wavebrowser.exe is the Windows executable associated with Wave Browser, a Chromium-based browser from Wavesor Software. The filename by itself does not prove that a file is malware. However, an installation you do not remember approving deserves investigation: Malwarebytes detects some distributions as PUP.Optional.Wave, and an ANY.RUN sandbox report dated March 5, 2026 labeled one submitted sample “Malicious activity.”
Use the file’s source, signer, version, hash, location and behavior to judge the copy on your PC, then remove it with the Windows and security-tool steps below.

What wavebrowser.exe is
Wave Browser is a Chromium-based web browser. Its Windows program file is commonly named wavebrowser.exe or WaveBrowser.exe. It is ordinary application software, not a Windows system component required for booting, networking or basic desktop operation. Removing the browser will not remove Windows itself, although other Wave files can remain until the uninstall process and a security scan finish.

The name is not a unique security identity. Any program can be given the same filename, and a legitimate installer can be repackaged or distributed through a channel that you did not authorize. Judge the individual file rather than trusting—or condemning—the name alone.

Is wavebrowser.exe a virus?
There is no single answer that applies to every copy. The available evidence describes different products, distributions and samples:
| Evidence | What it says | How to interpret it |
|---|---|---|
| Wave Browser Support, September 11, 2023 | The vendor says, “No, Wave Browser is not malware,” and describes a browser built on the open-source Chromium Web core. | This is the publisher’s position, not an independent guarantee for every installer or later build. |
| AppEsteem directory, entries shown for 2025–2026 | Active certified-app entries are listed for Wavesor Software. AppEsteem notes that certification requirements change and listed behavior can differ from current requirements. | A listing is useful context for a particular version, but it does not authenticate an arbitrary file on your computer. |
| Malwarebytes detection | PUP.Optional.Wave is its detection name for Wave Browser that qualifies as a potentially unwanted program. Malwarebytes says some distribution channels install it without user consent. | A PUP is unwanted or deceptive software, not automatically a classic virus. An unexpected installation should still be removed and investigated. |
| ANY.RUN report, March 5, 2026 | One submitted PE32 Windows file named WaveBrowser.exe received a “Malicious activity” verdict and opened a wavebrowser.co URL during execution. | This is evidence about that submitted sample and its behavior, not proof that every file with the same name is malicious. |
| Microsoft guidance | Potentially unwanted applications can show unwanted advertising, offer unexpected apps, alter browser settings or perform other actions the user did not request. | Bundling, redirects, excessive messages and loss of browser control are warning signs even when software is not classified as malware. |
Therefore, a Wave Browser installation you intentionally downloaded from a trusted source may be an ordinary browser, while an unrequested copy bundled with another installer may be a PUP. A separately submitted file can also behave maliciously. Your decision should follow the evidence from your own machine.
Why Wave Browser may be on your PC
You installed it deliberately
You may have downloaded Wave Browser yourself, accepted it as part of a software setup, or used an administrator account that installed it for multiple users. Check your download history, software-inventory records and the Windows install date before assuming compromise.

Malwarebytes reports channels that install Wave Browser without clear user consent. Bundled installers can hide an optional browser behind “Recommended” settings, a prechecked box or a misleading button. Microsoft identifies unexpected applications, changed browser settings, intrusive advertising and loss of control as common PUA indicators.
A different file is impersonating it
Attackers can name an executable after a known browser and place it in a temporary, roaming-profile or otherwise unusual directory. A filename that looks familiar is not evidence of a valid publisher signature.
Warning signs that warrant removal
- You do not remember installing Wave Browser or cannot identify the installer that delivered it.
- Your default browser, search engine, new-tab page, shortcuts or extensions changed unexpectedly.
- New tabs, redirects, pop-up advertising or excessive notifications appeared after the installation.
- Wave Browser returns after you uninstall it, or a process starts again from a temporary or user-profile folder.
- Windows Security, another antivirus product or a PUP scanner flags the executable or related files.
- The file has no valid digital signature, has a publisher you do not recognize, or its version and hash differ from the copy you expected.
Check the specific executable before deleting anything
If you need to distinguish a legitimate installation from an unwanted or substituted file, collect these details first. Do not open the browser or sign in to accounts through it while you investigate an unrequested copy.

- Find the running file. Press
Ctrl+Shift+Escto open Task Manager, right-click the Wave Browser process and choose Open file location. If it is not running, search File Explorer forwavebrowser.exe. - Record the full path. A normal program directory can be more reassuring than a randomly named folder under
%TEMP%, but location alone is not proof. Preserve the path for an IT administrator or security vendor. - Inspect the signature. Right-click the file, choose Properties, open Digital Signatures, select the signer and choose Details. A valid signature should show that Windows can verify the file and that the signer is the publisher you expect. An absent or invalid signature is a reason for caution, not conclusive proof of malware.
- Capture version information. In Properties, open Details and note product name, file version, product version and copyright fields.
- Calculate a hash when support is needed. In PowerShell, run
Get-FileHash -Algorithm SHA256 -LiteralPath "C:fullpathwavebrowser.exe", replacing the path with the one you recorded. Save the resulting SHA-256 value with the signer and version. - Identify the installer source. Check browser downloads, email attachments, software deployment logs and the Windows installed-app entry. A file that appeared immediately after an unrelated freeware setup deserves more scrutiny than one you knowingly downloaded.
Do not upload a confidential executable to a public scanner without checking your organization’s policy. Hashes, signatures and local security logs are often enough for an administrator to begin an assessment.

