How can I test virus scanning software?

By using the "EICAR STANDARD ANTIVIRUS TEST" file. It's actually a legitimate MSDOS program, but it's all text, so you can just type it into a text file or an email. It's all ASCII, so it needs no encoding:
 
  X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*   
 

It's not really a virus - it won't hurt your system - but any anti-virus program should catch and report it.

Unfortunately, some will remove it too, which can cause problems for programs that use an EICAR file to be sure their built-in scanning is working correctly. If you have an app that needs an EICAR file, be sure to exclude at least the directory where it lives from any other virus scanning.
