This file is known as EICAR Standard Anti-virus Test file, and it is also detected by several other anti-virus products in a similar manner.

To create the EICAR test file, use any text editor to create a file with the following single line in it:


save the file to any name with COM extension, for example EICAR.COM. Make sure you save the file in standard MS-DOS ASCII format. Now you can use this file to show what it looks like when a virus is detected.
