Infostealer.Dunfyter
What is Infostealer.Dunfyter?
Infostealer.Dunfyter Trojan only affects those who play the online game Dungeon & Fighter (DNF). The Trojan attempts to steal information from online users playing the game. Though the risk is low and only targeted to a small audience, it’s important to be aware of this threat.
How to remove Infostealer.Dunfyter?
- Disable System Restore (Windows Me/XP).
Disabling system restore is important before proceeding to delete the virus because if system restore is turned on then the computer will store a back-up of the virus also and all the efforts would be wasted.
- Update the virus definitions.
Virus definition update can be carried out using the live update feature which is present in all major antivirus software. Just click on the ‘Live Update ‘link and then proceed according to the instructions given.
- Run a full system scan.
Post updating of virus definitions, run a full system scan and be sure to scan the sub folders also.
Precautionary Measures
- ♦ Use a firewall to block all incoming connections from the Internet to services that should not be publicly available.
- ♦ Enforce a password policy. This helps to prevent or limit damage when a computer is compromised.
- ♦ Use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application.
- ♦ Disable AutoPlay to prevent the automatic launching of executable files on network and removable drives.
- ♦ Turn off file sharing if not needed. Grant access only to user accounts with strong passwords to folders that must be shared.
- ♦ Turn off and remove unnecessary services.
- ♦ Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
- ♦ Configure your email server to block or remove email that contains file attachments that are commonly used to spread threats, such as .vbs, .bat, .exe, .pif and .scr files.
- ♦ Isolate compromised computers quickly to prevent threats from spreading further.
- ♦ Do not execute software that is downloaded from the Internet unless it has been scanned for viruses.
- ♦ Turn off Bluetooth or set it to ‘Hidden’ mode. If device pairing must be used, ensure that all devices are set to "Unauthorized", requiring authorization for each connection request. Do not accept applications that are unsigned or sent from unknown sources.
