Imgtrx.com is a browser redirect and potentially unwanted program (PUP) that hijacks web browsers to force users through sponsored search engines and advertising networks. Unlike traditional malware that encrypts files or steals credentials directly, this threat monetizes your browsing activity by injecting advertisements, redirecting search queries, and collecting behavioral data for third-party advertising platforms. Victims typically notice unexpected homepage changes, search results routed through unfamiliar domains, and an increase in pop-up advertisements even on normally clean websites.
While Imgtrx.com itself doesn't typically encrypt files or install ransomware, it creates security vulnerabilities by exposing browsers to additional malicious sites and diminishes system performance through constant background network activity. The redirect behavior degrades the browsing experience and poses privacy risks through aggressive data collection practices common to adware operations.

How It Spreads
Imgtrx.com rarely arrives alone or through direct user choice. The primary distribution method involves software bundling, where legitimate-seeming freeware applications include the hijacker as an "optional" component buried in installation screens. Users who click through installer prompts using "Express" or "Typical" settings inadvertently authorize the browser modifications. These bundled installers frequently disguise the hijacker as a "search enhancement tool" or "web optimization utility" to appear beneficial rather than intrusive.
Fake update notifications represent another major infection vector. Users encounter convincing pop-ups claiming their Flash Player, browser, or video codec needs updating. Clicking these fraudulent update prompts downloads an installer package that deploys Imgtrx.com alongside whatever legitimate-looking software was promised. These fake updates appear on compromised websites, torrent sites, and free streaming platforms where users have lowered security expectations.
Malicious browser extensions provide a third entry point. The hijacker may appear in official browser stores under misleading names like "Fast Search," "Quick Converter," or "Video Downloader," with fabricated positive reviews to establish false credibility. Once installed, these extensions request broad permissions to "read and change all your data on websites you visit," which grants them the access needed to inject redirects and advertisements.
- Bundled freeware installers from download sites offering video converters, PDF tools, or system utilities
- Fake software update prompts for Flash Player, Java, or media codecs on questionable websites
- Malicious browser extensions masquerading as useful productivity or entertainment tools
- Compromised websites serving drive-by download scripts targeting browser vulnerabilities
- Email attachments containing installers disguised as legitimate software or documents (less common for this threat family)
- Pirated software packages and cracked application bundles from torrent sites
What It Does On Your Machine
Once established, Imgtrx.com modifies browser configurations to intercept and redirect user navigation. The hijacker changes your default search engine to route queries through imgtrx.com or associated domains, which then forward you to sponsored search engines like Yahoo or Bing—not because Microsoft or Yahoo created the hijacker, but because the operators earn referral revenue for the redirected traffic. Your homepage and new tab page settings change to display advertiser content or additional search portals controlled by the threat actors.
The redirect behavior follows a specific pattern designed to obscure the monetization chain. When you perform a search, the query goes first to imgtrx.com, which logs the search terms and your browser fingerprint. The request then bounces through one or more intermediate domains before landing on the final search engine or advertising page. This multi-hop redirection makes the traffic source harder to trace and allows the operators to insert tracking parameters that credit them for your activity. Users report searches taking noticeably longer due to these additional network hops.
Advertisement injection represents the other primary behavior. The hijacker inserts additional ads into legitimate websites you visit, displaying banners and pop-ups that the site operators never authorized. These injected ads often promote questionable services—fake tech support, rogue antivirus products, or additional PUPs. The hijacker can also replace legitimate ads on websites with its own, redirecting revenue from content creators to the threat operators. Browser performance degrades as the injection scripts consume CPU cycles and memory.
Data collection runs continuously in the background. Imgtrx.com tracks your search queries, visited URLs, clicked links, and time spent on pages to build an advertising profile. This information gets transmitted to remote servers and potentially sold to data brokers or advertising networks. While this behavioral tracking doesn't typically capture passwords or credit card numbers directly, it creates a detailed profile of your interests, habits, and online behavior that poses privacy concerns.
Manual Removal — Step by Step
Disconnect from the Internet
Unplug your ethernet cable or disable Wi-Fi to prevent Imgtrx.com from downloading additional components or transmitting collected data. This also stops the redirect behavior temporarily so you can work more effectively. Keep your device offline until you've completed all removal steps and verified the infection is gone.
Document Current Browser Settings
Before making changes, write down what your homepage and search engine settings currently show. Open each installed browser (Chrome, Firefox, Edge) and check Settings → Search Engine and Settings → On Startup. Take screenshots if helpful. This documentation helps you identify what needs restoring and confirms when removal succeeds.
