Detect, understand, and remove spyware to protect yourself

Spyware is a type of malware that is secretly installed on your device—without your knowledge or consent. It often disguises itself as a harmless program or hides within seemingly trustworthy downloads. Once active, it starts collecting sensitive information—such as passwords, email credentials or your search history—and transmits it to third parties.

The consequences can range from noticeably slower system performance to serious risks such as identity theft. Spyware is especially insidious because it often remains unnoticed for a long time. It can reach your device through infected files, email attachments or manipulated websites—and then operates secretly in the background.

There are several types of spyware. Here are the most common ones.

• Keyloggers records every keystroke a user makes. This allows cybercriminals to access passwords, credit card details, and personal messages.
• Adware Some variants bombard you with unwanted advertising. Clicking on a pop-up isn't just annoying—it can also be dangerous, as it may result in your personal data being shared without your knowledge.
• Infostealers These spyware types actively search your system for confidential data, including stored passwords, authentication details, and browser activity.

Since spyware is constantly evolving, compiling a complete list of all its variants is challenging. That's why it is especially important to stay alert and to check your system regularly for signs of infection.

 

If you suspect that your device is infected, there are several ways to remove spyware.

• Use anti-spyware programs: Specialized tools scan your system for suspicious files and reliably remove them. Many of these programs are available for free, while paid versions often offer advanced features.
• Consider manual removal: For advanced users, manual removal of spyware may be a viable option. However, this approach requires a solid level of technical expertise, as the malware is often deeply embedded within the system.
• Reinstall the operating system: If nothing else works, only one drastic step remains: completely reset your computer. Reinstalling the system will erase all data, so creating a backup beforehand is essential.

 

Prevention is ultimately the best protection. Implement the following measures to significantly reduce the risk.

• Update the operating system and the programs on a regular basis. Address security gaps at regular intervals.
• Install software only from trustworthy sources.
• Do not open suspicious email attachments or links.
• Use a reliable antivirus and anti-spyware program.
• Perform regular system scans, regardless of whether you observe any problems.

 

Spyware is one of the most common—and, at the same time, most insidious—threats in everyday digital life. It can spy on sensitive data unnoticed and cause significant damage. That is why it is crucial to recognize the typical signs, take appropriate protective measures and respond swiftly in the event of a breach. With vigilance and the right tools you can effectively protect yourself against this form of digital espionage.
