Here’s something to think about: how often do you test your anti-virus software to ensure that it’s working properly? Using the European Institute for Computer Antivirus Research (eicar) test files, you can test the response of your anti-virus and anti-malware software. I currently have a ticket open with eicar to see how often they update the test files. I will post that information when I receive it. In the mean time you can check them out at the link below and try their test files.

Here is the response I received:
Hello,
there is no update needed, because the EICAR antivirus test file becomes
an industry standard. Please read the information on our website.
