SonarScanner for MSBuild - Unhandled Exception

I’m using SonarScanner for MSBuild 4.3.1.
When “SonarScanner.MSBuild.Exe end …” is executed an unhandled exception “System.ComponentModel.Win32Exception: Access denied” is generated.
It seems that SonarScanner is creating the file “Windows\TEMP\489314d86c55a948a225789db7a93229.tmp”.
Panda Cloud protection is recognizing it as virus “W32/Exploit.gen” and removes the file, which seems to lead to the exception.

Could someone confirm that the file is generated by SonarScanner and that the virus report is a false positive?

With best regards,
