EICAR and GTUBE Generator

Hi Folks,
today I wanna share a little but interesting (at least to me) mini software for testing ANTI-VIRUS and ANTI-SPAM engines.I called it EICAR-GTUBE-Creator and it's a little utility to create run time EICAR Test Antivirus file and GTUBE anti spam test mail.

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.


The GTUBE (Generic Test for Unsolicited Bulk Email) is a 68-byte test string used to test anti-spam solutions, notably those based on SpamAssassin. In SpamAssassin, it carries an antispam score of 1000 by default, which would be sufficient to trigger any installation.


The EICAR Anti-Virus test file is great to test your Anti-Virus software, but it’s not easy to handle, because your Anti-Virus software keeps deleting it. For this reason I came out with this utility. Here the main window, by clicking on EICAR button the utility will generate the the EICAR file in the current directory. Your AV should detect it immediately ! This utility can be used also to measure AV performance in detecting this file.

Here the GTUBE window. Basically you have to send one email to the testing email box. The utility will automatically add the GTUBE "Infection".



Finally the Source code and the executable (JAR, platform independent).

Java (platform independent) executable (jar)

Enjoy your testing

I'm the kind of hombre who enjoys to taste new stuff. Currently I am manufacturing my own pv panels. I'm managing it all alone without the help of my staff. I am utilizing the net as the only path to acheive that. I saw a truly amazing site that explains how to make photovoltaic panels and wind generators. The web site explains all the steps involved in solar panel construction.

I'm not sure about how precise the data given there is. If some experts over here who have experience with these works can have a see and give your feedback in the thread it will be great and I would extremely treasure it, cauze I really love solar panel construction.

Tnx for reading this. You guys rock.
