Test Your AntiVirus Software
Creating A Test Virus:
Have you ever wondered if your anti-virus software is really working?
Would you like to see what happens when it detects a virus? Here's a
safe way to test your computer's virus protection that doesn't require
you to have a real virus.
First, open Notepad. Then copy and paste into it the text on the line below. (It should all be on one line.)
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
Then select File, Save, select All Files for the file type, then save the file as eicar.com.
Your anti-virus software may prevent you from saving the file as
eicar.com, which is a sign that it is working effectively. If it
doesn't raise an alert, try scanning the folder where you saved
eicar.com. To see what happens if you try to run a file containing a
virus, double-click eicar.com to open it.
Explanation:
The file eicar.com you have created is completely safe. It is not a
virus. It is a standard test file developed by the European Institute
for Computer Anti-virus Research (EICAR). All anti-virus products are
programmed to detect this file as if it was a real virus. Therefore you
can safely use it to test whether your anti-virus software works,
without fear of infecting your computer.
Conclusion:
If your anti-virus product should fail to prevent you from running the
file, it will simply display the text
"EICAR-STANDARD-ANTIVIRUS-TEST-FILE" in a DOS box. No harm will have
been done, but you should probably consider using a better anti-virus
product, because if it had been a real virus, your computer would by
now be infected!
