The Blizzard Launcher has detected the Backdoor.Bifrose.F Trojan on your machine which may be used to steal your World of Warcraft account name and password.
Trojans are a %26#8220;back door%26#8221; in to your machine which can allow hackers to obtain sensitive data as well as cause harm to your machine. Trojans differ from Viruses as Viruses replicate themselves and are designed to purely cause damage to the %26#8220;host%26#8221; machine. Each Trojan functions differently, however most are designed to obtain information through use of keyloggers or allow remote functions for the hacker to literally use your computer. Trojans pose a serious threat to all computer users and it is extremely important that they are removed immediately before information can be gathered. Some Trojans are also used to allow further infection, installing additional Trojan functions as well as Viruses.
Follow these steps to remove the Trojan and protect yourself from future infection:
1. Close the Blizzard Launcher. You are still allowed to log in and play, however playing the game with a Trojan installed puts your account at serious risk of being compromised as the hacker can easily obtain your World of Warcraft account name and password.
2. Ensure that all programs are closed. If you have recently downloaded any executable (.exe) files meant for use with the game, delete them so that they are not accidentally used in the future.
3. Use one or more of the below programs to help remove the Trojan and provide future protection against them. After installing the program, ensure that you update its %26#8220;definitions%26#8221;. Definitions are used as a dictionary of sorts for the program to help it detect new Trojans. This is usually prompted to be done shortly after install by the program itself. If not, the process to do so should be available within the program options.
4. Make sure you run a thorough scan of your entire system. After removing the Trojan, use the Blizzard Launcher again to start the game and see if any additional threats are detected.
Removal Programs
The below programs can all be used to detect and remove the Trojan found on your system. Programs with trial or free versions are marked as such.
