Closes your browsers properly
Each window is asked to close gracefully first, so the browser records a clean shutdown and won't offer to restore your tabs. Anything left running is then terminated.

Popups won't stop?
Kill them all at once.
AdKilla closes every open browser, resets the tabs that keep reopening, and clears recent history — so the pop-up storm doesn't come back when you reopen Chrome. Your bookmarks and saved passwords are never touched.

One button. Three jobs.
Most “cleaners” ask you twenty questions. AdKilla asks one: are you sure?
Resets the open tabs
The session-restore state is removed, so your browser reopens with a clean slate instead of resurrecting the pop-ups and pop-unders you just closed.
Clears recent history
The history database is cleared on Chromium browsers, so autocomplete stops suggesting the sites that started the mess.
Keeps what matters
Bookmarks and saved passwords are always preserved. Firefox keeps its history too, because it stores history and bookmarks in the same file.
Sharp on 4K
The window, fonts, and icon read your display scaling and size themselves to match — no blurry upscaling on high-DPI monitors.
Finds the culprit
The bundled command-line tool audits your installed extensions and flags side-loaded ones — the usual source of endless popups.
How it works
-
1
Download and run
The installer puts AdKilla in your user folder and adds a Start Menu shortcut. No admin rights required.
-
2
Click Clean My Browsers
Confirm once. A single status line tells you when it's working and when it's finished — that's the whole interface.
-
3
Reopen your browser
It starts fresh: no restored tabs, no popup cascade, bookmarks and logins right where you left them.
For power users
The same download includes adkilla.exe, a command-line version that
prints every file it touches — scriptable, and safe to try with --dry-run.
C:\> adkilla --help
adkilla [options]
--audit List installed browser extensions (read-only, no changes).
--dry-run Show what would be done without changing anything.
--tabs-only Reset open tabs only; keep browsing history.
--force Terminate browsers immediately (skip graceful close).
--yes, -y Do not prompt for confirmation.
--help, -h Show this help.Treating the symptom, not the disease
AdKilla clears the mess popups leave behind. If they come back after a reboot,
the machine almost certainly has adware or a malicious browser extension.
Run adkilla --audit to spot it, remove anything you don't recognise
from your browser's extensions page (chrome://extensions,
edge://extensions, or about:addons in Firefox), and run a
reputable anti-malware scan.
Questions
Will I lose my bookmarks or passwords?
No. AdKilla never touches bookmark or password storage. It removes session-restore state and, on Chromium browsers, the history database — nothing else.
Does it need administrator rights?
No. The installer is per-user and goes into %LOCALAPPDATA%\Programs\AdKilla, so there's no UAC prompt. It registers a normal uninstaller in Apps & features.
What happens to Firefox?
Firefox stores history and bookmarks in the same database, so AdKilla only resets its open tabs and leaves history alone. Deleting your bookmarks to close a popup would be a bad trade.
Is it really free?
Yes — freeware, by Paige Julianne Sullivan. No account, no subscription, no telemetry, no bundled extras.
Which Windows versions are supported?
64-bit Windows 10 and Windows 11.
Can I run it without installing?
Yes. The GUI (adkilla-gui.exe) and the command-line tool (adkilla.exe) are self-contained executables — the installer just adds shortcuts and an uninstall entry.
