Adware:TryMedia.A represents a family of advertising-supported software components historically bundled with trial versions of games and shareware applications. Unlike traditional adware that injects unwanted advertisements into your browsing experience, TryMedia.A primarily functions as a digital rights management (DRM) and analytics system for software trials—but its persistent background processes, data collection practices, and resistance to standard uninstallation have earned it classification as potentially unwanted software. Users typically discover this component months or years after installing a trial game they've long since forgotten about, when antivirus scans flag suspicious TryMedia registry entries or when performance monitoring tools reveal unexplained background processes consuming system resources.

How It Spreads
TryMedia.A gained its foothold during the mid-2000s shareware boom when game publishers and independent developers adopted TryMedia's platform as a DRM solution for trial versions of their software. The company positioned itself as a "try-before-you-buy" enabler, providing publishers with tools to enforce time-limited or feature-limited trials. When users downloaded trial games from legitimate sources—including major publishers' websites and established download portals like Download.com or Tucows—the TryMedia components installed silently alongside the game executable.
The problem emerged from TryMedia's aggressive persistence strategy and lack of transparency. Even after users uninstalled the trial game, TryMedia components remained active in the system, continuing to monitor for reinstallation attempts and reporting usage data. Many users never consented to this ongoing surveillance because the installation disclosures were buried in lengthy EULAs or presented during distraction-prone installation wizards.
Common distribution vectors included:
- Bundled game trials — PopCap games, Big Fish Games titles, and hundreds of casual gaming trials from 2005–2012 shipped with TryMedia DRM integrated into their installers
- Software download aggregators — Third-party download sites that hosted trial software often wrapped installers with additional TryMedia components without clearly disclosing the persistence behavior
- P2P and torrent networks — Pirated copies of trial software frequently retained the TryMedia components, which ironically continued phoning home even in unauthorized installations
- Shareware CD collections — Physical media compilations of trial software from the pre-broadband era often included multiple TryMedia-protected applications on a single disc
- Residual installations — Upgrading from older Windows versions sometimes carried forward TryMedia components in compatibility folders, reactivating them on the new system
What It Does On Your Machine
Once installed, TryMedia.A establishes multiple layers of persistence designed to survive standard uninstallation procedures. The system deploys a kernel-mode driver (typically named "ASPI32.SYS" or similar) that loads during Windows boot, giving it low-level access to monitor software installations and removals. This driver communicates with user-mode services that track which TryMedia-protected applications have been installed, how long they've been used, and whether the trial period has expired.
The most concerning behavior involves continuous system profiling. TryMedia components inventory your installed software, generate hardware fingerprints based on CPU identifiers and disk serial numbers, and maintain a database of every TryMedia-protected application you've ever tried—even ones uninstalled years ago. This database prevents users from extending trial periods by reinstalling, but it also creates a persistent surveillance apparatus that operates independently of any currently installed trial software.
Users typically notice TryMedia.A through performance monitoring tools that reveal CPU spikes from processes like "TryMediaTaskbarMonitor.exe" or "ActiveMARK.exe." Network monitoring may show periodic connections to TryMedia servers transmitting encrypted telemetry. On modern antivirus software, heuristic analysis flags the kernel driver and persistent services as exhibiting rootkit-like behavior due to their resistance to termination and concealed background operation.
The privacy implications extend beyond simple usage tracking. Because TryMedia components create persistent hardware fingerprints and maintain long-term installation histories, they effectively enable cross-application tracking—linking your identity across different trial software installations over years. While TryMedia Systems has claimed this data remains anonymized and serves only license enforcement purposes, the lack of user control over collection and retention raises legitimate privacy concerns that have led security vendors to classify these components as unwanted.
Manual Removal — Step by Step
Disconnect Network and Document Current State
Disable your Wi-Fi or unplug your Ethernet cable to prevent TryMedia components from receiving updates or transmitting additional telemetry during removal. Open Task Manager (Ctrl+Shift+Esc), switch to the Details tab, and take a screenshot showing any processes containing "TryMedia," "ActiveMARK," or "Trymedia" in their names or descriptions. This documentation helps verify complete removal later.
Boot to Safe Mode with Networking
Restart your computer and enter Safe Mode to prevent TryMedia services and drivers from loading. On Windows 10/11, hold Shift while clicking Restart, then navigate to Troubleshoot > Advanced Options > Startup Settings > Restart, and select option 5 for Safe Mode with Networking. This restricted environment prevents kernel-mode drivers from interfering with removal.
