Imgdelnw.com is a browser hijacker that forcibly redirects your web traffic through its own search portal, typically arriving bundled with free software downloads or disguised as a browser extension. Once installed, it alters your browser's default search engine, homepage, and new tab settings without meaningful consent, steering you toward sponsored results and affiliate links that generate revenue for its operators. While not a virus in the traditional sense, this potentially unwanted program (PUP) degrades your browsing experience, exposes you to questionable advertising networks, and proves stubbornly resistant to removal through normal browser settings.

How It Spreads
Imgdelnw.com doesn't break into your system through security vulnerabilities—instead, it tricks you into installing it voluntarily, then hides its true nature until it's already embedded in your browser. The most common infection vector is software bundling, where the hijacker piggybacks on legitimate-looking free applications. When you download a PDF converter, video codec pack, or system optimizer from a third-party download site, the installer often includes "recommended" software in pre-checked boxes buried in the Advanced/Custom installation screens. Users who click through with Express/Typical settings inadvertently authorize the hijacker's installation.
Fake update notifications represent another significant distribution method. You might encounter a webpage claiming your browser, Flash Player, or video codec is outdated, complete with official-looking logos and urgent language. Clicking "Update Now" downloads an installer that delivers Imgdelnw.com instead of (or alongside) the promised update. Deceptive browser extension prompts work similarly—an extension marketed as a shopping helper, weather widget, or productivity tool actually contains hijacker functionality that only reveals itself after installation.
- Software bundle installers from download portals like Softonic, Download.com clones, and torrent sites
- Fake browser/Flash/codec update prompts on compromised or ad-heavy websites
- Deceptive browser extensions advertised through pop-ups or social media ads
- Malvertising campaigns on legitimate sites serving compromised ad content
- Email attachments or links in phishing messages disguised as software recommendations
- Infected USB drives or shared network folders containing bundled installers
What It Does On Your Machine
Once Imgdelnw.com establishes itself, its first action is commandeering your browser's core navigation settings. Your homepage suddenly points to imgdelnw.com or a related redirect domain. Your default search engine switches to an unfamiliar search portal—often one that mimics Google's appearance but serves entirely different results. Every new tab you open loads the hijacker's page instead of your preferred blank page or custom dashboard. When you attempt to reverse these changes through browser settings, you'll find they either revert immediately upon browser restart or the settings interface prevents modification altogether.
The hijacker's revenue model depends on steering your web traffic through its affiliate network. When you perform a search, your query travels through the imgdelnw.com domain, which logs your search terms and IP address before redirecting you through one or more intermediary servers. These redirect hops allow the operators to claim affiliate credit for your eventual arrival at a legitimate search engine or sponsored result page. Along the way, you encounter injected advertisements, promoted links disguised as organic results, and banners for questionable software or services. The redirect chain adds perceptible latency to every search—what should take milliseconds now involves multiple server hops across different networks.
Beyond the visible browser disruption, the hijacker typically installs persistence mechanisms that survive simple extension removal. On Windows systems, it may create scheduled tasks that reinstall browser components at logon or periodic intervals. It might add registry entries that override browser policies, preventing you from changing search settings. On macOS, configuration profiles can enforce the hijacker's settings at the system level. Browser shortcuts on your desktop or taskbar may be modified with command-line arguments that launch directly to the hijacker's domain, bypassing your configured homepage.
Manual Removal — Step by Step
Disconnect and Document Current Settings
Disconnect your computer from the internet (unplug Ethernet or disable Wi-Fi) to prevent the hijacker from downloading additional components during removal. Open a notepad and write down what your homepage, search engine, and new tab settings have been changed to—you'll need this information to identify related extensions and policies. Take screenshots of any unfamiliar browser extensions currently installed.
Boot into Safe Mode with Networking
Restart your computer into Safe Mode with Networking (Windows: hold Shift while clicking Restart, then Troubleshoot > Advanced Options > Startup Settings > Restart > press 5; macOS: restart and hold Shift immediately after hearing startup sound). This prevents most persistence mechanisms from reactivating during the removal process while still allowing you to download tools if needed.
Uninstall Suspicious Programs
Open Windows Settings > Apps > Apps & features (or Control Panel > Programs and Features on older Windows). Sort by install date and look for unfamiliar programs installed around the time the hijacking began. Uninstall anything you don't recognize, especially items with generic names like "Browser Helper," "Search Manager," or publishers you've never heard of. On macOS, check Applications folder and remove suspicious items to Trash, then empty Trash.
