Hello Andras. Thank you for your patience. My name is Shawn, and I will help you.
Specific to your concern, command line scanning is an available feature in AVG Internet Security, https://is.gd/UvRRGL, however it is not available in AVG Free AntiVirus.
I trust this information helps clarify your concern. Regards, Shawn
