Testing your virus scanner

Got a virus scanner? Quick! Copy and paste this line of text into a blank notepad file!

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

Saveit as Eicar.com. Put it on your desktop.

Cngratulations! You’ve just created the EICAR Test file for Virus Scanners! Let your computer sit for a few minutes, and see if it finds it (It will label it as a virus. It’s not, it’s harmless). Doesn’t find it? Scan the file manually with it. It should find it. All credible AV programs must react as if though it’s a real virus (It’s not).

Still doesn’t find it? Could mean your antivirus program is broken. You might need a new one. Try Avira AntiVir or Avast! Antivirus.

More info found here and here, and you can download it here (Scroll to the bottom, and try each one from the top row to test how your AV program reacts to them. The second one is it pretending to be another type of file, the third one it in a ZIP file, and the fourth one a zip file within a zip file with the EICAR thing in it).
