test2.bat is :
""%ProgramFiles%\ESET\ESET NOD32 Antivirus\ecls.exe" /base-dir="%ProgramFiles%\ESET\ESET NOD32 Antivirus" /auto /log-file=c:\ecls.txt /aind"
batch file found on your site.
I just renamed it to simplify my work, because when I ran the original batch file of your site, I had the same result.
do you think I can run the scan with this simple command "ecls c \" ?
here the support where I found the batch file: https://support.eset.com/en_EN/kb2272/?locale=en_EN&viewlocale=fr_FR
