Test your antivirus

How do I Test My VirusScan Installation?

simple:
After installing VirusScan, you may wonder(you should), how do I know if it's working? The answer is a "test virus".
The EICAR Standard AntiVirus Test File is a combined effort by anti-virus vendors throughout the world to implement one standard by which customers can verify their anti-virus installations.

Solution:

To test your installation, copy the following line into its own file, then save the file with the name EICAR.COM.

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

If VirusScan is running and configured correctly, when you try to save the file, VirusScan will detect the virus.
If VirusScan is not running, start it and scan the directory that contains EICAR.COM. When your software scans this file, it will report finding the EICAR test file.

Actually this file is NOT A VIRUS.
