Compare the output from
VALIDATE.EXE
and
PACKING.LST
.
The sizes, creation dates and times, and validation codes for each file name must
match
exactly.
If they do not, delete the file immediately. Do not open the file or
examine it with any other utility; this may cause virus infection.
Checking your installation with
VALIDATE.EXE
does not guarantee that your copy is free
from defects, copying errors, virus infections or tampering, but the program’s security
features make it extremely unlikely that anyone has tampered with files that have
correct validation codes.
Testing your installation
After it is installed, the program is ready to scan your computer for infected files. You
can run a test to determine that the program is installed correctly and can properly scan
for viruses. The test was developed by the European Institute of Computer Anti-virus
Research (EICAR), a coalition of anti-virus vendors, as a method of testing any anti-virus
software installation.
To test your installation:
1
Open a standard MS-DOS or Windows text editor, then type the following character
string as
one line, with no spaces or line breaks:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
2
Save the file with the name EICAR.COM. The file size will be 68 or 70 bytes.
3
Start your scanning software and allow it to scan the directory that contains
EICAR.COM. When the software examines this file, it reports
Found EICAR test
file NOT a virus.
Caution
The line shown above should appear as
one line
in your text editor window, so be sure
to maximize your text editor window and delete any line breaks. Also, be sure to type
the letter O, not the number 0, in the “X5O...” that begins the test message.
If you are reading this manual on your computer, you can copy the line directly from the
Acrobat PDF file and paste it into Notepad. You can also copy this text string directly
from the “Testing your installation” section of the README.TXT file, which is in your
scanner’s program directory. If you copy the line from either of these sources, be sure
to delete any carriage returns or spaces.
Caution
This file is
not a virus —
it cannot spread or infect other files, or otherwise harm your
computer. Delete the file when you have finished testing your installation to avoid
alarming other users. Please note that products that operate through a graphical user
interface do
not
return this same EICAR identification message.
