Remove Unauthorized Remote Access Software: Windows & Mac

This guide walks you through identifying and removing unauthorized remote access software from Windows and macOS. You’ll learn where these programs hide, how to spot them, and the exact steps to delete them and secure your device against future intrusions.

What You’ll Need

• Administrator access on the computer (you’ll need to enter an admin password or confirm a UAC prompt).
• An up-to-date antivirus or antimalware scanner (Windows Security on Windows, or a reputable third-party tool on Mac).
• A stable internet connection to download removal tools if needed.
• About 30–45 minutes of uninterrupted time.

Step-by-Step

For Windows

1. Disconnect from the internet. Unplug the Ethernet cable or turn off Wi-Fi. This cuts off the attacker’s connection while you work.
2. Open Task Manager. Press Ctrl+Shift+Esc. Go to the Startup tab and look for unfamiliar programs that auto-start. Common remote access tools include TeamViewer, AnyDesk, Ammyy Admin, and UltraVNC, but attackers may rename them.
3. Check running processes. In the Processes tab, look for names like tv_w32.exe, AnyDesk.exe, Ammyy.exe, or anything you don’t recognize. Right-click and select End Task to stop it temporarily.
4. Uninstall the software. Go to Settings > Apps > Installed apps. Sort by install date and look for entries added around the time you suspect compromise. Click the three dots and choose Uninstall. Follow the prompts.
5. Remove leftover files. Press Win+R, type %temp% and delete contents. Then check C:\Program Files and C:\Program Files (x86) for folders related to the removed software and delete them.
6. Clean the registry. Press Win+R, type regedit. Navigate to HKEY_CURRENT_USER\Software and HKEY_LOCAL_MACHINE\Software. Look for keys with the software’s name or publisher. Right-click and delete. Be careful—only delete keys you’re sure about.
7. Run a full antivirus scan. Open Windows Security, go to Virus & threat protection, and select Scan options > Full scan. This catches any remaining executables or backdoors.
8. Check firewall rules. Open Windows Defender Firewall with Advanced Security. Look for inbound rules that allow connections to unknown programs. Disable or delete any you didn’t create.
9. Reconnect and update. Plug back in, run Windows Update, and change all your passwords from a different, trusted device.

For macOS

1. Disconnect from the internet. Turn off Wi-Fi or unplug Ethernet.
2. Open Activity Monitor. Go to Applications > Utilities > Activity Monitor. Look for processes like RemoteManagementAgent, TeamViewer, AnyDesk, or anything with a name you don’t recognize. Note the process name.
3. Quit the process. Select it and click the X button in the toolbar, then choose Force Quit.
4. Check Login Items. Go to System Settings > General > Login Items. Remove any entries you didn’t add by selecting them and clicking the minus button.
5. Uninstall the app. Open Finder, go to Applications. Drag the suspicious app to the Trash. If it asks for a password, enter your admin password.
6. Remove preference files. In Finder, press Cmd+Shift+G and type ~/Library/LaunchAgents. Look for plist files with names like com.teamviewer.plist or com.anydesk.plist. Delete them. Also check /Library/LaunchAgents and /Library/LaunchDaemons (you may need to use Finder’s Go > Go to Folder).
7. Clear caches. Go to ~/Library/Caches and delete folders related to the software. Empty the Trash.
8. Run a malware scan. Use the built-in XProtect (it runs automatically) or a trusted third-party scanner like Malwarebytes for Mac. Do a full scan.
9. Check Screen Sharing settings. Go to System Settings > General > Sharing. Turn off Screen Sharing and Remote Management if you don’t use them.
10. Reconnect and update. Re-enable internet, run Software Update, and change your passwords.

Common Mistakes

• Only uninstalling without stopping processes. Some remote access tools reinstall themselves if the process is still running.
• Forgetting about browser extensions. Some remote access is delivered via malicious browser extensions. Check your browser’s extensions and remove any you don’t recognize.
• Skipping the registry or LaunchAgents. These are common persistence points. If you miss them, the software can come back.
• Not changing passwords afterward. Even if you remove the software, the attacker may have captured credentials. Change all important passwords.
• Ignoring other devices. If one computer was compromised, others on the same network might be too. Scan them all.

Tips

• Use a reputable antivirus that includes real-time protection. Keep it updated.
• Enable automatic operating system updates to patch vulnerabilities.
• Use a standard (non-admin) user account for daily tasks. Admin rights are only needed for installations.
• Be cautious about clicking links or attachments in unsolicited emails—this is a common way remote access tools get installed.
• If you use legitimate remote access software (e.g., for work), keep it updated and enable two-factor authentication.

Troubleshooting

If the software reappears after removal: It likely left a scheduled task or a service. On Windows, open Task Scheduler and look for tasks with unfamiliar names. On Mac, check /Library/LaunchDaemons again. Delete any related entries.

If you can’t uninstall because the program is locked: On Windows, restart in Safe Mode (Shift + Restart) and try again. On Mac, try booting into Safe Mode (hold Shift during startup) and then remove the app.

If you can’t find the software but still suspect compromise: Use a dedicated removal tool like Malwarebytes (free version) for both platforms. It can detect hidden remote access tools.

If the system is completely locked by a ransom-style message: Do not pay. Disconnect from the internet, and consider a clean OS reinstall. This is the most reliable way to remove any persistent malware.

Frequently Asked Questions

Q: How did remote access software get on my computer?
A: Usually through phishing emails, malicious downloads, or by exploiting unpatched vulnerabilities. Sometimes it’s bundled with other software.

Q: Can I tell if someone is remotely controlling my computer right now?
A: Look for unusual mouse movement, programs opening by themselves, or the screen moving without your input. Check Task Manager/Activity Monitor for unknown processes.

Q: Is it enough to just uninstall the remote access app?
A: No. The attacker may have installed backdoors or keyloggers. Always run a full antivirus scan and change your passwords.

Q: Will removing the software affect my legitimate remote access tools?
A: Only if you remove those specific programs. Be sure you only delete what you didn’t install yourself.

Q: Should I do a factory reset instead?
A: If you can’t remove the software or if you’re not confident, a clean OS reinstall is the safest option. Back up your important files first, but scan them before restoring.

Q: How can I prevent this from happening again?
A: Use strong, unique passwords, enable two-factor authentication, keep software updated, and avoid clicking on unexpected links or attachments.
