. Test your antivirus software is active or non active

To test your antivirus in full safety, you can use the file of Eicar test. This file is detected as a virus by the antiviruses but it is not one, it does not contain any viral code. If the false virus is detected, it is that your antivirus is active and protects you.

Open Notepad
Then recopy the following character string in the Notepad:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*


Now save it and scan it by ur antivirus software..
If your antivirus is correctly activated, it must then alert you instantaneously presence of the Eicar virus.
Then ask your antivirus to remove the file. In my case I had installed BitDefender Anti Virus and file was recognize and removed automatically without any additional action from me.
