After installing your favorite antivirus, you may logically wonder, 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.
To test your installation:
1. Open Notepad or any text editor.
2. Paste this script:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
File size will be 68 or 70 bytes.
3. Save the file as EICAR.COM
Use "Save As" and choose "All Files" as file type before saving.
Note that upon saving your antivirus software should detect the file as a virus.
Note that this file is NOT A VIRUS.
Delete the file when you have finished testing your installation to avoid detection.
This will not cause any harm to your system.