Stop TryMedia Services
Press Windows+R, type services.msc, and press Enter. Locate any service with "TryMedia" or "ActiveMARK" in the name, right-click it, select Properties, change Startup Type to "Disabled," then click Stop if the service is running. Repeat for all TryMedia-related services. This prevents them from restarting during the removal process.
Remove Registry Persistence Keys
Press Windows+R, type regedit, and press Enter. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and look for any entries referencing TryMedia executables—delete these entries. Then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\TryMedia Systems and delete the entire TryMedia Systems folder. Also check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services for TryMedia service entries and delete them.
Delete TryMedia Program Files
Open File Explorer and navigate to C:\Program Files\Common Files\ (and C:\Program Files (x86)\Common Files\ on 64-bit systems). Locate the "Trymedia Systems" folder, right-click it, select Delete, and confirm. If you receive an "access denied" error, take ownership of the folder first by right-clicking > Properties > Security > Advanced > Change owner to your user account.
Remove Kernel Driver Components
Navigate to C:\Windows\System32\drivers\ and search for files named "ASPI32.SYS" or similar TryMedia driver files (your antivirus scan results may have identified the specific filename). Delete these files. On some systems, you may need to use a specialized unlocker tool or boot from a Windows recovery environment to remove protected driver files.
Scan with Malwarebytes or Similar
Download and install Malwarebytes Free (from malwarebytes.com while still in Safe Mode with Networking), then run a full system scan. Malwarebytes specifically detects TryMedia components as PUP.Optional.TryMedia and can identify remnants that manual removal might miss. Quarantine or delete all identified threats, then restart as prompted.
Clean Scheduled Tasks
Press Windows+R, type taskschd.msc, and press Enter to open Task Scheduler. Expand Task Scheduler Library and review the task list for any entries related to TryMedia or ActiveMARK. Right-click these tasks, select Delete, and confirm. Some variants create tasks in subfolders under Task Scheduler Library, so check all branches.
Restart and Verify Removal
Restart your computer normally (not in Safe Mode). Once Windows loads, open Task Manager and confirm no TryMedia-related processes are running. Reconnect to your network and run a quick scan with your primary antivirus software to verify the threat no longer appears. Check the program installation list in Settings > Apps to confirm no TryMedia entries remain.
Review Installed Trial Software
Since TryMedia.A may reinstall if you still have affected trial games on your system, review your installed programs and uninstall any old trial software you no longer use. If you genuinely want to keep a TryMedia-protected trial, consider contacting the publisher to ask if a TryMedia-free version exists or if purchasing the full version removes the DRM components.
Prevention
- Research trial software sources thoroughly. Before downloading any trial application, search for "[software name] TryMedia" or "[software name] bundled adware" to see if other users have reported unwanted components. Prefer direct downloads from publishers' official websites over third-party download aggregators.
- Read installation wizards carefully. Don't click "Next" reflexively during software installation. Look for checkboxes offering to install "additional components," "license managers," or "DRM systems"—uncheck these when possible. Choose "Custom" installation over "Express" to see all components being installed.
- Monitor new installations with process monitoring. Use tools like Process Monitor (from Microsoft Sysinternals) to watch what files and registry entries installers create. If you see references to TryMedia during installation, cancel the process and seek alternative software.
- Keep antivirus definitions current. Modern antivirus software detects TryMedia.A variants as PUPs, but only if your definitions are up-to-date. Enable automatic updates for your security software and run weekly scheduled scans to catch unwanted installations early.
- Use virtualization for trial evaluations. If you frequently test trial software, consider using virtual machines (VirtualBox, VMware Workstation Player) for evaluations. This isolates trial software and any bundled components from your main system—you can simply delete the virtual machine when finished testing.
- Review installed programs monthly. Open Settings > Apps once per month and scroll through your installed program list looking for unfamiliar entries. Uninstall anything you don't recognize or no longer use, particularly utilities and "system optimizers" that often bundle unwanted components.
- Disable autoruns for unfamiliar software. Use Microsoft's Autoruns utility to review everything that launches at Windows startup. Disable entries you don't recognize, then research them before re-enabling. This prevents silent background processes from establishing persistence.
- Prefer subscription and portable software. Modern software distribution has largely moved away from trial-with-DRM models toward subscription services (Adobe Creative Cloud, Microsoft 365) and portable applications that don't require installation. These models rarely employ the aggressive persistence mechanisms seen in legacy trial software.
