TrojanDownloader:MSIL/Demibot.A

The clandestine TrojanDownloader:MSIL/Demibot.A is a malicious spyware dropper which uses a number of cloaked files, meaning that malignant files copy the names of authentic Windows components or the real files are modified to serve the infection. This is a highly malicious trick which not only allows schemers to drop tens of seemingly reliable files but also helps hide the malicious Trojan from discovery and removal. Needless to say, it is a must to delete TrojanDownloader:MSIL/Demibot.A, primarily because the devious threat can perform private data and identity theft. Schemers could use your name to spread malware to other operating systems and even lead you to financial loss. As you may suspect the removal of the infection is not easy or straightforward.

It seems that Windows users struggle with the detection of TrojanDownloader:MSIL/Demibot.A. Of course, it may be difficult to find a malicious program which does not have an interface. Nonetheless, you should identify certain symptoms and dysfunctions which belong to a Trojan. First of all, Trojans like this one use tens of different components which take over CPU memory and considerably slow down the entire system. Additionally, you may find existing security tools disabled or even removed and the settings of different web browsers modified. Also be aware of new folders and links on the Desktop or Start menu. And who should you blame for this activity.

As mentioned before, it may be difficult to remove TrojanDownloader:MSIL/Demibot.A files because they use the names of legitimate components. For example, winlogon.exe is an important Windows element which is responsible for authorization and activation processes within the system. Unfortunately, a malignant file with the same name can download spyware, employ BHO to spy on your virtual habits, record usernames and passwords, hijack personal IM or email accounts, send mass spam email accounts and release a number of fictitious security pop-ups. This file may aid amsecure.exe, a rootkit component which is often seen running alongside a fake AV tool Internet Security 2013.

You may also need to remove AdobeUpdater.exe, kdhr.exe, setup.exe, Boonty.exe (69.12K), Defrag.exe and Explorer.exe. This authentic component found under %WINDOWS% is responsible for the activity of the file manager, desktop, taskbar and similar Windows utilities. Unfortunately, it is a must to delete the TrojanDownloader:MSIL/Demibot.A version of this executable because it can disable safe mode, remove access to Task Manager and Registry Editor and corrupt the File Protection system in order to aggravate manual removal tasks. The file is also known to steal private data, release fake pop-ups and corrupt the USB drives, which could be used to spread malware further.

It is exceptionally difficult to delete TrojanDownloader:MSIL/Demibot.A manually because of the activity of the aforementioned files and such rootkits as nbt.exe and amsecure.exe. Only highly experienced computer users will be able to find and remove all of the malignant Trojan’s components. If you do not think you have reached the expert user level yet – install automatic spyware removal software. We recommend using the legal, reliable tool SpyHunter.
