Comodo Dragon was one of those browsers that sounded great on paper—marketed as a more secure version of Chrome, built on the same Chromium engine but with extra privacy features, like blocking certificate warnings and encrypting your searches. I installed it a few years back when I was paranoid about public Wi-Fi and thought having “military-grade” security in a browser would help. It looked like Chrome, worked like Chrome, but came bundled with Comodo’s own certificate verifier and a few background services that ran constantly. The problem? It’s discontinued. Comodo stopped updating it years ago, and while it might’ve been secure back then, running it now is a risk. But the real headache starts when you try to remove it. It doesn’t just install in one folder—it drops components in AppData, creates registry entries, sets up a silent updater service, and hijacks your default browser settings. Even after uninstalling, I’ve seen it leave behind the “DragonUpdater” service still trying to run at startup, or remnants of its SSL verification tool causing conflicts with real antivirus software. And because it mimics Chrome so closely, Windows sometimes doesn’t recognize it as a separate app, making it harder to fully clean out.
Uninstalling Comodo Dragon on Windows 10:
I’ve had to wipe this off a couple of machines, and doing it right takes more than one pass. Start by pressing Windows + I to open Settings, then go to Apps > Apps & features. Search for “Comodo Dragon.” If it shows up, click it, then Uninstall, and follow the prompts. This should launch the built-in uninstaller. Let it run, but don’t assume it did the job.
Now, press Windows + R, type appwiz.cpl, and hit Enter. This opens the old-school Programs and Features window. Scroll through and look for “Comodo Dragon” or anything under “Comodo Group.” If it’s still there, uninstall it again. Sometimes the Settings app misses it, but this one catches it.
Next, the manual cleanup. Open File Explorer and go to:
C:\Program Files\Comodo\Comodo Dragon\C:\Program Files (x86)\Comodo\Comodo Dragon\C:\Users\[YourName]\AppData\Local\Comodo\Comodo Dragon\C:\Users\[YourName]\AppData\Roaming\Comodo\Comodo Dragon\
Delete all these folders. The AppData ones are hidden, so either enable “Hidden items” in the View tab or paste %localappdata%\Comodo\Comodo Dragon and %appdata%\Comodo\Comodo Dragon directly into the address bar.
Also, press Windows + R, type %temp%, and delete any temporary files related to Comodo Dragon.
Now, stop the background updater. Open Task Manager (Ctrl+Shift+Esc), go to the Startup tab, and look for “DragonUpdater” or “Comodo.Dragon.Updater.” Right-click and Disable it.
Then go to the Services tab in Task Manager, find “DragonUpdaterService,” right-click, and go to Go to Service(s). In the Services app (search in Start), stop the service and set its Startup type to Disabled.
Fix your default browser: go back to Settings > Apps > Default apps, click Web browser, and set it to Chrome, Edge, or whatever you actually use. Dragon loves to grab this without asking.
Now, clean the registry. Press Windows + R, type regedit, and back up your registry first—right-click “This PC” > Export, and save it. Then go to:
HKEY_CURRENT_USER\Software\Comodo\Comodo DragonHKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Comodo\Comodo Dragon
Delete these keys. Also, check:
HKEY_CLASSES_ROOT\http\shell\open\commandHKEY_CLASSES_ROOT\https\shell\open\command
Make sure they’re not pointing to Dragon.exe.
Uninstalling Comodo Dragon on Windows 11:
The process is almost the same, but Windows 11 hides some paths a little deeper. Click Start, press Windows + I, go to Apps > Installed apps. Search for “Comodo Dragon.” When it appears, click the three dots (⋯) and select Uninstall. Run through the steps.
But again, it might not be fully gone. Press Windows + R, type appwiz.cpl, and check the full list. Remove any related entries.
Now, manually delete leftovers. Go to:
C:\Program Files\Comodo\Comodo Dragon\C:\Users\[YourName]\AppData\Local\Comodo\Comodo Dragon\C:\Users\[YourName]\AppData\Roaming\Comodo\Comodo Dragon\
Use Run with %localappdata%\Comodo\Comodo Dragon and %appdata%\Comodo\Comodo Dragon to get there fast.
Open Task Manager, go to Startup, and disable any Comodo Dragon entries.
Open Services, stop and disable the “DragonUpdaterService.”
Fix your default browser: go to Settings > Apps > Default apps, then click Set defaults by app or Choose default apps by protocol, and reassign HTTP, HTTPS, and HTML file types to your preferred browser.
For the registry, same as before: use regedit, back up first, then remove all Comodo Dragon keys under HKEY_CURRENT_USER\Software\Comodo and HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Comodo. Be careful not to touch other Comodo tools unless you’re removing those too.
Even after all this, I’ve seen the updater service reappear after a system restore or Windows update. That’s why I don’t waste time on manual removal anymore. I use PerfectUninstaller. It scans deep—finds hidden services, browser hijackers, leftover files, and registry junk that Comodo leaves behind. It removes everything in one click, and actually stays gone. No more background processes, no homepage changes, no weird security warnings. If you’re serious about cleaning your system without the hassle, just use PerfectUninstaller. It’s the only tool I trust to make sure Comodo Dragon doesn’t keep sneaking back in.
