InfinityTV by AccEngage.net is a browser extension and potentially unwanted program (PUP) that positions itself as a streaming TV service but functions primarily as adware. While not technically malware in the traditional sense of file-encrypting ransomware or banking trojans, this software exhibits deceptive installation practices, aggressive advertising behavior, and privacy-invasive tracking that warrants its classification as unwanted. Users typically discover InfinityTV installed alongside free software bundles, often without their explicit consent, and soon find their browsing experience degraded by intrusive ads, browser redirects, and performance slowdowns.
The AccEngage.net network has been associated with multiple adware variants over the years, and InfinityTV represents one iteration of browser extensions designed to monetize user web traffic through affiliate marketing and ad injection. What makes these programs particularly problematic is their tendency to modify browser settings, intercept search queries, and collect browsing data—all behaviors that compromise both system performance and user privacy. Understanding how this PUP operates and how to remove it completely is essential for restoring your computer to normal functionality.

How It Spreads
InfinityTV rarely arrives as a standalone download that users intentionally seek out. Instead, it relies almost exclusively on deceptive distribution tactics designed to bypass user awareness. The most common infection vector is software bundling, where the InfinityTV installer is packaged with legitimate free software—video converters, PDF readers, download managers, and similar utilities. During installation, the bundle presents the adware as an "optional offer" or "recommended component," often pre-checked or worded to make declining the offer confusing. Users who click through installation wizards using "Express" or "Recommended" settings inadvertently agree to install InfinityTV alongside their intended software.
Beyond traditional software bundles, InfinityTV leverages other social engineering tactics to achieve installation. Compromised or malicious websites display fake update notifications claiming the user needs to install a "video codec," "player update," or "streaming component" to view content. These fake prompts mimic legitimate browser or media player notifications, exploiting user trust to initiate the download. Some variants have also appeared through malvertising campaigns, where clicking on infected advertisements triggers an automatic download or redirect to an installation page.
Distribution methods for InfinityTV include:
- Freeware and shareware bundles — Hidden in installation wizards for popular free utilities, particularly those downloaded from third-party hosting sites rather than official developer websites
- Fake codec and player update prompts — Messages claiming a "codec is missing" or "your Flash Player is outdated" on suspicious streaming or video sites
- Torrent and warez sites — Bundled with cracked software, key generators, or pirated media downloads
- Malvertising and compromised ads — Infected advertisements on legitimate sites that trigger drive-by downloads or redirect to installer pages
- Pay-per-install affiliate networks — Distributed by affiliates who earn commissions for each installation, incentivizing aggressive bundling tactics
- Fake download buttons — Deceptive "Download" buttons on file-hosting sites that install adware instead of the intended file
What It Does On Your Machine
Once installed, InfinityTV establishes persistence through multiple mechanisms to ensure it continues running even if users attempt simple removal through browser settings. The primary component is a browser extension that injects itself into Chrome, Firefox, Edge, or Internet Explorer. This extension modifies the browser's behavior to display additional advertisements on websites you visit, redirect search queries through affiliate networks, and track your browsing activity. You'll notice ads appearing in places they shouldn't—banner ads inserted into search results, pop-ups on sites that normally don't have them, in-text advertising where random words become hyperlinks, and video ads that play before content loads.
The adware typically alters your browser's default search engine and new tab page, redirecting searches through intermediate domains before delivering results. This allows the operators to collect data on what you're searching for and inject sponsored results at the top of search pages. Your homepage may also change without permission, often to a branded search portal or content aggregation page designed to generate advertising revenue. These modifications persist because InfinityTV often installs system-level components that reapply the changes even after you manually reset your browser settings.
Performance degradation becomes noticeable as the extension consumes system resources to inject ads, load tracking scripts, and communicate with remote advertising servers. Pages load more slowly because each page view triggers multiple additional connections to ad networks. Your browser may become unresponsive or crash more frequently, particularly when opening multiple tabs. Network bandwidth is consumed by the constant traffic to tracking and advertising domains, which can be particularly problematic for users with metered or limited connections.
The privacy implications are significant. InfinityTV collects browsing history, search queries, clicked links, and potentially personally identifiable information depending on the websites you visit while the extension is active. This data is typically used for targeted advertising but may be shared with third-party advertising networks or sold to data brokers. The extension operates with broad permissions that allow it to read and modify content on every website you visit, creating a comprehensive profile of your online behavior.
Manual Removal — Step by Step
Disconnect and Document
Disconnect your computer from the internet (unplug Ethernet or disable Wi-Fi) to prevent the adware from receiving updates or communicating with its control servers during removal. Take note of any suspicious programs in your installed applications list (Control Panel → Programs and Features or Settings → Apps) and write down unusual browser behavior you've experienced—this helps verify complete removal later.
Uninstall InfinityTV Program
Open Control Panel → Programs and Features (or Settings → Apps on Windows 10/11) and look for any entries named "InfinityTV," "AccEngage," or recently installed programs you don't recognize. Sort by installation date to identify recent additions. Select the suspicious program and click Uninstall. During uninstallation, watch for any prompts asking if you want to keep settings or components—decline all such offers to ensure complete removal.
