Spotting the Trojan
Realizing you have a Trojan on your system can be difficult, especially if it isn’t showing any signs of slowing your PC down. Although currently using the Security Shield title, there is every chance that this software will appear at a later date under different titles – a common modus operandi for these fake security applications. (It’s a useful way to get around any web searches a clued-up potential user might conduct for reviews of the software before downloading it.)
Most Trojans will eventually make their presence felt, however, by applying reduced performance to your Windows computer in the shape of malware that eats up your system resources and possibly preventing access to the Internet. Bearing this in mind, you might wish to print out this page for reference later on.
Preventing access to the web is a clever trick used by the developers of malware to prevent you from finding help online. This is done via the HOSTS file, typically found in C:\Windows\System32\drivers\etc. With that folder open, right-click HOSTS and select Open, selecting Notepad as the program you want to use to open the file. If your system is infected, then the HOSTS file will be full of entries that will divert your browser to incorrect IP addresses - sometimes looping back to your PC - but usually sending you to another website that could potentially cause further frustration.
In the absence of effective security software on your PC (assuming you put all faith in Security Shield) you should be able to detect the presence of this Trojan by right-clicking the Windows taskbar and selecting Start Task Manager or simply tapping CTRL+SHIFT+ESC. Here you need to be looking for any apparently random strings of characters – this identifies the Security Shield process. Before proceeding, make a note of the random characters; if automatic removal fails you will require these to conduct a manual removal.
