In this article we are going to put our emphasis on the so-called Trojan horses and their representative Dofoil Malware. Below we have provided all the necessary information for you to understand and deal with this threat successfully.
Trojans and their nature and sources. Dofoil Malware and its particular behaviour:
Generally speaking, the attacks caused by Trojan viruses represent one of the worst threats one can have the misfortune of coming across nowadays. All the Trojans are normally separated into two components – a server and a client. Usually – it is the client part that gets disguised as a seemingly safe software and put in peer-to-peer file sharing networks, or illegal download web pages. The most frequent means of infection is via email attachments. The creators of the virus normally use different spamming techniques with the purpose of spreading the virus to the unsuspecting users. Malware designers may even use chat software as a means of distributing their Trojan viruses (like Yahoo Messenger and Skype).
Trojans represent programs that seem harmless, however are, indeed, really malicious. Their name comes from the Ancient Greek mythology – the myth about the Trojan War. According to the legends, the Greeks created a huge wooden horse that the people of Troy allowed into the city, believing it was a present and a peace offer. However, at night, the Greek soldiers who had been hidden inside the horse went out and opened Troy’s gates to let their armies in and then crushed the city. Basically, that is what happens with your PC if you have been infected with a Trojan virus like Dofoil.

Dofoil works by lurking inside of what initially seems to be useful software programs. Nonetheless, as soon as it is executed or installed into the targeted system, this sort of virus may start affecting some files stored in the victim’s PC. Usually, any Trojan virus is also able to steal important data from the user’s system or the network it is connected to. As a result, the hackers who have sent this terrible malware will be able to gain the control over the computer using such a Trojan. While such horrible activities are taking place, the user may notice that the infected PC is now very slow or that some unknown windows appear without any activity from the affected users themselves. Following that, this could result in a computer crash.
However, unlike a standard viruses, malware programs like Dofoil cannot replicate. As the victim user is usually unaware that a Trojan horse has been installed, the computer’s security depends upon its anti-virus tool that would hopefully recognize the malicious code, and then could isolate it and remove it.
Uses of viruses such as Dofoil:
Actually, cyber terrorists have a long history of using Trojans as a means of tricking end-users into installing other types of malware into their systems. This is one of the Trojans’ most usual purposes. Normally, it is a Ransomware version that is distributed by viruses like Dofoil. Usually, as we have already discussed above, such a malicious program could be hidden within a seemingly harmless email attachment or a free software package, such as a pirated version of a popular game. As soon as the user gets the Trojan horse, the malware that is lurking inside would get loaded as well. We must say here that the popularity of Dofoil and of the other Trojan versions could be partly blamed on their incredibly multifunction nature. That means such a virus could be programmed to perform absolutely everything once installed on your PC.
Some of the other consequences resulting from the presence of any Trojan on your machine could be unwanted changes to your computer settings and various unauthorized activities even when the computer is supposed to be idle.
