EICAR- European Institute For Computer Antivirus Research, Chinese called the “Association of European anti-computer virus.” Aim is to increase the depth of anti-virus research development and promotion of antivirus software.

The EICAR test file is used to test the degree of anti-virus software accordingly. This file allows people without the use of computer viruses to test their anti-virus software. In some time ago, some anti-virus software developers began EICAR test file will be added to your package. Although it is not a virus, but anti-virus software to put it to test for the virus. Such a “virus” test is to satisfy those who have not met in real life, but want to see how the virus anti-virus software to detect viruses user response, such as it is to inform the user what way, there will be what kind of tips, etc. .

EIAR test file size is only 68 or 70 bytes of text files. .com File is legitimate executable files. It can run under Microsoft Windows operating systems and similar systems (due to limitations hexadecimal, 64-bit systems can not run) environment. It is not a virus. When the command is executed, it displays only the text message “EICAR-STANDARD-ANTIVIRUS-TEST-FILE”, then terminates, control is returned to the operating system. So a lot of antivirus software to detect it as “EICAR-Test-File”

EICAR test character says:
