Introduction :

Does your antivirus work the way it was intended to be ? If you think so, sometimes you may go wrong.
Some antiviruses may be handicapped or modified by the Viruses to not detect the viruses. In such cases, how do you detect that your antivirus is still alright ?

For such situations to occur, EICAR ( European Institute for Computer Antivirus Research ) and CARO ( Computer Antivirus Research Organisation ) have created a harmless test file that will help a developer or an end user to check whether the antivirus is really working or not.

If you want to test your antivirus, then this might prove to be a good testing method. You cannot risk yourself for testing your antivirus by using a real virus.

Whenever an antivirus scans this eicar file, then it should detect it as virus. Otherwise, it is out of order.

This test is not harmful... It does not risk your PC in any manner
