InPorn.com is a browser hijacker that forcibly redirects users to adult content websites and advertising portals, often arriving bundled with free software downloads or through deceptive pop-up ads. Once installed, this potentially unwanted program (PUP) modifies browser settings without permission, changing your homepage, default search engine, and new tab page to redirect through its own servers. While not technically a virus in the traditional sense, InPorn.com exhibits malicious behavior by persistently reinstalling itself, tracking your browsing activity, and exposing you to questionable websites that may host more serious threats.

How It Spreads
InPorn.com rarely arrives as a standalone installation. The most common infection vector is software bundling, where the hijacker piggybacks on legitimate-looking free programs downloaded from third-party software repositories. During installation, most users click through the setup wizard using "Express" or "Recommended" settings, unknowingly agreeing to install additional offers. The hijacker components are pre-selected by default, buried in fine print or obscured behind misleading checkboxes that require you to opt-out rather than opt-in.
Fake software updates represent another significant distribution channel. Users encounter pop-ups claiming their Flash Player, Java, or media codec is out of date. The update prompt looks convincing, complete with legitimate-looking logos and urgent language. Clicking "Update Now" downloads an installer that contains the hijacker alongside—or instead of—any actual software update. These fake update pages appear on compromised websites or through malicious advertising networks.
Common distribution methods include:
- Bundled freeware/shareware — Download managers, PDF converters, video players, and codec packs from sites like Softonic, Download.com, or torrent trackers
- Fake Flash/Java update notifications — Pop-ups on streaming or file-sharing sites claiming your player is outdated
- Malicious advertisements — Banner ads and pop-unders on adult content sites, streaming platforms, or piracy-related pages
- Email attachments disguised as documents — Especially in spam campaigns targeting users with phony invoice or shipping notifications
- Torrent files and cracks — Software piracy tools and keygens frequently contain bundled PUPs
- Compromised browser extensions — Legitimate-looking productivity tools or ad blockers from unofficial sources
What It Does On Your Machine
Once installed, InPorn.com immediately targets your web browsers. It modifies critical browser settings to ensure every search query and new tab passes through its redirection infrastructure. Your homepage, which might have been Google or a custom page, suddenly points to an unfamiliar search engine—often branded with generic names and loaded with sponsored content. When you type a search query into your address bar, instead of going to your preferred search engine, the hijacker intercepts the request, routes it through its servers to collect the data, then redirects you through several advertising pages before eventually showing search results (often from a legitimate engine like Bing or Yahoo, making the redirection seem less obvious).
The behavior is financially motivated. Each redirect and ad impression generates revenue for the hijacker's operators through pay-per-click advertising networks. You might click a result expecting to visit a news site and instead land on a page full of sensational advertisements, fake download buttons, or adult content. The hijacker also injects additional advertisements into legitimate websites you visit, overlaying banners and pop-unders that weren't placed by the site's owners.
Beyond annoyance, InPorn.com collects browsing data. It tracks which sites you visit, what you search for, how long you spend on pages, and which links you click. This information gets packaged and sold to advertising networks or used to create targeted ad profiles. While the hijacker itself doesn't typically steal passwords or banking credentials, the data harvesting represents a genuine privacy violation. The tracking occurs even in "private" or "incognito" browsing modes if the hijacker has installed system-level components.
The hijacker establishes persistence through multiple mechanisms. It creates scheduled tasks that run hourly or at system startup, ensuring that even if you manually reset your browser settings, they'll be changed back within minutes. Registry modifications tell Windows to launch helper processes automatically. Browser extensions get installed with administrative permissions, making them difficult to remove through normal means. Some variants monitor for attempts to change browser settings and immediately revert any modifications, creating a frustrating loop for users who try to fix the problem manually.
Manual Removal — Step by Step
Disconnect from the Network
Unplug your Ethernet cable or turn off Wi-Fi before proceeding. This prevents the hijacker from downloading additional components during removal and stops any ongoing data transmission to its command servers.
Boot into Safe Mode with Networking
Restart your computer and repeatedly press F8 during boot (or hold Shift while clicking Restart on Windows 10/11, then navigate to Troubleshoot → Advanced Options → Startup Settings → Restart → press 5 for Safe Mode with Networking). Safe Mode prevents the hijacker's auto-start components from loading, making removal significantly easier.
Uninstall Suspicious Programs
Open Control Panel → Programs and Features (or Settings → Apps on Windows 10/11). Sort by install date and look for unfamiliar programs installed around the time redirects began. Common names include generic terms like "Web Helper," "SearchAssist," "BrowserUpdate," or random character strings. Uninstall anything you didn't intentionally install, even if the publisher looks legitimate.
