Start here: the fastest way to get rid of it

If you just want it gone right now: on Windows, go to Settings > Apps > Installed Apps, find Wave Browser, click the three dots, and hit Uninstall. On Mac, quit the app, then drag it from the Applications folder to the Trash and empty it. That’s the core of it, and Wave Browser’s own help center backs this up: uninstall from Installed Apps and confirm when the process finishes.

But here’s the thing most people learn the hard way. Uninstalling once is rarely enough. Wave keeps background processes running, plants startup entries, and leaves browser extensions behind that can pull it right back. So before you celebrate, close the app completely.

Open Task Manager (Ctrl+Shift+Esc on Windows) or Activity Monitor (in Applications > Utilities on Mac), look for anything named Wave, Wave Browser, or Wavesor, and end those tasks first. Removal guides from SafetyDetectives and All About Cookies both stress this order: kill the processes, then uninstall. An app that’s still running mid-uninstall can quietly leave pieces of itself behind.

The full Windows cleanup, step by step

The basic uninstall is the easy 80 percent. The last 20 percent is where Wave tries to survive. Do all of this in order.

  1. End the processes. Ctrl+Shift+Esc opens Task Manager. Under the Processes tab, right-click anything named Wave Browser or Wavesor and choose End Task. Check the Details tab too, since background helpers sometimes hide there.
  2. Uninstall the app. Settings > Apps > Installed Apps (on Windows 10 it’s Settings > Apps > Apps & features). Find Wave Browser, click the three dots or the entry itself, and select Uninstall. Follow the prompts.
  3. Disable startup entries. Back in Task Manager, open the Startup apps tab and disable anything tied to Wave or Wavesor. This is the single most common reason it “comes back” after a reboot.
  4. Clean your browsers. In Chrome, go to chrome://extensions and remove any Wave-related add-on. Do the same in Edge (edge://extensions), Firefox, and any other browser. Then check your homepage and default search engine settings, because Wave likes to hijack those.
  5. Delete leftover files. Press Win+R, type %localappdata% and %appdata% (check both), and delete any folder named Wave, WaveBrowser, or Wavesor.

One warning about the registry. Some guides tell you to go digging through the Windows registry to delete Wave keys by hand. Skip that unless you genuinely know what you’re doing. A wrong delete in the registry can break unrelated software or Windows itself, and there’s no clean undo. A reputable anti-malware scan handles registry remnants without the risk.

Removing Wave Browser from a Mac

Mac users sometimes assume the platform cleans up after itself. It doesn’t, not here. Nektony’s 2026 Mac removal guide is blunt about it: quit the app, check Activity Monitor, and hunt down leftover files in the Library folders.

Start by quitting Wave Browser fully (Cmd+Q, not just closing the window). Open Activity Monitor from Applications > Utilities, search for Wave, and force-quit any matching process. Then open the Applications folder, drag Wave Browser to the Trash, and empty it.

Now the part people miss. In Finder, hit Cmd+Shift+G and check these locations for Wave-related files:

Delete anything with Wave or Wavesor in the name. Then open System Settings > General > Login Items and remove any Wave entry so it can’t relaunch at startup. Finally, clean your browser extensions in Safari, Chrome, and Firefox the same way you would on Windows.

Why it keeps coming back, and the advice that won’t fix it

If Wave reappears after you thought you nuked it, the culprit is almost always one of three things: a startup or login item you didn’t disable, a browser extension still sitting in Chrome or Edge, or a leftover process that respawns the installer. Deal with all three and the resurrection stops.

Here’s where a lot of guides go wrong. Plenty of them stop at “uninstall from Apps and you’re done.” You’re not. As SafetyDetectives and All About Cookies both point out, basic uninstalling leaves remnants behind: background tasks, extensions, registry entries, and Library folders. Treating the uninstall as the finish line is exactly how people end up searching this a second time a week later.

A related trap: assuming it always shows up under the obvious name. It doesn’t. Some installs use publisher aliases, and removal guides mention identifiers like Wavesor, ISIGN International, and Eightpoint. When you’re scanning Task Manager, your installed apps list, or your Library folders, keep an eye out for those names too, not just “Wave Browser.”

Is it malware? That’s the other overblown claim. Most security sites, including proPrivacy and All About Cookies, describe Wave Browser as a potentially unwanted program rather than outright malware. It’s intrusive, it bundles itself into other installers, and it’s a nuisance. But the label matters less than the fix, and the fix is the same either way.

Confirming it’s actually gone

Don’t take it on faith. Verify.

Reboot your computer first, since some remnants only reveal themselves after a restart. Then check three places: your installed apps list should show no Wave entry, Task Manager or Activity Monitor should show no Wave or Wavesor process, and your browsers should have no unfamiliar extensions and your normal homepage and search engine restored.

The final step nearly every security source agrees on is to run a full scan with reputable antivirus or anti-malware software after removal. This catches leftover files, registry traces, and anything bundled alongside Wave that manual cleanup missed. Consider it the receipt that proves the job’s done.

If Wave still won’t leave after all this, your best next move is a dedicated anti-malware tool run in safe mode, or a direct question to the Microsoft community forums, where recent 2026 threads cover exactly this pop-up-and-reinstall behavior. Given that people are still accidentally installing Wave Browser in 2026 and the product is still being actively marketed, this isn’t going away soon. Clean it out thoroughly today — processes, startup items, extensions, and all — and you won’t be back here next month.
