Symptoms

• Dangerous Trojan generates pop-ups stating that your computer is infected with Trojans and providing links to free anti-malware programs, including Files Secure and IEDefender. These anti-malware programs are actually rogue anti-malware programs that will steal your financial information and download additional malware onto your computer. Moreover, Dangerous Trojan slows your computer, decreases your available memory, and may cause your system to crash or restart periodically.
  
  

Automatic Removal

• Dangerous Trojan can be removed automatically by running an up-to-date anti-malware program. Many of these programs are available for free online. In addition, Windows Defender, a free anti-malware program created by Microsoft, comes pre-installed with the Windows Vista and 7 operating systems. To access Windows Defender, click "Start," "All Programs" and "Windows Defender." Note that if for some reason Windows Defender cannot remove Dangerous Trojan, it will provide resources to help you remove the Trojan.
  
  

Manual Removal

• As an alternative to running an anti-malware program, you can remove the Dangerous Trojan manually. The benefit of removing the Trojan manually is that you don't have to be connected to the Internet or worry about whether your anti-malware program will detect and be able to remove the trojan. The downside to manual removal is that it is a technical process which, if done incorrectly, can cause significant system-wide failures. To remove the Dangerous Trojan manually, delete the following processes, registry values, and dynamic link libraries respectively.

Prevention

• To prevent the Dangerous Trojan from infecting your computer in the future, be sure to run an up-to-date anti-malware program at all times. Most anti-malware programs update themselves automatically by default, though others must be set to do so. In addition, run a firewall, avoid suspicious websites, and do not open email attachments from email addresses that you do not know or trust.
