JarteauSedLive is a browser hijacker and potentially unwanted program (PUP) that infiltrates Windows systems primarily through software bundling and deceptive advertising networks. Once installed, it modifies browser settings without user consent, redirects search queries through questionable intermediary servers, and injects unwanted advertisements into web pages. While not classified as a traditional virus or trojan, JarteauSedLive exhibits aggressive persistence mechanisms and data-collection behaviors that compromise both system performance and user privacy. Users typically notice unexplained homepage changes, search engine replacements, and an increased volume of pop-up advertisements appearing during normal browsing sessions.

How It Spreads
JarteauSedLive rarely arrives on systems through direct user action. Instead, it leverages deceptive distribution tactics that exploit user inattention during software installations and updates. The most common infection vector involves software bundlers—third-party download managers that package legitimate free software with additional "offers" that install browser hijackers. Users downloading video converters, PDF tools, or media players from unofficial sources frequently encounter these bundles. During installation, pre-checked boxes or deliberately confusing language attempts to gain consent for the hijacker's installation alongside the desired program.
Malicious advertising networks represent another significant distribution channel. Compromised websites or legitimate sites running insufficiently vetted ad networks may serve advertisements containing fake download buttons, fraudulent software update notifications, or alerts claiming system infections. Clicking these deceptive elements initiates downloads of trojanized installers that deploy JarteauSedLive. The hijacker also spreads through fake browser extension repositories and phishing emails containing attachments that masquerade as document readers or system utilities.
Common infection pathways include:
- Bundled installers from unofficial download sites (softonic-style aggregators, torrent-adjacent software repositories)
- Fake update prompts claiming Adobe Flash, Java, or browser updates are required to view content
- Malvertising campaigns on streaming sites, file-sharing platforms, and adult content sites
- Browser extension spoofing where the hijacker mimics legitimate productivity extensions
- Email attachments disguised as invoices, shipping notifications, or document viewers
- Compromised freeware where legitimate software repositories are temporarily poisoned with modified installers
What It Does On Your Machine
Upon successful installation, JarteauSedLive immediately targets browser configurations across all installed web browsers. It replaces the default homepage with search.jarteausedlive.com or a variant domain, changes the default search engine to route queries through its monetization infrastructure, and may install a browser extension to maintain these changes. The hijacker modifies browser shortcut files by appending command-line parameters that force the hijacked homepage to load regardless of user preferences. This creates the frustrating experience where users reset their browser settings only to find them hijacked again after the next launch.
The primary function of JarteauSedLive is traffic monetization through forced redirections and advertisement injection. When users perform web searches, queries first pass through the hijacker's servers, which log the search terms and redirect users through affiliate networks before eventually delivering modified search results. These results prioritize sponsored links and advertisements over organic results. During normal browsing, the hijacker injects additional advertisements into legitimate websites—pop-unders, banner ads, in-text link advertisements, and video overlays that weren't placed by the site's operators. Each clicked advertisement generates revenue for the hijacker's operators through affiliate programs.
Beyond advertisement monetization, JarteauSedLive functions as a data-collection platform. It tracks browsing activity, search queries, clicked links, and time spent on various websites. This information profiles user interests and browsing habits for targeted advertising purposes. While the hijacker doesn't typically capture passwords or financial data directly, it creates privacy risks by sharing browsing data with third-party advertising networks whose data-handling practices remain opaque. The constant network communication and ad-injection processes consume system resources, leading to slower browser performance, increased memory usage, and occasional browser crashes when the injection mechanisms conflict with website code.
The hijacker establishes multiple persistence mechanisms to survive basic removal attempts. Beyond the browser extension, it typically creates scheduled tasks that monitor browser configurations and reinstall components when they're removed. Registry modifications ensure the hijacker's components launch during system startup. Some variants monitor browser processes and revert configuration changes in real-time, requiring users to remove all persistence mechanisms simultaneously for successful remediation.
Manual Removal — Step by Step
Disconnect from Network and Document Current State
Before making any changes, disconnect your computer from the internet (unplug Ethernet or disable Wi-Fi). This prevents the hijacker from receiving updated configurations or downloading additional components during removal. Take screenshots of your current browser homepage, default search engine, and installed extensions so you can verify complete removal later. Note any unusual browser behavior you're experiencing.
Boot Into Safe Mode with Networking
Restart your computer and enter Safe Mode with Networking. On Windows 10/11, hold Shift while clicking Restart, then navigate to Troubleshoot > Advanced Options > Startup Settings > Restart, and select Safe Mode with Networking (option 5). Safe Mode loads only essential drivers and services, preventing the hijacker's persistence mechanisms from reactivating during removal. The networking capability allows you to download removal tools if needed.
Uninstall Suspicious Programs
Open Settings > Apps > Apps & features (or Control Panel > Programs and Features on older Windows). Sort by installation date and look for recently installed programs you don't recognize, especially those installed around the time browser issues began. Uninstall anything named JarteauSedLive, Jarteau, or any unfamiliar programs installed on the same date. Be thorough—hijackers often install with generic names like "System Updater" or "Media Viewer." If the uninstaller offers to keep settings or data, decline and choose complete removal.