Remove Browser Extensions
Open each affected browser and navigate to the extensions/add-ons management page (chrome://extensions/ for Chrome, about:addons for Firefox, edge://extensions/ for Edge). Look for any InfinityTV extensions or any unfamiliar extensions you didn't intentionally install. Remove them completely—don't just disable them. Check the extension installation date to identify recently added items. Restart the browser after removal to ensure changes take effect.
Reset Browser Settings
In each browser's settings, reset your homepage, search engine, and new tab page to your preferred choices. In Chrome, check Settings → Search engine and Settings → On startup. In Firefox, check Options → Home and Options → Search. Additionally, clear all browsing data including cookies, cache, and site data from the time period when InfinityTV was active—this removes tracking cookies and cached adware content.
Check Scheduled Tasks
Open Task Scheduler (search for it in the Start menu) and review the Task Scheduler Library for any tasks related to InfinityTV, AccEngage, or tasks with random names that have been recently created. Look at the "Actions" tab of suspicious tasks to see what executable they run. Delete any tasks that reference the adware's installation folders or have descriptions mentioning updates or browser launches for unfamiliar programs.
Clean Registry Persistence
Press Windows+R, type "regedit," and press Enter to open Registry Editor. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and look for any values referencing InfinityTV, AccEngage, or executable paths in your AppData folders that you don't recognize. Delete those values. Also check HKEY_CURRENT_USER\Software\ for any InfinityTV or AccEngage keys and delete them. Be cautious in the registry—only delete items you're confident are related to the adware.
Delete File System Remnants
Open File Explorer and navigate to C:\Users\[YourUsername]\AppData\Local\ and C:\Users\[YourUsername]\AppData\Roaming\. Look for folders named InfinityTV, AccEngage, or recently created folders with random names or GUIDs. Delete these entire folders. You may need to enable viewing hidden files (View → Show → Hidden items) to see the AppData folder. Empty the Recycle Bin when finished to permanently remove these files.
Run Malwarebytes Scan
Download and install Malwarebytes Free from the official Malwarebytes website (reconnect to internet for this step). Update the definitions to the latest version, then run a full "Threat Scan." Malwarebytes is particularly effective at detecting adware remnants and registry entries that manual removal might miss. Quarantine and remove all detected items. This acts as verification that you've successfully removed all components.
Verify Browser Behavior
After reconnecting to the internet, open your browsers and visit several websites you use regularly. Check that you're not seeing unexpected ads, that searches go to your chosen search engine, and that your homepage and new tab page are correct. Visit a few sites you had problems with before to confirm the ads are gone. If issues persist, check browser extensions again—some adware attempts to reinstall itself or leaves behind components that reactivate.
Change Passwords (If Necessary)
If you entered passwords on any websites while InfinityTV was installed and active, consider changing those passwords as a precaution. While InfinityTV is primarily adware rather than a credential stealer, it had broad permissions to view page content. Change passwords for sensitive accounts (banking, email, social media) from a clean device or after confirming complete removal. Enable two-factor authentication where available for additional security.
Prevention
- Download software only from official sources. Avoid third-party download sites that bundle additional software. When you need free software, go directly to the developer's official website rather than using download repositories, even well-known ones that may insert their own installers.
- Always choose Custom/Advanced installation. Never click through installation wizards using Express or Recommended settings. Custom installation reveals bundled software offers that you can decline. Read each screen carefully and uncheck any pre-selected optional components or offers for additional software.
- Keep browsers and extensions minimal. Only install browser extensions you actively need from official browser stores (Chrome Web Store, Firefox Add-ons). Review installed extensions monthly and remove any you no longer use or don't remember installing. Fewer extensions mean fewer potential security vulnerabilities.
- Maintain updated security software. Run a reputable antivirus with real-time protection and keep it updated. Windows Defender (built into Windows 10/11) provides solid baseline protection if kept current. Supplement with periodic scans using Malwarebytes Free to catch PUPs and adware that traditional antivirus might classify as "low risk."
- Enable click-to-play for plugins. Configure browsers to require your permission before running Flash, Java, or other plugins. This prevents many drive-by download attempts and fake update prompts that rely on automatic plugin execution. Most modern browsers have deprecated these plugins, but it's still good practice for older systems.
- Be skeptical of update prompts on websites. Legitimate software updates come through the software itself or Windows Update, not through browser pop-ups on random websites. If a site claims you need to update Flash, a codec, or Java to view content, close the page and verify the update through official channels if genuinely needed.
- Use an ad blocker with anti-tracking. Extensions like uBlock Origin block most malicious advertisements and reduce exposure to malvertising campaigns that distribute adware. Configure it to block third-party tracking scripts as well, which reduces the effectiveness of the tracking that adware performs even if installed.
- Create a standard user account for daily use. Don't operate Windows with an administrator account for everyday browsing and work. A standard user account requires administrator approval for software installation, creating a barrier against silent adware installation through drive-by downloads or bundled installers.
Bring It In
While the manual removal steps above work for straightforward InfinityTV infections, adware often comes bundled with additional unwanted programs that all need to be addressed. What appears to be a single browser extension issue might actually involve multiple PUPs working together, browser policy modifications that prevent settings changes, or rootkit-level components that resist standard removal. If you've attempted removal and are still experiencing redirects, excessive ads, or performance problems—or if you're simply not comfortable working in the Windows registry and Task Scheduler—professional removal ensures complete elimination without risk of damaging system files.
