There is a whole number of annoying little parasites that can make your day into the worst nightmare. Trojan.KillProc is one of these computer threats. This program is a Trojan which means that it can enter your system under the pretense of being a useful application. In fact, it is possible that you have downloaded Trojan.KillProc on your own, because this parasite can come paired up with various shareware programs. It is a sneaky pest, because it installs itself without your knowledge or consent, and then performs certain changes in the Windows Registry, that allows Trojan.KillProc to load automatically whenever you boot your Windows.

As a result, Trojan.KillProc runs in the system background and injects codes into genuine Windows processes. For example, wuauclt.exe process that you can find running in Windows Task Manager originally is Windows Update AutoUpdate Client. It connects to the Microsoft website looking for updates for your operating system. The original wuauclt.exe file is located at C:\Windows\System32 directly. However, if the wuauclt.exe running in your Windows Task Manager is located somewhere else, then it is definitely a part of Trojan.KillProc.

There are many versions of Trojan.KillProc and the first one was discovered way back in 2005. The main thing that this Trojan does is disabled your computer security programs. For example, it can kill the Windows Security notifications, allowing various infections to spread in your system undetected. Thus Trojan.KillProc basically prepares your computer for other infections, and makes it vulnerable. So if you notice that your computer is acting strange and slower than usual, be sure to perform a full system scan with a reliable security product. You might find Trojan.KillProc damaging your system, and once you do, remove Trojan.KillProce immediately. You can use the said security product to remove the Trojan automatically, or follow the instructions and terminate it manually, if you have enough knowledge how to do that.
