2-12 October 2003
 
 
    *
      The test was made on 02-12 October 2003, using Windows 2000 SP4 on a CELERON 1100 Mhz, 384MB SDRAM.
    *
      All programs tested had the latest versions, upgrades and updates and they were tested using their full scanning capabilities e.g. heuristics, full scan etc.
    *
      The 58306 virus samples were chosen using VS2000 according to Kaspersky, F-Prot, RAV, Nod32, Dr.Web and McAfee antivirus programs. Each virus sample was unique by virus name, meaning that AT LEAST 1 antivirus program detected it as a new virus.
    *
      ALL virus samples were unpacked and the only samples that were kept were the ones that were packed using external-dos-packers (that means not winzip, winrar, winace etc).
    *
      The virus samples had the correct file extension using a special program (Renexts) and were unique, according to checksum32 filesize.
    *
      All "fake" virus samples were removed, as well as "garbage" files.
    *
      The program PER was not tested because there was no english demo version available.
    *
      The programs BOClean , VET and Freedom were not tested because there was no demo version available.
    * The program InVircible did not include a "typical" scanner-function and could not be tested.
    *
      The programs MR2S and VirusNet are no longer supported.
    *
      The program V-Catch checks only mail accounts and could not be tested.
    *
      The programs AVK and MKS_VIR did not have an english demo version available. Because of this, both antivirus companies provided us with an EXCLUSIVE beta english version, for their use in this test. For this, we would like to express our gratitude.
 
    The following file types were used.
 
    ANS, ASM, BAT, ???, CHM, CLA, CLS, COM, CSC, DAT, DOC, ELF, EXE, HLP, HTM, INI, JS, MDB, MSG, PHP, PIF, PL, PPT, REG, SCR, SH, SHS, SMM, SYS, TD0, TPU, VBS, WBT, XLS, XML.
 
    The virus samples were divided into these categories, according to the type of the virus :  
 
    *
      File = BeOS, FreeBSD, Linux, Palm, OS2, Unix, BinaryImage, BAS viruses.
    *
      MS-DOS = MS-DOS and HLL*. viruses.
    *
      Windows = Win.*.* viruses.
    *
      Macro = Macro and Formula viruses.
    *
      Malware = DoS, Constructors, Exploit, Flooders, Hoax, Jokes, Nukers, Sniffers, Spoofers, Virus Construction Tools, Virus Tools, Corrupted, Droppers, Intended, PolyEngines.
    *
      Script = BAT, Corel, HTML, Java, Scripts, VBS, WBS, Worms, PHP, Perl viruses.
    *
      Trojans-Backdoors = Trojan and Backdoor viruses.

Et enfin tenir compte de la lourdeur d'utilisation :
Kaspersky est très bon mais bouffe des ressources.
Avast4 parmi les gratuits est sans doute le plus intéressant. module résident, messagerie y compris Mozilla ce qui n'est pas le cas de tous (kaspersky par ex.), messagerie instantanée, peer...
