EICAR Test

The EICAR test was developed by the European Institute for Computer Antivirus Research (EICAR) to provide a safe, easy way to test whether your antivirus software is doing its job.  All that's required to perform the test is to download the eicar.com file and double click on it like you are trying to open it.  If the antivirus software on your computer is working, it should detect it as the EICAR Test Virus.  Of course, it's not a virus but instead a harmless 70 byte file that most or all antivirus software programs are supposed to detect for testing purposes only.  It will not do any harm at all to your machine. 

Additionally, a zipped (compressed once) version and a double-zipped (compressed twice) version are provided to see if your antivirus software can detect it in compressed format.

How to perform the test

  1. Make sure that your antivirus software is enabled.
  2. Follow this link to the EICAR TEST VIRUS PAGE.  At the bottom of this page are four links to download different versions of the test file.  They are a .COM (executable), .TXT (text), and two zipped files (.ZIP) that contain the Eicar.com file (the second is double-zipped).   Try downloading these files.  If your Antivirus software is working, it should immediately detect any of these files as the "EICAR Test Virus".
