If you’ve noticed that your computer has started acting a bit unusual, then you might have an unwelcome guest — a Trojan horse, specifically the Spyboy variant, nestled somewhere in your system. Before we move to the next paragraphs in this guide, where we will explain how to remove this malware, we need to make it clear that Trojan horses like Spyboy are like the Houdini of cyber threats — they’re masters of digital deception, often leaving no clear signs of their destructive activities. Therefore, to successfully deal with them, you’ll need more than a regular antivirus software to spot these culprits because they tend to leave no digital fingerprints.

What is Spyboy?

Now, that we’ve scratched the surface, you’re probably wondering what exactly Spyboy is and how it operates, right? Well, think back to the ancient tale of the Trojan War and the cunning strategy employed by the Greeks with the wooden horse. In our modern-day cyber universe, Spyboy functions in a similar deceptive manner. It disguises itself as an innocuous and appealing software, game, or enticing link, luring unsuspecting users into its trap. Once it infiltrates your system, the malware initiates its harmful routines, causing chaos and potential damage. This malicious program may bombard you with intrusive advertisements, track your online activities without consent, steal your sensitive information, or insert ransomware to encrypt your valuable files and hold them hostage until a ransom is paid.

Is Spyboy a Virus?

So, does this mean Spyboy is a virus? Actually, no. While viruses and Trojans share a common goal of causing harm, their methods of operation differ. Viruses spread by infecting legitimate files and replicating themselves, much like a contagious flu virus spreading from person to person. In contrast, Spyboy or Zamguard64.sys, being a Trojan, adopts a more deceptive approach. It tricks users into willingly downloading and installing it, often disguised as something harmless or enticing. It’s like a cyber con artist, deceiving its victims into letting it into their system. Once inside, the Trojan can carry out a range of malicious activities, such as stealing sensitive information, spying on your online activities, or creating a backdoor for other malware to enter.

Spyboy Virus

Although often referred to as the Spyboy virus, it’s important to clarify that Spyboy is actually a Trojan, with a very diverse skill set. Once inside, the malware has the ability to monitor your online activities, capture sensitive information such as passwords and financial data, and even manipulate or corrupt important files, leading to data loss or system instability. Additionally, it can turn your device into a puppet under the control of remote attackers, utilizing it as a launchpad for coordinated cyberattacks on other systems or networks. Furthermore, the threat often acts as a gateway, welcoming other malicious software into your system, further expanding the potential damage and compromising your cybersecurity. So, don’t let the term “Spyboy Virus” fool you because this threat can turn your digital life upside down.

Spyboy Trojan

What makes Spyboy trojan genuinely spine-chilling is its ability to remain incognito. This threat is the cyber equivalent of a covert spy. It can infiltrate your system, lie low for years, and secretly cause damage. It’s highly skilled at camouflaging itself as regular files or even disabling your antivirus without you even noticing. And, as we already explained, the dangers posed by Spyboy trojan are not to be taken lightly. Therefore, to stay safe, it’s crucial to remain vigilant and implement robust security measures to detect, remove, and protect against the multifaceted threats posed by the Trojan. Regular system scans, strong firewalls, up-to-date security software, and safe browsing practices can go a long way in safeguarding your digital ecosystem from this insidious malware.

Step1 Uninstall the Spyboy app and kill its processes

The first thing you must try to do is look for any sketchy installs on your computer and uninstall anything you think may come from Spyboy. After that, you’ll also need to get rid of any processes that may be related to the unwanted app by searching for them in the Task Manager.

Note that sometimes an app, especially a rogue one, may ask you to install something else or keep some of its data (such as settings files) on your PC – never agree to that when trying to delete a potentially rogue software. You need to make sure that everything is removed from your PC to get rid of the malware. Also, if you aren’t allowed to go through with the uninstallation, proceed with the guide, and try again after you’ve completed everything else.

  • Uninstalling the rogue app
  • Killing any rogue processes

Type Apps & Features in the Start Menu, open the first result, sort the list of apps by date, and look for suspicious recently installed entries.

Click on anything you think could be linked to Spyboy, then select uninstall, and follow the prompts to delete the app.

Press Ctrl + Shift + Esc, click More Details (if it’s not already clicked), and look for suspicious entries that may be linked to Spyboy.

    Delete Spyboy files and quit its processes.

    After that, if the rogue process is still visible in the Task Manager, right-click it again and select End Process.

    Step2 Undo Spyboy changes made to different system settings

    It’s possible that Spyboy has affected various parts of your system, making changes to their settings. This can enable the malware to stay on the computer or automatically reinstall itself after you’ve seemingly deleted it. Therefore, you need to check the following elements by going to the Start Menu, searching for specific system elements that may have been affected, and pressing Enter to open them and see if anything has been changed there without your approval. Then you must undo any unwanted changes made to these settings in the way shown below:

    • DNS
    • Hosts
    • Startup
    • Task
    • Services
    • Registry

    Type in Start Menu: View network connections

    Right-click on your primary network, go to Properties, and do this:

    Undo DNS changes made by Spyboy

    Type in Start Menu: C:\Windows\System32\drivers\etc\hosts

    Delete Spyboy IPs from Hosts

    Type in the Start Menu: Startup apps

    Disable Spyboy startup apps

    Type in the Start Menu: Task Scheduler

    Delete Spyboy scheduled tasks

    Type in the Start Menu: Services

    Disable Spyboy services

    Type in the Start Menu: Registry Editor

    Press Ctrl + F to open the search window

    Clear the Registry from Spyboy items
