.holdemmanager.com/downlo...channel=stable
- Enable Windows Firewall's recommended settings through your Control Panel, turn off Windows Defender (unless you are using Windows 10, in which case it should be enabled).
- Install Microsoft Security Essentials (unless you are using Windows 10) for antivirus/malware protection and update it - https://support.microsoft.com/en-us/help/14210
Please let us know if that does or does not solve your issues.