1. Disconnect risky activity
Close Wave Browser and avoid entering passwords or payment details in it. If the machine is showing active redirects, credential prompts or other suspicious behavior, disconnect it from the network while you collect evidence and begin scanning.
2. Uninstall it through Windows
- On Windows 11, open Settings → Apps → Installed apps. On Windows 10, open Settings → Apps → Apps & features.
- Search for Wave Browser, WaveBrowser or an entry from Wavesor Software.
- Select the three-dot menu (Windows 11) or the app entry (Windows 10), choose Uninstall, and complete the wizard.
- If you suspect a recent unwanted installation, sort the installed-app list by install date and review other programs added at the same time. Remove only software you recognize as unnecessary or unwanted.
Uninstalling is safer than deleting wavebrowser.exe directly because it can remove registered components, shortcuts and uninstall information. If Windows reports that the app is running, end its process in Task Manager, restart, and try the uninstall again.
3. Update Microsoft Defender and run a full scan
- Open Windows Security → Virus & threat protection → Protection updates and choose Check for updates.
- Return to Virus & threat protection, choose Scan options, select Full scan, and start the scan.
- Allow Windows Security to quarantine or remove detections. Restart if prompted.
Microsoft recommends current Defender protection and trusted download sources when dealing with potentially unwanted applications.
4. Use Defender Offline if the problem persists
If the process returns, security software cannot remove it, or suspicious activity continues before Windows fully loads, choose Windows Security → Virus & threat protection → Scan options → Microsoft Defender Offline scan → Scan now. Save work first: Windows restarts and scans outside the normal desktop environment.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitches5. Obtain a second-opinion PUP scan
A reputable PUP scanner can identify remnants that a general scan does not classify the same way. Malwarebytes documents this workflow for PUP.Optional.Wave: run a Threat Scan, quarantine the detected items, and reboot when prompted. Review the detection path before quarantine so you can distinguish Wave-related files from a similarly named legitimate program.

6. Restore browser control
- In every installed browser, review extensions and remove ones you did not choose.
- Set your preferred default browser and search engine again.
- Inspect the home page, new-tab page, notification permissions and proxy settings.
- Right-click browser shortcuts, choose Properties, and check that the Target ends with the browser executable rather than an unfamiliar URL or command.
- Open Task Manager’s Startup apps tab and disable an unrecognized Wave-related entry after recording its location.
7. Restart and verify
Restart Windows, confirm that Wave Browser is gone from Installed apps, and watch for its process, shortcuts, extensions or redirects to return. Run another scan if anything reappears. Change passwords from a known-clean browser if you entered credentials into an untrusted installation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Wave-related files and registry traces
Malwarebytes lists possible traces including %APPDATA%Wavesor Software, %USERROOT%Wavesor Software, %PROGRAMFILES%Wavesor Software and Wave Browser shortcuts. It also lists these registry locations:
HKCUSOFTWAREMicrosoftWindowsCurrentVersionUninstallWaveBrowserHKCUSOFTWAREWavesorHKCUSOFTWAREWaveBrowser
These are detection traces, not a checklist that every computer will contain. Do not delete registry keys or folders while the browser is still installed, and create a restore point or backup before manual registry work. After a successful uninstall and reboot, an empty leftover folder can usually be documented and removed, but a locked or returning file should be handled by your security tool or IT administrator.

When the file is probably legitimate—and when it is not
A deliberately installed copy with a verifiable publisher signature, an expected version, a known installer source, no unwanted setting changes and clean scans has a stronger legitimacy case. That still does not make the filename itself a guarantee.
An unrequested copy with bundling evidence, browser hijacking symptoms, an invalid signature, a temporary-folder path or repeated security detections should be treated as potentially unwanted until removed and checked. If a hash or behavior matches a specific malicious report, preserve the evidence and escalate to a security professional rather than trying to “clean” the file by renaming it.
What the conflicting classifications mean
“Malware,” “PUP” and “safe browser” are not interchangeable labels. The vendor statement describes the product as intended by its publisher. Malwarebytes’ label describes a distribution that meets its potentially unwanted-program criteria. The ANY.RUN verdict describes one submitted executable observed in a sandbox. AppEsteem’s directory reflects certification entries whose requirements and covered versions can change. Keeping those scopes separate prevents both false reassurance and an unsupported claim that every Wave Browser file is a virus.
No defensible population statistic establishes how many Windows systems contain wavebrowser.exe. Treat reports as case-specific evidence and assess the installation in front of you.
