How to test the functioning of your Antivirus
Do you think that you are protected against antivirus even if you
have an antivirus installed? How would you know that your antivirus is
working properly without testing it? So its important to test your
antivirus after installing it in your PC.
The process of testing antivirus is known as EICAR test developed by European Institute of Computer Antivirus Research. This process can be used by people, companies and antivirus programmers to test the proper functioning of the antivirus/antimalware software without having to deal with the real computer virus which can cause damage to the computer.
Here is step by step procedure to perform this test.
1. Open a notepad file.
2. Copy the following code exactly into it and save the file.
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
3. Rename the file from ‘New Text Document.txt’ to ‘myfile.com’.
4.Run the file.
If your antivirus is working properly then it should display warning message and immediately quarantine the file. If not then you should reinstall the antivirus.
Antivirus programmers set the EICAR string as a verified virus like any other virus programmes. So an antivirus, when detecting the file, will respond in exactly the same manner as if it found genuinely harmful code.
You can also place the myfile.com file in a ZIP or RAR file and run a scan on it so as to ensure whether your antivirus can detect the test string in the compressed archive. This test will cause no damage to your computer even though the antivirus will flag it as a malicious script. Hence it is the safest method to test the proper functioning of any antivirus.