Remove Suspicious Browser Extensions
Open each browser's extension/add-on manager and carefully review installed items. Remove anything you don't recognize, didn't intentionally install, or that has suspicious names related to "search," "helper," "optimizer," or random character strings. In Chrome, go to Menu → Extensions; in Firefox, Menu → Add-ons; in Edge, Menu → Extensions. Don't just disable them—fully uninstall to prevent re-activation.
Check Programs and Features for PUPs
Open Control Panel → Programs and Features (or Settings → Apps on Windows 10/11). Sort by installation date and look for unfamiliar programs installed around when the redirect behavior started. Uninstall anything suspicious, especially items with names like "Web Companion," "Search Manager," "Browser Assistant," or publisher names you don't recognize. Be thorough—bundled installers often deploy multiple components.
Remove Scheduled Tasks and Startup Items
Press Win+R, type "taskschd.msc," and examine the Task Scheduler Library for suspicious tasks—especially those running executables from %LOCALAPPDATA% or %APPDATA% folders with random names. Delete suspicious tasks. Then open Task Manager (Ctrl+Shift+Esc), check the Startup tab, and disable any unfamiliar startup entries. These persistence mechanisms cause re-infection after restart if not removed.
Clean Registry Run Keys
Press Win+R, type "regedit," and navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. Look for entries pointing to executables in %LOCALAPPDATA% with random folder names or anything matching the programs you uninstalled. Right-click suspicious entries and delete them. Backup your registry first if you're uncomfortable with this step—incorrect changes can cause system issues.
Delete Associated Files and Folders
Open File Explorer and navigate to C:\Users\[YourName]\AppData\Local and \AppData\Roaming. Look for folders with random GUID-like names ({8F3D2A1B...}) or names matching uninstalled programs. Delete these folders entirely. Also check your browser profile folders for leftover extension directories. Show hidden files if needed (View → Options → Show hidden files).
Reset Browser Settings
In each affected browser, perform a settings reset to clear hijacked configurations. Chrome: Settings → Reset settings → Restore to defaults. Firefox: Help → More troubleshooting information → Refresh Firefox. Edge: Settings → Reset settings → Restore to defaults. This removes unauthorized changes but preserves bookmarks and passwords. You'll need to reconfigure your preferred homepage and search engine afterward.
Run Malwarebytes or Similar Scanner
Reconnect to the internet and download Malwarebytes Free (from malwarebytes.com—verify the URL). Install and run a full threat scan. The scanner catches persistence mechanisms and associated PUPs that manual removal might miss. Follow prompts to quarantine detected items. Restart if prompted, then run a second scan to confirm everything's clean.
Verify and Monitor
Restart your computer normally and test your browsers. Confirm that your chosen homepage loads, searches go through your preferred engine without redirects, and no unexpected ads appear. Monitor for 24-48 hours—if redirect behavior returns, residual components remain. Check your browser extension list daily for a week to catch any auto-reinstalling items that indicate deeper infection.
Prevention
- Always use Custom/Advanced installation options when installing free software. Read each screen carefully and uncheck pre-selected offers for toolbars, browser helpers, or search utilities. The legitimate program you want shouldn't require bundled extras.
- Download software only from official publisher websites or verified app stores. Avoid third-party download sites like Softonic, Download.com, or CNET Downloads that repackage installers with PUPs. When searching for software, go directly to the developer's site rather than clicking sponsored search results.
- Keep browsers and operating systems updated with the latest security patches. Enable automatic updates for Windows, macOS, Chrome, Firefox, and Edge. Current versions close vulnerabilities that drive-by downloads exploit.
- Install a reputable ad blocker like uBlock Origin to prevent malicious advertisements from displaying. Many hijacker infections start with clicking fake update ads—blocking them at the browser level eliminates this vector. Configure the blocker to filter third-party trackers as well.
- Review browser extensions quarterly and remove anything you don't actively use. Browser stores occasionally host malicious extensions that pass initial review but update to malicious code later. Fewer extensions mean less attack surface.
- Never click "Allow" on unexpected permission prompts—especially notifications from unfamiliar websites. If a video site claims you need to enable notifications to watch content, close the tab. Legitimate services don't require notification permissions to function.
- Run periodic scans with anti-malware tools even when everything seems normal. Schedule monthly full-system scans with Malwarebytes or Windows Defender to catch low-profile infections before they establish persistence.
- Educate everyone who uses your computer about these risks. Browser hijackers often arrive through children downloading game mods or adults installing free PDF converters. Brief household members on recognizing suspicious installers and fake updates.
