Limites et contraintes du service VirusTotal

Limites de VirusTotal :
VirusTotal étant un service gratuit en ligne, il y a une limite à la taille des fichiers qui peuvent être envoyés à l'analyse : maximum de 64 MO. Donc il n'y a pas, dans la base de données de VirusTotal, de résultat d'analyse de fichiers de plus de 64 MO (un service de même nature, Metascan, a une limite à 80 MO).

• Nota :
  Les cybercriminels, sachant cette limite, écrivent des malveillances gonflées juste à plus 80 MO pour empêcher l'utilisation des redoutables services VirusTotal et Metascan.

Clé de l'API VirusTotal (VirusTotal API Key) :
Lorsque VirusTotal n'a pas encore analysé un contenu (il n'y a pas de résultat d'analyse dans sa base de données), VT Hash Check permet de lancer l'envoie (l'upload) du fichier à VirusTotal pour analyse. Cette fonction de VT Hash Check utilise une API de VirusTotal pour laquelle vous devez, préalablement, disposer d'une clé d'accès (gratuite). Pour obtenir cette clé, il suffit d'aller sur le site de VirusTotal et de rejoindre la communauté VirusTotal puis, sur leur site, de se connecter sous ce compte. Cliquez alors sur votre identifiant et une page s'ouvre affichant, entre autre, votre clé API (à conserver strictement confidentielle).

Limite anti-de DoS (Denial of Service) :
Vous ne pouvez pas lancer plus de 4 consultations de la base de données de VirusTotal à la minute. Cette limite peut être supprimée pour certains utilisateurs, sur demande à l'équipe VirusTotal.

If any provision of this Agreement is held to be unenforceable for any reason, such provision shall be reformed only to the extent necessary to make it enforceable and the remaining provisions of this Agreement shall not be affected.

If you have read this far then I commend you for your fortitude. You are entitled to one (1) free taco. Tacos may be claimed by walking up to me in a Taquería or other taco-serving establishment and requesting your free taco. Tacos have no cash value and may not be claimed except for in person as described above. You may request a burrito instead if you prefer burritos. Quesadillas are not an option. Ok, fine; you can have a quesadilla if you really want one. Or nachos.

Users who have need to use the software in a way which is not allowed under this license are encouraged to contact Boredom Software with their request.

If you have any questions concerning this license, you may contact Andrew Lambert.

1. Purpose

The purpose of this program is to quickly check the MD5 (or SHA1) checksum of a given file against the checksum database of VirusTotal.com. If the checksum matches a file already scanned by VirusTotal.com then the results of 41 anti-virus scanners are shown.

2. Installing

To install the program, run the setup.exe file.

3. Using

As of version 0.85, you will need an API key from Virus Total to use VT Hash Check. If you prefer to not get an API key, then you must use an earlier version of the program. Earlier versions are not supported and won't have any bugs fixed in them. An API key is free with a Virus Total Community account (which is also free.) Sign up at: http://www.virustotal.com/vt-community/register.html

VT Hash Check will ask you for your API key the first time you run it. Alternatively, you can specify an API key on the command line using the 'api=' argument followed by your 64 character API key.

To use the program, once installed, simply right-click on any file in Windows Explorer and choose "Check Hash" from the context menu.

Settings may be modified by running the vthash.exe program directly (i.e. without arguments.) You may toggle SHA1/MD5 and edit your API key. VT Hash Check can also be configured to automatically save all scan results to a directory. You may specify the directory and the save format in the settings window.

4. Uninstalling

To uninstall, either click "Remove" from the Add/Remove Programs control panel applet or execute the uninstall.exe file from the program's installation directory.

5. Bugs & Issues

None known ATM, but they're there.

6. Misc Notes

Virus Total is a free service provided by Hispasec Sistemas (http://www.hispasec.com/), independent IT Security laboratory. Boredom Software is not affiliated with them in any way nor have they provided input or are even (likely) aware of the development of this application. Hence, they should not be contacted with support questions. They cannot help youwith this application.

VirusTotal, and this program by extension, is not substitute any antivirus software installed in a PC, as it only checks individual files on demand. It does not offer permanent protection for the user's system either.

Although the detection rate afforded by the use of multiple antivirus engines is far superior to that offered by just one product, these results DO NOT guarantee the harmlessness of a file.

This program is in compliance with the terms and conditions set forth on the VirusTotal.com website as of the date of this writing. However, you, the user, should review the Terms and Conditions at http://www.virustotal.com/privacy.html before using this program.
