How to Know Your Computer Has Been Hacked

Determine if any unauthorized use of resources has occurred on your computer.

When a hacker gets into your computer, he needs to access the computer's resources by logging in to your account. You can determine if your computer has been hacked in one of two ways. Find out if there are computer accounts you have not created, or if any of your legitimate computer accounts have been accessed without your knowledge.

Instructions

1. Log in to your computer as an Administrator.

2. Click the Windows Start button, type "cmd" into the search box and press "Enter" to open a command-line window.

3. Type "net user" without quotes at the command prompt and press "Enter." Windows lists all existing accounts on the computer.

4. Check if an account has been created without your permission. Verify that all accounts in the output of "net user" are legitimate. If there are additional accounts, those accounts were likely created by a hacker.

5. Examine all legitimate accounts to see if any have been misused. Check the date and time of the last login. If the most recent login occurred at an abnormal time, a hacker is likely responsible.
