The computer, just like living organisms, is subjected to diseases. These infections, just like in living things, are being contacted and they spread across the whole computer. Infections that attack the computer usually enter in different ways or means. These infections are commonly known as Malware, which means malicious software. Any harmful program created to harm or exploit computer systems, networks, or users is referred to as malware.
A specific kind of malware called a virus spreads itself by infecting other files or computer systems. Being the general name, malware has many examples like viruses, Spyware, ransomware, and more. The computer virus, being a type of malware enters the computer in different ways, especially via files from unknown or dubious sources.
These files could be sent from emails, or even you get to download them from websites. Without being told, they have adverse effects. Viruses, also have different types based on how they get into the computer. Their types include the Trojan virus, macro virus, worms, etc. One of the most dangerous and common ones is the Trojan virus, but overall, it is still preventable or solvable. Now, let’s look at what it is, and how to get rid of it.
What is the Trojan Virus?
A trojan virus, or simply a trojan, is a form of harmful software that impersonates other, trustworthy programs. It gets its name from the myth of the Trojan Horse, in which Greek warriors sneaked into Troy disguised as a wooden horse. Similarly, to this, a trojan virus entices users to download or use it by seeming to be legitimate software or files.
The trojan, however, can carry out several dangerous tasks without the user’s knowledge once it has been installed or activated, such as stealing confidential data, getting unauthorized access to the machine, or acting as a backdoor for other malware.
In contrast to viruses, trojans rely on user interaction to spread instead of self-replicating. They could seriously harm the computer because they are so harmful. A virus that can remotely allow Unauthorized Access to the computer, is made to steal sensitive or private data, and can even cause system instability and crashes. This virus mostly targets businesses, sectors, and individuals who have sensitive data on their computer or server systems.
How does the Trojan Virus get into the Computer system?
Just like the history behind the Trojan horse, this virus type is disguised as good and favorable software, but we know the rest of the story.
That being said, they can get into the computer system in many ways. Ways that include via email attachments, social engineering, infected websites, software vulnerability, and software downloads.
Trojan viruses are frequently distributed via email attachments. Attackers frequently use things that appear innocent, including documents, photos, or executable files, to conceal trojans. The trojans are activated when users open or download these attachments, giving them access to the computer system.
When handling email attachments, especially those from unknown or dubious sources, it’s crucial to use caution. Unexpected emails containing attachments should be avoided until you can confirm their legitimacy. Be cautious when opening them.

Another method for spreading Trojan infections is social engineering. Attackers utilize psychological tricks to trick users into taking activities that unwittingly download malware into their systems. This may entail employing strategies like phishing emails, false websites, or phony phone calls that impersonate reputable people or organizations.
Attackers deceive users into downloading dangerous files or divulging sensitive information by capitalizing on their trust, curiosity, or fear. It’s critical to be watchful and dubious about demands for personal or confidential information that are not requested.
Trojan virus dissemination is significantly aided by software flaws. These vulnerabilities are holes or weak points in software that an attacker could use to get access without authorization or run harmful code. Trojans frequently target well-known flaws in plugins, apps, or operating systems.
Once a weakness has been found, attackers can create Trojans that are particularly made to take advantage of it. Software must always be updated with the most recent security patches because these frequently fix known vulnerabilities. This is why regular installation of the apps and operating systems is advised, as they come with security measures and bug fixing for virus loopholes.
These websites may include hacked or malicious code that surreptitiously infects users’ systems. Drive-by downloads are a method for distributing Trojans, whereby merely visiting a hacked website can cause the Trojan to be downloaded and installed without the user’s knowledge or agreement. Through phishing emails, malicious advertising, or compromised links, users may be led to infected websites.
Software and Drive-by download
Trojan viruses are frequently distributed using software and drive-by downloads. To insert harmful code into trustworthy files or webpages, attackers make use of flaws in software, operating systems, or web browsers. The Trojan is stealthily installed on users’ computers when they unknowingly download and install infected software or browse websites that have been compromised. Drive-by downloads take place when a user doesn’t have to do anything for malware, such as Trojans, to automatically download and install itself when they visit a website.
What typical symptoms of a Trojan virus infection are there?
The presence of strange files or programs on the computer, as well as slow system performance, frequent crashes, unexpected system behavior, unauthorized access to files or accounts, and excessive network activity, are all warning signs of a Trojan virus infection.
Steps you should take when your computer has a trojan virus infection
- Disconnect from the internet or turn off Wi-Fi to stop the Trojan from interacting with other devices or spreading.
- By pressing a certain key (such as F8 or Shift) during boot-up, you can put your computer into safe mode and reduce the Trojan’s capacity to function.
- Thoroughly scan your entire system and eliminate any risks found by using reliable antivirus or anti-malware software.
- Check your computer manually for any suspicious files or Trojan-related software. Delete these suspicious files to get rid of the infestation completely.
- To re-infect your computer, some Trojans can conceal themselves in system restore points. Verify your system restore preferences and remove any restore points that the infection produced.
- Change the passwords for critical accounts like email, banking, and social media to avoid illegal access.
- Keep a watchful eye on your financial and personal accounts and notify financial institutions of any unlawful activity.
- Install the most recent updates and patches to keep your operating system and software up to date.
- If you’re unsure of the extent of the infection or unable to get rid of it on your own, think considering getting help from a reputable computer repair shop or your antivirus program’s support staff.
