Hi,
For information, I've downloaded https://github.com/paintdotnet/release/releases/download/v5.0.1/paint.net.5.0.1.install.anycpu.web.zip et my Trend Micro Security Agent alerts me of a potential ransomware when i run the setup.
SetupDownloader.exe is the suspect file. Probably a false positive but virustotal.com show me : VirusTotal - File - 73ca46db0349f8211e4fda2c8cec4241fb3cc1ef605e2dc39c03252b20a8570b (MaxSecure ? strange results)
So i've downloaded : https://github.com/paintdotnet/release/releases/download/v5.0.1/paint.net.5.0.1.install.x64.zip and I didn't get any warning.
if anyone else has been in the same situation...
Cheers
