MerryXmasPromos1Click is a browser hijacker and potentially unwanted program (PUP) that infiltrates Windows systems by manipulating browser settings and redirecting users to dubious promotional websites. Despite its festive-sounding name, this threat has nothing to do with legitimate holiday shopping offers. Instead, it forces unwanted search redirects, generates intrusive advertisements, and may track your browsing activity to build advertising profiles. Users typically notice their homepage or default search engine has changed without permission, along with an increase in pop-up ads and unexpected redirects to questionable e-commerce sites.
While not as destructive as ransomware or banking trojans, MerryXmasPromos1Click degrades your browsing experience and poses privacy risks. The redirects can expose you to additional malware, phishing schemes, and aggressive adware. More concerning, the tracking components may collect search queries, visited URLs, IP addresses, and even form data—information that gets monetized through advertising networks or potentially sold to third parties.

How It Spreads
MerryXmasPromos1Click rarely arrives alone and almost never through honest disclosure. The most common infection vector is software bundling, where the hijacker piggybacks on legitimate-looking freeware installers. Users download what they believe is a PDF converter, media player, or system utility from a third-party download site, but the installer includes MerryXmasPromos1Click buried in the "recommended" or "custom" installation options. Most people click through the Express Install option without reading the fine print, unwittingly agreeing to install multiple unwanted programs.
Deceptive advertising plays a significant role as well. Malicious ads on file-sharing sites, streaming platforms, and even compromised legitimate websites display fake "Update Required" warnings or download buttons that don't actually lead to the file you wanted. Click one of these, and you're installing the hijacker instead. The threat also spreads through fake browser extensions that promise useful features—ad blockers, coupon finders, weather tools—but deliver unwanted redirects and ads instead.
- Bundled freeware installers from third-party download sites (Softonic, CNET Downloads, file-sharing platforms)
- Fake software updates claiming your Flash Player, Java, or browser needs updating
- Deceptive download buttons on torrent sites and freeware portals designed to mislead users
- Malicious browser extensions offering fake functionality while installing the hijacker
- Email attachments from spam campaigns disguised as holiday promotions or shipping notifications
- Compromised websites serving drive-by download exploits through outdated browser plugins
- Peer-to-peer file sharing where infected files are mislabeled as legitimate software or media
What It Does On Your Machine
Once installed, MerryXmasPromos1Click immediately sets about modifying your browser configuration. Your homepage changes to an unfamiliar search portal, and your default search engine switches to a branded search service that looks legitimate but exists solely to inject advertisements into your search results. When you open a new tab, instead of seeing your normal page or search box, you're presented with promotional content, sponsored links, or redirect chains that bounce through multiple advertising domains before landing on dubious e-commerce sites.
The hijacker installs persistence mechanisms to ensure it survives your attempts to fix your browser settings manually. It adds registry entries that reset your homepage every time you restart the browser. It may modify browser shortcuts on your desktop and taskbar, appending a URL to the target path so the hijacker's page loads automatically on launch. Browser extensions get installed without clear permission, and even when you remove them through the browser's extension manager, they may reinstall themselves through scheduled tasks or startup entries.
Performance degradation follows quickly. Your browser becomes noticeably slower as the hijacker injects advertisements into every webpage you visit. Pop-ups appear with increasing frequency. Banner ads overlay legitimate content. Text on websites gets converted into hyperlinks that trigger more ads when you hover over them. Every search you perform goes through the hijacker's servers before delivering results, adding latency and allowing the threat to log your queries. You may notice your CPU usage spikes when browsing, and your internet bandwidth gets consumed by the constant communication between the hijacker and its advertising network infrastructure.
The privacy implications are substantial. MerryXmasPromos1Click deploys tracking cookies and may install system-level monitoring components that log your browsing behavior across all browsers and applications. This data—which can include personally identifiable information if you've filled out forms or logged into accounts while infected—gets transmitted to remote servers for profiling and monetization. In some variants, the hijacker also watches for banking sites, shopping portals, and login pages, potentially capturing credentials or redirecting you to phishing pages designed to steal your information.
Manual Removal — Step by Step
Disconnect and Document Current Symptoms
Before making changes, disconnect your computer from the internet by disabling Wi-Fi or unplugging the ethernet cable. This prevents the hijacker from downloading additional components or communicating with command-and-control servers. Take screenshots of your current homepage, search engine settings, and any suspicious browser extensions—you'll need to verify these are actually fixed later. Write down which symptoms you're experiencing so you can confirm they're resolved after cleanup.
Boot Into Safe Mode with Networking
Restart your computer in Safe Mode to prevent the hijacker from running its protection mechanisms. On Windows 10/11, hold Shift while clicking Restart, then navigate to Troubleshoot → Advanced Options → Startup Settings → Restart, and press 5 to enable Safe Mode with Networking. Safe Mode loads only essential system processes, making it much easier to identify and remove malicious components without the hijacker actively defending itself.
Uninstall Suspicious Programs
Open Control Panel → Programs and Features (or Settings → Apps on Windows 10/11) and carefully review the installed programs list, sorted by installation date. Look for MerryXmasPromos1Click, any programs you don't recognize installed around the same time you noticed the hijacking, and software with generic names like "Web Companion," "Search Manager," or holiday-themed names. Uninstall anything suspicious, but be aware that the uninstaller may leave remnants behind intentionally.
