A very simple and shitty virus scanner.
antiVir [file]
Example:
antiVir infected
The infected file is a real virus that I found on github (I don't remember where). For safety, I damaged the file with the virus so that it wouldn't accidentally do any damage. main.mdb file with virus signatures I stole from https://github.com/Cisco-Talos/clamav
Note: You need to unpack the zip file before starting the program.