Remove Browser Extensions
Open each installed browser and navigate to the extensions/add-ons page (chrome://extensions/ in Chrome, about:addons in Firefox, edge://extensions/ in Edge). Remove any extensions you don't recognize, especially those installed recently without your knowledge. Pay special attention to extensions with vague names or those requesting excessive permissions like "Read and change all your data on websites you visit."
Delete Scheduled Tasks
Press Win+R, type taskschd.msc, and press Enter. In Task Scheduler, expand Task Scheduler Library and review the tasks list. Look for entries with random names, those pointing to executables in AppData folders, or tasks running hourly/at startup that you didn't create. Right-click suspicious tasks and select Delete. The hijacker often creates tasks with innocuous names like "SystemUpdate" or random GUIDs.
Clean Registry Auto-Start Entries
Press Win+R, type regedit, and press Enter. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Look for entries pointing to suspicious executables in AppData or Program Files folders. Right-click and delete any entries associated with programs you removed in step 3. Be careful to only delete entries you're certain about—these keys also contain legitimate startup programs.
Delete Hijacker Files
Open File Explorer and enable viewing hidden files (View → Show → Hidden items). Navigate to C:\Users\[YourUsername]\AppData\Local and AppData\Roaming. Look for folders with random GUID names (long strings of numbers and letters) or folder names matching the programs you uninstalled. Delete these entire folders. Also check C:\Program Files and C:\Program Files (x86) for leftover folders.
Reset Browser Settings
In each browser, manually reset your homepage and search engine. In Chrome: Settings → On startup (set your preference) → Search engine (choose Google/Bing/DuckDuckGo). In Firefox: Options → Home (set homepage) → Search (choose default). For thorough cleaning, consider using each browser's reset function: Chrome Settings → Reset and clean up → Restore settings to original defaults; Firefox Help → More Troubleshooting Information → Refresh Firefox.
Run a Reputable Anti-Malware Scanner
Download and install Malwarebytes (the free version works fine for this purpose) while still in Safe Mode. Run a full system scan. Malwarebytes specifically targets PUPs and browser hijackers that traditional antivirus might miss. Quarantine or delete everything it finds. For additional verification, run a second scan with AdwCleaner (also from Malwarebytes) which specializes in adware removal.
Restart and Verify
Restart your computer normally (not in Safe Mode). Reconnect to your network and open your browser. Verify that your homepage is correct, searches go through your chosen engine, and you're not seeing unexpected redirects. Test for 24-48 hours to ensure the hijacker doesn't reinstall itself. If redirects return, you likely missed a persistence mechanism—at that point, professional removal is the most efficient option.
Prevention
- Download software only from official sources. Get programs directly from the developer's website, never from third-party download sites. File-sharing platforms and software repositories routinely bundle PUPs with legitimate installers.
- Always choose "Custom" or "Advanced" installation. Never click through installers using Express/Recommended settings. Read each screen carefully and uncheck any offers for additional software, browser toolbars, or homepage changes. Legitimate software doesn't hide additional offers—if an installer makes declining difficult, that's a red flag.
- Keep your actual software updated. Enable automatic updates for Windows, your browsers, and plugins like Adobe Reader. When legitimate update prompts appear, close the pop-up and update through the program's own interface or official website. Never click "Update Now" buttons in browser pop-ups.
- Use a reputable ad blocker. Extensions like uBlock Origin prevent many malicious advertisements from loading in the first place. This blocks a primary infection vector while also improving browsing speed and privacy.
- Install browser extensions only from official stores. Use Chrome Web Store for Chrome extensions, Firefox Add-ons for Firefox. Even then, review the permissions requested and check recent user reviews for complaints about suspicious behavior.
- Maintain real-time antivirus protection. While Windows Defender provides baseline protection, it sometimes misses PUPs categorized as "not-a-virus." Consider supplementing with Malwarebytes Premium for real-time PUP blocking, or at minimum run occasional scans with the free version.
- Be skeptical of urgency. Messages claiming "Your Flash Player is critically out of date" or "Your PC is infected—scan now" are almost always deceptive. Legitimate software doesn't use scare tactics. When in doubt, close the browser tab and verify through official channels.
- Review installed programs monthly. Set a calendar reminder to check Programs and Features for unfamiliar entries. Catching a PUP early, before it establishes deep persistence, makes removal exponentially easier.
Bring It In
Browser hijackers like InPorn.com are frustrating precisely because they spread themselves across multiple system components. You might successfully remove the browser extension only to have a scheduled task reinstall it an hour later. Or you might clean the registry but miss the helper application that rewrites those entries at next boot. The manual process works, but it requires patience, technical comfort, and time most people would rather spend elsewhere.
