Certains logiciels antivirus afficheront des avertissements de programme malveillant ou de vulnérabilité lors du démarrage du Navigateur Tor. If you downloaded Tor Browser from our main website or used GetTor, and verified it, these are false positives and you have nothing to worry about. Certains antivirus considèrent que les fichiers qui n’ont pas été vus par un grand nombre d’utilisateurs sont suspects. To make sure that the Tor program you download is the one we have created and has not been modified by some attacker, you can verify Tor Browser's signature. You may also want to permit certain processes to prevent antiviruses from blocking access to Tor Browser.
