Virus can seriously harm your computer. Well, here is a quick and easy way to test your antivirus. To check the performance of your antivirus here is the process called EICAR test which will work on any antivirus and was developed by European Institute of Computer Antivirus Research.


This test will ensure the thing that your PC is secure enough to compete the viruses or not. This process can be used by people, companies and antivirus programmers to test the proper functioning of the antivirus/anti-malware software without having to deal with the real computer virus/malware which can cause damage to the computer.

Note: Don’t be stupid! This test will cause NO DAMAGE to your computer even though the antivirus will flag it as a malicious script.


Here is a step-by-step procedure to test your antivirus.
– Open Notepad (shortcut key -> Windows+R, write Notepad and hit Enter)
– Copy the following script exactly into the notepad


– Now on saving rename the file from New Text Document.txt to “” (do include the quotations marks) In some cases the text file reported as virus too! (kaspersky detected the txt file)
– Save the file. (recommended on desktop)
– If your antivirus is running then it’ll immediately detect that file and will delete it.

In some other case if your antivirus is disable then run it. If it detects the file it means your antivirus software is doing well. Otherwise you may have to change your antivirus.

If you are interested to scan performance of your antivirus upto compression level , You can also place file in a ZIP or RAR file and run a scan on it also to ensure whether your antivirus can detect the test string in the compressed archive. Any antivirus when scanning this file will respond exactly as it will do for a genuine virus/malicious code.

About EICAR Test File
The EICAR test file (official name: EICAR Standard Anti-Virus Test File) is a file, developed by the European Institute for Computer Antivirus Research, to test the response of computer antivirus (AV) programs. The rationale behind it is to allow people, companies, and AV programmers to test their software without having to use a real computer virus that could cause actual damage should the AV not respond correctly. EICAR likens the use of a live virus to test AV software to setting a fire in a trashcan to test a fire alarm, and promotes the EICAR test file as a safe alternative.

AV programmers set the EICAR string as a verified virus like any other signatures. A compliant virus scanner, when detecting the file, will respond in exactly the same manner as if it found genuinely harmful code. Its use can be more versatile than straightforward detection: a file containing the EICAR test string can be compressed or archived, and then the antivirus software can be run to see whether it can detect the test string in the compressed file.