Remove Browser Extensions Across All Browsers
Open each browser you use and navigate to the extensions/add-ons manager (chrome://extensions in Chrome, about:addons in Firefox, edge://extensions in Edge). Remove any extensions you don't recognize, didn't intentionally install, or that were installed on the same date as the infection. Pay special attention to extensions with vague names like "Helper," "Manager," or holiday-themed titles. Disable "Developer mode" in Chrome's extensions page if it's enabled, as hijackers often use this to install unpacked extensions.
Check and Repair Browser Shortcuts
Right-click each browser shortcut on your desktop and taskbar, select Properties, and examine the Target field. The path should end with the browser's executable (.exe) and nothing else. If you see any URLs or additional parameters after the .exe (like "chrome.exe http://hijacker-site.com"), delete everything after the .exe filename. Hijackers frequently modify shortcuts this way to force their page to load on every browser launch, and this step is commonly overlooked.
Clean the Registry and Scheduled Tasks
Press Windows + R, type "regedit," and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. Look for entries referencing MerryXmasPromos, XmasPromos, or unfamiliar executables in temp folders or AppData locations—delete these entries. Next, press Windows + R again, type "taskschd.msc" to open Task Scheduler, and review the Task Scheduler Library for any tasks named after the hijacker or scheduled to run suspicious executables. Disable and delete these tasks to prevent automatic reinstallation.
Delete Files and Folders
Open File Explorer and enable viewing of hidden files (View → Options → View tab → Show hidden files, folders, and drives). Navigate to C:\Users\[YourUsername]\AppData\Local\ and C:\Users\[YourUsername]\AppData\Roaming\ and delete any folders named MerryXmasPromos, XmasPromos1Click, or containing suspicious executables you identified in the Run registry keys or scheduled tasks. Also check C:\Program Files (x86)\ for any related program folders and delete them. Empty the Recycle Bin when finished.
Run Malwarebytes and a Secondary Scanner
Reconnect to the internet and download Malwarebytes (from malwarebytes.com directly—don't use search results that might lead to fake versions). Install and run a full Threat Scan. Malwarebytes excels at detecting PUPs and browser hijackers that traditional antivirus sometimes misses. After Malwarebytes completes and removes detected threats, run a second scanner like HitmanPro or AdwCleaner to catch anything the first scan missed. Browser hijackers often install in clusters, so redundant scanning is worthwhile.
Reset Browser Settings to Defaults
Even after removing the hijacker, modified settings may persist. In Chrome, go to Settings → Reset settings → Restore settings to their original defaults. In Firefox, go to about:support and click "Refresh Firefox." In Edge, go to Settings → Reset settings → Restore settings to their default values. This clears search engines, homepage settings, and startup pages back to factory defaults. You'll need to reconfigure your preferences afterward, but it ensures no hijacker remnants remain in configuration files.
Reboot, Verify, and Update Passwords
Restart your computer normally (not in Safe Mode) and verify that your homepage, search engine, and new tab behavior are back to normal. Open your browser's extension list again to confirm nothing reinstalled itself. If your banking, email, or other sensitive accounts were accessed while infected, change those passwords immediately from a known-clean device or after you've verified your system is clean. Monitor your accounts for suspicious activity over the next few weeks as a precaution.
Prevention
- Download software only from official sources. Avoid third-party download sites like Softonic, download.com mirrors, and file-sharing platforms. Go directly to the developer's website. If you must use a third-party site, read reviews and verify the download is legitimate before running the installer.
- Always choose Custom or Advanced installation. Never click "Express Install" or "Recommended Installation" when installing free software. Custom installation lets you see—and decline—bundled offers for toolbars, search engines, browser modifications, and additional programs. Read every screen and uncheck optional offers.
- Keep your browser and plugins updated. Enable automatic updates for your web browser, and remove outdated plugins like Java, Flash Player (now deprecated), and Silverlight that are common exploit targets. Modern browsers handle most content natively without plugins, so you probably don't need them anymore.
- Install a reputable ad blocker. Extensions like uBlock Origin (not uBlock—there's a difference) block malicious ads and prevent accidental clicks on fake download buttons and deceptive update warnings. This single step prevents a significant percentage of PUP infections by eliminating the primary distribution mechanism.
- Be skeptical of update prompts. Legitimate software updates happen through the program itself or Windows Update—not through random websites telling you that Flash, Java, or your browser is outdated. If you see an update warning on a website, close it and manually check for updates through the official software.
- Review your installed programs monthly. Set a calendar reminder to check Control Panel → Programs and Features once a month. Uninstall anything you don't recognize or use. Hijackers and PUPs often sit dormant for weeks before activating, so regular audits help catch infections before they become entrenched.
- Use anti-malware with real-time protection. Windows Defender (Microsoft Defender) is adequate for basic protection, but combining it with Malwarebytes Premium adds a layer specifically designed to catch PUPs and browser hijackers. Real-time protection blocks threats before they install, which is far easier than removing them afterward.
- Create a limited user account for daily use. Configure your Windows system with an administrator account for system changes and a standard user account for everyday browsing and work. Many PUPs require administrator privileges to install persistence mechanisms, so running as a standard user limits the damage from accidental installations.
