What does a Trojan horse look like?

Do you know that nearly 75% of all the malicious infections that happen through the internet are caused by Trojan horses? Yes, this is quite a big percentage, which kind of gives an idea of how widespread, how popular and how common these nasty infections are. A major role in their success is played by the fact that Trojans can camouflage and it is very difficult to tell exactly what such malware looks like. Sometimes, it may come in the form of a harmless-looking file, an attachment, an ad or a link, while in other cases, it may be delivered to your email inbox in the form of a spam message. On a daily basis, hundreds of Trojan threats are released by anonymous cyber criminals that program them to perform various harmful activities. Different types of fraud and theft are just some of the most common things one may experience if they have a piece like Trojan.Multi.DNSChanger.a on their system. However, there could be many more possible usages. Let us give you an idea in the next paragraph.

What may a Trojan like Trojan.Multi.DNSChanger.a Virus do?

Spread other viruses: If a Trojan horse has managed to get inside your system, you should know that many other nasty malicious threats may sneak inside as well. Basically, the Trojan acts as a backdoor for Ransomware, Spyware and other dreadful viruses and can help them invade your PC in a very stealthy way.

Spy on your individual or professional life: In some cases, the Trojan infection could be effectively exploited as a tool of stalking and spying. With its help, the hackers can gain full access to your system, steal files or other sensitive information such as passwords, login credentials, personal identification information, confidential work details, bank account details, etc. We don’t need to tell you that with such type of data in their hands, they can perform various types of crimes – from money theft, identity theft, business secrets theft to even real blackmail and mental and physical abuse.

How do Trojans spread and how to avoid them?

Trojans are far trickier than most of the typical viruses. They may use plenty of malicious transmitters to delude the web users and get easily inside their system. Their ability to camouflage has made them almost indistinguishable from the usual web content that the people normally interact with.

Basically, without proper antivirus program, it may not be possible to recognize and avoid the infection, that’s why we strongly advise you to invest in reputed security software and ensure your PC is regularly scanned with it. Also, update your OS to the latest security patches and don’t keep outdated programs, the vulnerabilities of which may be exploited by a sophisticated infection like Trojan.Multi.DNSChanger.a.
