Hi shehzad, and welcome to the forum

I am sure you will succeed after adding the parameter as Christian Peters suggested


In addition do not forget to disable real-time resident of your Antivirus (if you are using such) before testing

You can Search this and our old forum for “Eicar” (no quotes) there are tones of discussions

My regards

P.S. Just a note the future:

Please attach reports and provide info about your system as in Forum Posting Rules

You forgot to use the flag /a, /archiv to scan archivefiles.

Use command: a2cmd /f=c:\avscan\filestoscan\ /a
