The correct operation of F-Secure anti-virus products can be tested with a special test file. This is a dummy file which is detected by exactly like if it were a virus. 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.
Naturally, the file is not a virus. When executed, EICAR.COM will display the text 'EICAR-STANDARD-ANTIVIRUS-TEST-FILE!' and exit.
