Verify that your virus scanner is working

The EICAR virus test is a harmless text file that is detected as a virus by most AV vendors. You can use it to verify that your local virus scanner is working (just copy the string into a plain text file), check to see if your email server scans for viruses (email yourself a copy), and test if scanners detect viruses inside archives (put it inside a zip file).

First, create a new text file and paste the following code into it :


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

Then save the text as a .COM file (any name will do, like eicar.com). To test that your antivirus is doing its job, you should try emailing the file to yourself as-is as well as zipped into an archive. If you just want to test your desktop scanner, right-click the file (again, you may as well try it as-is and zipped) and tell your antivirus program to scan away.

I tested the Eicar file against the free antivirus program Norton, and to my satisfaction Norton caught it, no problems. If you want to be sure that your antivirus program is actually doing its job, try the Eicar test file for yourself.