Remove Browser Extensions in All Browsers
Open each browser you have installed (Chrome, Firefox, Edge, Safari) and navigate to the extensions/add-ons management page. Remove ALL extensions you didn't intentionally install, plus any that were installed on the date of infection. In Chrome: three-dot menu > Extensions > Manage Extensions, then click Remove. In Firefox: three-bar menu > Add-ons and themes > Extensions, then Remove. Don't assume an extension is safe just because it has an innocent-sounding name—hijackers often use names like "Shopping Helper" or "Translator."
Delete Browser Policies and Reset Shortcuts
Press Windows+R, type regedit, and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome and \Mozilla\Firefox (if these keys exist). Delete the Chrome and Firefox policy keys entirely if found. Next, right-click your browser shortcuts (desktop, taskbar, Start menu), select Properties, and examine the Target field—remove any web addresses or command-line arguments after the .exe path, leaving only the quoted path to the browser executable.
Check and Remove Scheduled Tasks
Open Task Scheduler (type "task scheduler" in Windows search). Expand Task Scheduler Library and review the task list for entries with generic names or unfamiliar publishers created around the infection date. Right-click suspicious tasks and select Delete. Common hijacker task names include "Browser Update," "System Check," or random alphanumeric strings. On macOS, check System Preferences > Users & Groups > Login Items and remove unfamiliar entries.
Reset Browser Settings to Default
In each browser, access the reset function: Chrome (Settings > Reset and clean up > Restore settings to original defaults); Firefox (Help > More troubleshooting information > Refresh Firefox); Edge (Settings > Reset settings > Restore settings to default values). This removes lingering preference changes the hijacker made. You'll need to reconfigure your personal settings afterward, but your bookmarks and passwords are preserved.
Run Malwarebytes or Similar Reputable Scanner
Reconnect to the internet and download Malwarebytes Free from malwarebytes.com (verify you're on the legitimate site). Run a full Threat Scan, which typically takes 20-40 minutes. Quarantine and remove everything it finds. Follow up with a second-opinion scan using HitmanPro or AdwCleaner (both from reputable sources). These tools catch hijacker remnants that manual removal might miss, including browser helper objects and registry artifacts.
Verify and Reconfigure Browser Settings
Open each browser and manually set your preferred homepage, search engine, and new tab page. Test by performing several searches and opening new tabs—verify you're getting results from your chosen search engine without unexpected redirects. Clear browsing data (cache, cookies, site data) from the past week to remove tracking artifacts the hijacker left behind. Check that your search suggestions and address bar behavior are working normally.
Reboot Normally and Monitor for Recurrence
Restart your computer normally (exit Safe Mode) and use your browsers for an hour, paying attention to any automatic setting changes or unexpected redirects. If the hijacker reappears, a persistence mechanism survived—you'll need professional removal or a more aggressive cleanup. Change passwords for important accounts if you entered credentials while the hijacker was active, as your browsing data was being monitored and transmitted.
Prevention
- Download software only from official publisher websites or the Microsoft Store. Third-party download portals routinely bundle PUPs with legitimate software. When you need a free program, search for the developer's official site and download directly from there.
- Always choose Custom/Advanced installation options and read every screen carefully. Deselect any pre-checked offers for additional software, browser toolbars, or homepage changes. If an installer doesn't offer Custom installation, that's a red flag—cancel and find the software elsewhere.
- Keep your browser and operating system updated. Enable automatic updates for Windows/macOS and all browsers. Security patches close vulnerabilities that hijackers sometimes exploit to bypass user consent during installation.
- Install a reputable ad-blocker extension like uBlock Origin (not AdBlock Plus, which allows some ads through). Ad-blockers prevent malicious advertising that delivers hijacker payloads and block many fake update prompts before you see them.
- Treat all unsolicited update prompts as suspicious. Legitimate software updates through the program's built-in update mechanism or official app stores—never through random website pop-ups. When in doubt, manually check for updates through the application's Help menu.
- Review installed browser extensions quarterly. Set a calendar reminder to audit your extensions every three months. Remove anything you don't actively use or don't remember installing. Extensions you installed years ago may have been sold to new owners with less scrupulous practices.
- Use standard (non-administrator) user accounts for daily computing. Hijackers can install more persistent system-level components when you're logged in as an administrator. Create a standard user account for web browsing and everyday tasks, using the admin account only for legitimate software installations.
- Be cautious with browser permission requests. When a website asks for notification permissions, location access, or other capabilities, deny by default unless you have a specific, ongoing need for that functionality on that site. Many hijackers leverage overly permissive browser permissions.
