Note: Spycar is a suite of tools (about 25 small programs) designed to test the behavior-based defenses of an anti-spyware tool...mimic malware-like behavior in a benign form. Each program engages in some type of behavior normally associated with malware...it will add favorites to Internet Explorer or add a file and change the registry so that the file is launched at start-up. After testing is complete, the software will undo all of the changes it made.
Note: The EICAR test file is not malware, nor was it created by malware authors. The EICAR test file was created by Eddy Willems, a board member of EICAR (European Institute for Computer Anti-Virus Research)/
* VT results for strict interpretation (68 bytes)
* VT results for whitespace interpretation (70 bytes: 68 bytes + CR NL)
You can also create your own Eicar test file by opening Notepad (or other text editor), copy and paste the following string of characters in the code box below into a new text file, and then saving it.
Your anti-virus program should promptly detect the file as an actual virus, alert you and remove it.
Eicar: Anti-Malware Testfile
Using real viruses for testing in the real world is rather like setting fire to the dustbin in your office to see whether the smoke detector is working. Such a test will give meaningful results, but with unappealing, unacceptable risks.
Before anything a general warning, never try to test/try out malware samples if you don't know what you're doing! The risk of inadvertently infecting another computer or a host computer is always present.
...testing malware samples with different security products is not very productive in my opinion. You would indeed need a site that is actively dropping the infection (which is hard to find, they are usually cleaned/taken off-line as soon as the malicious behavior is observed and reported). Downloading and dropping specific files isn't the same and doesn't give a good representation of how a "real" infection enters a system.
