Test Your Anti-Virus Program
Do have an anti-virus program. How can you test that it works?
This is a good question and it is wise to familiarize yourself with how your anti-virus software behaves when it detects a virus, before it really happens. One quick way to do this is to use the EICAR Anti-Virus Test File. This is a test file that will cause no damage to your system and still allow you to test if anti-virus tool is awake.
Here are some steps:
1. Open a text editor (e.g. Notepad)
2. Enter the following text in it:
“X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-T
EST-FILE!$H+H*”
(Without The Quotes)
3. Save the file as EICAR.COM on your desktop.
4. Open DOS and try to execute this .COM file (or simply double-click the file on Desktop)
If your anti-virus software is working properly, it will warn you that a virus has been detected when you attempt to run the .COM file.
To be double-sure, zip this file, and then try double-clicking on the ZIP file to see if your AV tool recognizes viruses inside ZIP files. You can also send this file to yourself as an attachment, just to verify if your AV tool has command of email cleanliness.
Thank You.

Kaspersky didn’t catch it in mine:
dell d820
core 2
xp sp2
Kaspersky 6.0.2.614

Hmmm, then you should change antivirus maybe.
Use nod32. It’s my favorite.
Thanks.

NOD32 didn’t catch mine and Windows (?) flags as illegal instruction.
March 9th, 2008 at 3:44 am
I have AVG & Avira Anti-Virus
Avira found it first.

Avast nailed it when I tired to save it! I didn’t even get a chance to double click it.
March 9th, 2008 at 5:53 am
avast! Home Edition didn’t catch it.
March 9th, 2008 at 7:15 am
NOD32 wouldn’t let you even save it!
I love NOD32, now I love it even more.

Worked in Bitdefender. The right string however is:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-
ANTIVIRUS-TEST-FILE!$H+H*

Brian D. Lester: Maybe you should update your Nod32.
Nitin: You just copied the string that is allready posted.
For the rest, I suggest trying to update your antivirus or downloading a new one. Send me a msg from the contact form if you want me to give you a full antivirus.
Thank You.

No problem. Avira caught it as I saved the file.
March 12th, 2008 at 4:34 am
Yep, avast! got it before I was allowed to save it.

Linux didn’t know how to run it. Oh, that’s right, I don’t need to run an antivirus on linux.

Panda Antivirus like NOD32 didn´t even let me save the file. Panda rocks!

AVG caught it. Whew!
March 17th, 2008 at 3:07 am
Avira too caught it!
I am using the premium edition, genuine version,
Got it from a free give away last month.
March 21st, 2008 at 3:35 am
AVG free didn’t catch it. Even right click, scan…no threats found. Time to try Nod32.
March 22nd, 2008 at 2:53 pm
Linux – the ultimate defense!
March 28th, 2008 at 4:36 am
Kaspersky caught just as I saved it…and then preceded to emit a loud screeching noise so I knew that a virus had been detected and deleted… I think I almost had a heart attack.
April 17th, 2008 at 11:33 pm

May 4th, 2008 at 12:04 am
