Imagine logging onto your computer and sensing that something isn’t quite right. It feels like your digital space has an unusual presence, but you can’t quite pinpoint it. If you find yourself in this situation or even suspect that something is off-point, there’s a real possibility that your computer has fallen victim to a Trojan virus.

According to Purplesec, a staggering 51.45 percent of all malware falls under Trojan viruses, and it’s not hard to see why. Trojans exhibit cunning traits that allow them to deceive and cause problems within your devices. Like their ancient namesake, the Trojan horse, they present themselves as innocent software, concealing their true malicious intent.

Trojan viruses are not to be taken lightly. They have the power to steal your most personal information, leaving you vulnerable to identity theft and other grave cybercrimes. This article will delve into Trojan viruses—their signs, steps to take when they infiltrate your system, and how to strengthen your computer security.

Signs of a Trojan Virus Infection

When it comes to Trojan viruses, early detection is critical to minimizing potential damage. By being aware of the signs that indicate your computer may be infected, you can take swift action to address the issue. Let’s explore some common red flags that might indicate the presence of a Trojan virus:

  1. Sluggish performance and frequent system crash: Sluggish performance and frequent system crashes are often tell-tale signs of a Trojan infection. If your computer suddenly becomes slow and unresponsive or crashes unexpectedly, consider the possibility of malware. These symptoms can indicate that malicious code is actively interfering with your system’s operations.
  2. Unexpected pop-up ads and redirects: Another sign to watch out for is the appearance of unexpected pop-up ads and frequent redirects while browsing the internet. If you notice an influx of intrusive ads or find yourself redirected to suspicious websites without your consent, it could be a sign that a Trojan has compromised your computer. These tactics are often employed by malware to generate illicit revenue or gather sensitive information.
  3. Unusual network activity: Be vigilant about unusual network activity on your computer. Suppose you notice excessive data usage or unexplained outgoing connections. In that case, it may indicate that a Trojan is communicating with its command-and-control server or engaging in malicious activities behind the scenes.

Paying attention to these warning signs can help you quickly recognize a potential Trojan virus infection and take appropriate measures to safeguard your system. In the next section, we will discuss the essential steps to take when dealing with a suspected Trojan infection, enabling you to regain control of your computer’s security.

Steps to Take When Your Computer is Infected

There are several places a Trojan virus can invade your computer. Before you begin searching for where the virus may be located, there are specific steps you have to take. First, start by disabling start-up programs on your computer that you don’t trust their sources and manufacturers. Rebooting your computer in safe mode is a great way to ensure that the virus can’t stop you from removing it. It is essential to know the nature of the specific programs you are removing so as not to remove the basic programs that make your computer function.

Below are other steps you can take when you suspect your computer is infected with a Trojan virus:

1. Use Microsoft Defender

Microsoft Defender is a reliable and free antimalware tool that comes with Windows, aiming to protect users from various threats, including viruses, malware, and spyware. To utilize Microsoft Defender and rid your computer system of the Trojan virus, follow these steps:

  1. Open the Windows search box by clicking the Start menu or pressing the Windows key.
  2. Type “Windows Security” and click on the “Virus & Threat Protection” option in the search results.
  3. Within the Windows Security app, locate the “Virus & Threat Protection” tab and click on it.
  4. Under the “Quick Scan” section, click on “Scan Options” to reveal additional scanning choices.
  5. Select “Full Scan” from the available options. This comprehensive scan thoroughly examines all files and areas on your computer.
  6. After selecting “Full Scan,” click “Scan Now” to initiate the scanning process.
  7. Microsoft Defender will now commence scanning your system for any potential Trojan viruses. It will meticulously analyze files, programs, and system areas.

If Microsoft Defender detects any Trojans during the scan, it will automatically take the necessary actions to remove them from your system, safeguarding your computer from their harmful effects.

2. Use System Restore

System Restore is a valuable feature on Microsoft Windows that allows you to revert your computer’s settings to a previous point, effectively addressing system malfunctions and problems.

If your PC is infected with a Trojan virus, using System Restore can be helpful. This feature restores your computer to a state before the Trojan appeared, bringing back previously uninfected files. However, it’s essential to note that System Restore only works if you have a restore point available from a time before the infection occurred.
Determining the availability of an appropriate restore point may not be easy. Consider the duration of your computer’s malfunction and try to recall when it was functioning correctly. Look for a restore point from before that period.

To begin the process, you need to check if your system has a previous System Restore:

  1. Type “Restore” in the Start menu search bar and select “Create a Restore Point.”
  2. In the System Properties window that appears, click on the “System Restore” button under the System Protection tab.
  3. In the subsequent System Restore window, select “Choose a different restore point” and click “Next” to select a specific restore point.

If you don’t have a previous restore point, there is an alternative that you can explore.

Assuming you have a suitable restore point, follow these steps:

  1. Choose a restore point where you think your system was functioning correctly, and click “Next.”
  2. Review the details of the restore point and ensure it aligns with your desired restoration. Then, click “Finish.”
  3. Your PC will restart, and the system settings will revert to the selected restore point.

Strengthening Computer Security

To prevent future infections and keep your computer safe, it’s essential to take proactive measures. Here are some simple and practical steps you can follow:

  1. Update your operating system and software regularly. Keeping your system up to date ensures you have the latest security patches and bug fixes. This helps protect against hackers.
  2. Enable automatic system updates whenever possible. With this, you won’t have to worry about constantly checking for updates. Automatic updates ensure that you stay protected with minimal effort on your part.
  3. Exercise caution while browsing the internet. Pay attention to the websites you visit and the links you click. Avoid clicking on suspicious or unfamiliar links, which may lead to malicious websites that can infect your computer. Use reputable browsers that provide built-in protection against phishing and malware.
  4. Educate yourself about social engineering techniques. Cybercriminals often use tricks and manipulative tactics to deceive unsuspecting users into downloading malicious files or sharing sensitive information. Stay vigilant and recognize common signs of social engineering, such as unsolicited emails or phone calls asking for personal information.
