Trojan.Namsal

Posted: March 4, 2011

Trojan.Namsal is a backdoor Trojan – in addition to being able to place other malware threats on your computer Trojan.Namsal can also attack your system security. Remote attackers use backdoor Trojans like Trojan.Namsal to control distant systems and may steal information or use the computer for malicious acts. The importance of deleting Trojan.Namsal can't be overstated since all of Trojan.Namsal's functions are highly likely to result in the theft of personal information or lasting damage to the invaded computer.

Let Trojan.Namsal in Through the Front and Trojan.Namsal Will Stab You in the Back

Trojan.Namsal has a large repertoire of potential attacks in store for any computer, as you can see here:

  • You may find important security functions, such as anti-virus applications, Task Manager or Windows Update completely disabled. This keeps you from responding appropriately to confirmed malware threats or detecting new possible threats, and gives Trojan.Namsal free reign to do what it wants.
  • Trojan.Namsal may also block your browser from viewing security-oriented websites. This is usually accomplished through proxy server-based hijacking tricks and can also be exploited to redirect you to malicious URLs.
  • Some sources report that Trojan.Namsal can use networks as a path to fresh computers. Keep on your guard when interacting with network-shared files, and be particularly careful on a machine that's part of a large network.
  • Your firewall is very likely to be violated by Trojan.Namsal to allow Trojan.Namsal to accomplish other functions. Security holes in your firewall can allow inbound traffic, such as new files dropped on your system, or outbound traffic like the unauthorized transmission of personal information.
  • Trojan.Namsal is nearly certain to download and install other malware programs onto your system. Some sources report that Trojan.Namsal concentrates on spyware-based drops that can easily record and steal sensitive data.
  • Remote attackers often use Trojans like Trojan.Namsal to take over computers for Denial-of-service attacks. DDoS attacks are one of the most well-known possibilities, but remote attackers may also take a wide range of other malicious actions.

Spring Cleaning Trojan.Namsal from Your Machine

Once you're ready to delete Trojan.Namsal, be prepared to stop Trojan.Namsal and all other malware from running before you do anything else. Trying to remove Trojan.Namsal and related infections while any malware is still active is a quick and easy recipe for failure. Rebooting into Safe Mode by tapping F8 during the boot process will often let you stop malware from starting, provided they lack rootkit functions.

Since the risk of other infections being present is high, you should scan your entire computer with good anti-virus applications and not just stop at removing Trojan.Namsal. Your computer will be secured again only if you've taken care of all related infections and not just their 'door man' Trojan.Namsal.
