Do you want to test your antivirus software to check whether it alive or dead?

First you need to create a virus to test your antivirus software.

Creating a virus?! Yes, I mean it. Here are the steps to create a virus. Don’t worry, this will not harm your computer. If you execute the file, it will print EICAR-STANDARD-ANTIVIRUS-TEST-FILE! and then stop.

Steps to create your own virus :

  • Paste the below text in a text file.

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

  • Save the file as myvirus.exe in desktop.
  • Within few seconds, your Antivirus will identify this file and take actions(delete/quarantine) on it.
  • If it is done, then you can conclude that your antivirus is Alive.
  • If your antivirus software does not find this file then it is time to change/update your antivirus.

The file created above is called as EICAR Standard Anti-Virus Test File which was developed by European Institute for Computer Antivirus Research.

This file was developed to test the antivirus softwares without have a real computer virus.

    That is not a virus nor does it mimic one. Many antivirus vendors have designed their viruses to pick up this thing (pioneered by eicar) as a virus. In fact some like malwarebytes and superantispyware dont detect it at all. This is done by antivirus so that people can check if their protection is working. If uwant to simulate a virus, use the trojan simulator.

    Kaspersky is not bad or useless. It is not detecting the EICAR Test file because its so intelligent to identify such a ‘fake virus’
