- Dell Inspiron 2600 computer
- Pentium 1.13 GHz Celeron CPU
- 256mb RAM
- 30gb HDD
- Fresh installation of Windows XP (Dell OEM)
- Approximately 12gb of hard disk space occupied on the
test-bed computer, consisting of:
- Operating system installation
- Microsoft Office XP installation
- Varying small and large Microsoft Office documents
(Word, Excel, Powerpoint, Access)
- Varying small and large image files (JPEG’s
from a digital camera)
- Varying small and large files of other types (archives,
mpegs, text files, etc)
- The end result is a large quantity and vast variety of
different file types ranging in size
from a few bytes to 1.5 gigabytes.
- The performance tests were conducted by a 4D Digital Security
- The entire benchmark process was supervised and performed
in the presence of an independent
- auditor from the international audit firm group BDO
- The results of the process were verified by BDO
Test 1: “On-demand” C: drive scan
- The software being tested performs a full manual scan
of the C: drive, and the length of
time taken is recorded.
- Test 1 was broken down into 1a and 1b. Test 1a was performed
with the software’s default
settings, and Test 1b is performed with “maximum”
settings, which attempt to force the
software to scan all file types, extensions, archives, etc.
- This test serves to provide an indication as to the speed
and efficiency of the antivirus
software program’s scanning engine while handling
large quantities of varying data.
Test 2: “On-Access” speed degradation
- This test serves to measure to what degree the resident
“on-access” scanner of the tested
software degrades the performance of the test-bed computer
during the opening/closing of
a Microsoft Office file.
- A 183kb Excel spreadsheet, replicated 200 times across
2 folders was opened and closed
using an Excel macro as fast as possible, and the time taken
to open and close all 200 files
- This test was performed initially without any antivirus
resident scanner installed, in order to
ascertain a benchmark figure for the speed of the computer
without any antivirus program
present, and then with each subsequent resident scanner
installed and active.
- This test shows to what degree the different resident
scanners slow down the daily use
of a computer and degrade it’s performance, compared
to when no antivirus is employed.
