Here we have 6 ways how you can safely test your antivirus to see if the real time protection is truly enabled and working to protect your computer against viruses. A few antivirus researchers have come up with a harmless file that is detected as if it were a virus and is distributed at EICAR.

So in short, the EICAR antimalware test file does nothing and is absolutely harmless even if it is run on the computer. If your antivirus real time protection is working, it should automatically detect the EICAR as a threat and remove the file from your computer.

A harmless simulation will let you test 10 different types of infection scenarios. Another good option is the SpyShelter Security Test Tool that can be used on live systems, and comes with 6 separate modules, with tests ranging from keylogging, webcam capture, keystroke encryption, clipboard and screen capturing, sound recording and overall system protection like registry access and writing to startup folder.

It is possible of course to compress the fake-sample within an archive to make the task harder for the antivirus, maybe by adopting a double or nth subsequent compression strategy to mimic a technique particularly popular nowadays among malware writers, used to camouflage their own work with ten of different compressions of the executable code.

Using real viruses for testing in the real world is rather like setting fire to the dustbin in your office to see whether the smoke detector is working. Such a test will give meaningful results, but with unappealing, unacceptable risks.

Since it is unacceptable for you to send out real viruses for test or demonstration purposes, you need a file that can safely be passed around and which is obviously non-viral, but which your anti-virus software will react to as if it were a virus. If your test file is a program, then it should also produce sensible results if it is executed.

Also, because you probably want to avoid shipping a pseudo-viral file along with your anti-virus product, your test file should be short and simple, so that your customers can easily create copies of it for themselves.

The good news is that such a test file already exists. Agreeing on one file for such purposes simplifies matters for users: in the past, most vendors had their own pseudo-viral test files which their product would react to, but which other products would ignore. The Anti-Malware Testfile. It is safe to pass around, because it is not a virus, and does not include any fragments of viral code. It is also short and simple — in fact, it consists entirely of printable ASCII characters, so that it can easily be created with a regular text editor.
