BO DLL Password Stealer

Posted: September 21, 2011

BO DLL Password Stealer is a spyware program that records keyboard input for the purpose of stealing private information, such as passwords and online bank account data. Although any BO DLL infection should be assumed to be active, unless you've taken measures to deactivate BO DLL, SpywareRemove.com malware researchers have noted that BO DLL may not show any significantly-visible symptoms on the computer. Minor issues with system performance, altered network or firewall settings and the presence of unusual files on your computer, may be all that's there to serve in the form of telltale signs of a BO DLL intrusion. Since BO DLL is difficult to detect or delete by manual methods, it's strongly recommended for you to use an anti-malware program to remove BO DLL from your PC.

BO DLL – Nestled Neatly Between Your PC and your Keyboard

BO DLL uses the standard spyware feature of keylogging, to steal the majority of the information that BO DLL targets. Similar types of spyware include Trojan-PSW.Gampass, Trojan-PSW.VBS.Half, Trojan-PSW.Lineage!rem and Trojan-PSW.Win32.Agent.soq, among other examples. The keylogging feature that's shared in common by BO DLL and BO DLL's other spyware friends is a passive monitoring tool that records all keystrokes from the keyboard into a small log file.

This log file is typically concealed in a Windows system directory. Although log files from BO DLL and other types of spyware are usually plain text, their names will try to obscure this so that they look like normal Windows components. Everything that you type is put into this log file, which is sent out by BO DLL to criminals who can peruse it for passwords and other information that can be used for fraud and account break-ins.

Detecting BO DLL by Its Internet Connectivity Requirements

Because BO DLL has to send BO DLL's log file out to a criminal in order to serve BO DLL's basic function, you may be able to detect and hamper a BO DLL infection by looking for network-related activity. Examples of BO DLL-related alterations of Windows can include the following:

  • Exceptions that have been added to your firewall. SpywareRemove.com malware experts note that you should never trust a program that adds itself to your firewall without requesting for your explicit permission beforehand.
  • Network ports that have been opened without your consent. Under normal circumstances, a certain range of network ports will be open by default. However, if you see a network port that was opened without your permission when BO DLL had previously been closed, you should be wary of infection by BO DLL and other forms of spyware and backdoor Trojans.
  • The presence of unusual system processes. You can view system processes in Task Manager, although advanced forms of spyware like BO DLL may attempt to hide themselves by infecting normal system processes.

If you find BO DLL on your PC, it's strongly recommended that you delete BO DLL with an anti-malware product. Afterwards, you may want to change all your account passwords, since this will prevent BO DLL's hackers from using their stolen information to break into your accounts.
