How to Check to See If Someone Is Spying on Your Computer

by Melissa King

Your computer houses personal, private information, such as passwords, emails and financial data. An anti-spyware program protects your computer from most spies and data thieves. These programs, while capable of detecting many intrusions, cannot find every piece of spyware on your computer. Employers or spouses sometimes install spyware or keyloggers on your computer to track your whereabouts or see your actions online. Spies that are more malicious use keyloggers to steal credit card numbers or your bank account information. Spyware usually operates silently, so finding it is often a challenge.

1

Download and install an anti-spyware program, such as Avira, Ad-Aware or SuperAntiSpyware. Some programs offer free trial versions. An anti-spyware program roots out most spyware and prevents further infections.

2

Install a keylogger detector, such as Malware Defender, Max Spyware Detector or KL-Detector. These programs find keyloggers installed on your machine. Some quarantine or remove them for you.

3

Listen to the things people tell you in your conversations. If the person seems to know information you typed in an email but have never said aloud in public, that person may have installed a keylogger on your computer.

4

Enter your password to log in to your online bank, email or social networking accounts. If you cannot log in, your password may have been changed by someone spying on the computer.

5

Look at your online profiles and other public information. If your profiles or posts contain information you didn't enter, this usually indicates a computer spy.

Tip

  • check Use strong passwords, containing a combination of letters, numbers and special characters. This prevents people from guessing your password.

Warning

  • close If you work in a public office, never use your work computer for personal reasons. Some employers monitor their employees' computer behavior.