Remove Browser Extensions and Reset Shortcuts
Open each installed browser and remove all extensions you didn't intentionally install. In Chrome, navigate to chrome://extensions/, enable Developer Mode, and remove suspicious extensions. In Firefox, go to about:addons. After removing extensions, right-click each browser shortcut (on desktop, taskbar, Start menu), select Properties, and examine the Target field. Remove any text after the .exe filename (especially --homepage flags). Click OK to save. This prevents the hijacker from forcing its homepage on browser launch.
Delete Scheduled Tasks
Open Task Scheduler (search for "Task Scheduler" in the Start menu). Expand Task Scheduler Library and look for tasks with names containing "JarteauSedLive," "Update," or random alphanumeric strings created recently. Select each suspicious task, note the action it performs (usually running an executable from AppData or ProgramFiles), then right-click and delete the task. This prevents automatic reinstallation of hijacker components.
Clean Registry Persistence Keys
Press Windows+R, type "regedit," and press Enter. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and look for entries with suspicious names or paths pointing to folders in %LOCALAPPDATA% or %APPDATA%. Delete entries related to JarteauSedLive. Also check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run for system-wide startup entries. Be cautious—only delete entries you can positively identify as related to the hijacker. If uncertain, note the entry name and research it before deletion.
Delete Hijacker Files and Folders
Open File Explorer and navigate to %LOCALAPPDATA% (paste this into the address bar). Look for folders with random GUIDs or names containing "Jarteau" or "SedLive." Delete these entire folders. Repeat for %APPDATA% and %PROGRAMFILES(X86)%. If you receive "file in use" errors, the process may still be running—open Task Manager, find processes with suspicious names or running from the folders you're trying to delete, end those processes, then retry deletion. Empty the Recycle Bin when finished.
Run Malwarebytes and Full System Scan
Download and install Malwarebytes Free (from the official malwarebytes.com site only—ensure you're in Safe Mode with Networking). Run a full Threat Scan, which typically takes 30-60 minutes. Malwarebytes excels at detecting browser hijackers and PUPs that traditional antivirus might miss. Quarantine all detected items. If Malwarebytes finds additional components, make note of their locations to verify manual removal was complete. Restart the computer after quarantine to allow Malwarebytes to finalize removal.
Reset Browser Settings Completely
After restarting in normal mode, open each browser and perform a settings reset. In Chrome, go to Settings > Reset settings > Restore settings to their original defaults. In Firefox, visit about:support and click Refresh Firefox. In Edge, go to Settings > Reset settings > Restore settings to their default values. This removes any lingering configuration changes the hijacker made. You'll need to re-enter your homepage preference and default search engine, but extensions you intentionally use should remain (verify these afterward).
Verify Removal and Change Passwords
Reconnect to the internet and test each browser. Verify your homepage loads correctly, search queries use your chosen search engine, and no unexpected advertisements appear. Check Task Manager for unusual processes consuming resources. If browser behavior is normal for several hours of use, the hijacker is likely removed. As a precaution, change passwords for important accounts (email, banking, social media) from a clean browser session, since the hijacker was logging browsing activity and could have captured login pages visited during infection.
Prevention
- Download software only from official sources. Avoid third-party download aggregators, torrent sites for commercial software, and unofficial mirrors. Go directly to the developer's website or use the Microsoft Store for Windows applications. When you must use a download site, carefully read each installation screen and decline any "recommended" additional software.
- Read installation prompts carefully and choose Custom/Advanced installation. Never click through installers using Express/Recommended options without reading what's being installed. Custom installation reveals bundled offers that you can deselect. Look for pre-checked boxes offering toolbars, search engine changes, or "useful utilities"—uncheck all of these.
- Keep browsers and operating system updated. Enable automatic updates for Windows and all browsers. Security patches close vulnerabilities that malvertising campaigns exploit. Updated browsers also include improved protections against extension abuse and unauthorized settings modifications.
- Install a reputable ad-blocker and script-blocker. Browser extensions like uBlock Origin (not "uBlock"—different product) block malicious advertisements before they can execute. Script-blockers like NoScript or uMatrix prevent drive-by downloads, though they require more configuration. These tools eliminate most malvertising infection vectors.
- Maintain real-time antivirus with PUP detection enabled. Windows Defender is adequate if you enable PUP/PUA detection in Windows Security settings. Third-party options like Bitdefender or Kaspersky offer additional layers. Ensure your antivirus is configured to scan downloads in real-time and to detect potentially unwanted applications, not just traditional malware.
- Be skeptical of update prompts within web pages. Legitimate software updates come through the application itself or Windows Update, never through pop-ups while browsing. If a website claims you need to update Flash, Java, or your browser to view content, navigate away—these are almost always fake update scams distributing malware.
- Review installed programs and browser extensions monthly. Schedule a recurring reminder to check Apps & Features for unfamiliar programs and review browser extensions. Remove anything you don't recognize or actively use. Browser hijackers sometimes install silently and remain dormant before activating, so regular audits catch infections early.
- Create a standard user account for daily use. Instead of using an administrator account for routine browsing and work, create a standard user account with limited privileges. This prevents installers (including malicious ones) from making system-wide changes without explicit administrator approval via UAC prompts, adding a critical barrier to infection.
