KeyLogger.Ardamax is a commercial keystroke-logging software sold as a legitimate employee monitoring or parental control tool, but frequently repurposed by attackers for espionage and credential theft. Originally developed by Ardamax Software as "Ardamax Keylogger," this program records every key pressed on an infected system, captures screenshots at intervals, and logs application usage — then either stores the data locally or transmits it remotely to an attacker. While the vendor markets it as legal monitoring software, security researchers classify unauthorized installations as spyware because victims have no knowledge their activity is being recorded.
The software has been observed in targeted attacks against individuals, small businesses, and home users since the mid-2000s. Unlike modern malware that exploits zero-day vulnerabilities, KeyLogger.Ardamax typically arrives through social engineering: cracked software bundles, phishing email attachments, or physical installation by someone with temporary access to your machine. Once active, it runs silently in the background with no visible window, making detection difficult without anti-malware tools that recognize its signature patterns.

How It Spreads
Because KeyLogger.Ardamax is commercial software with a legitimate purchase channel, the infection vector differs significantly from self-replicating worms or exploit-kit malware. Attackers obtain licensed or cracked copies of the program, then deploy it through social engineering or opportunistic access rather than automated exploitation. The most common scenario involves an attacker who already has some level of access to the target system — either remotely through compromised credentials or physically by borrowing the machine under false pretenses.
Phishing campaigns remain a primary vector. Victims receive convincing emails with attachments named to resemble invoices, resumes, or shipping notifications. The attached executable is actually the keylogger installer, often packed with an icon that mimics Adobe PDF or Microsoft Office. Once the victim double-clicks the file, the installer runs silently with command-line switches that skip the GUI and enable stealth mode immediately. The victim sees nothing and assumes the document failed to open.
Other distribution methods include:
- Software bundles and cracks: Pirated games, cracked productivity software, and "free" license key generators from torrent sites frequently bundle the keylogger as a secondary payload. The user thinks they're installing Photoshop; they're also installing surveillance software configured to email logs to the bundler's address.
- Physical installation: A jealous partner, suspicious employer, or malicious acquaintance with temporary physical access installs the software directly. The commercial version includes a "stealth installation" feature specifically for this scenario, requiring only a few minutes of unsupervised access.
- Compromised remote desktop sessions: Attackers who gain RDP access through weak passwords or exposed Remote Desktop ports install the keylogger to maintain long-term surveillance even after the initial entry point is patched.
- USB drive autorun exploits: Older Windows systems with autorun enabled can execute the keylogger installer automatically when a malicious USB stick is inserted, though this vector has diminished since Windows 7 disabled autorun by default.
- Drive-by download campaigns: Less common for Ardamax specifically, but some affiliates have embedded the installer in malicious advertisements or compromised websites that prompt users to install a "required codec" or "security update."
What It Does On Your Machine
Once installed, KeyLogger.Ardamax begins its primary function: recording every keystroke on the system. The software intercepts keyboard input at a low level — either through Windows API hooks (SetWindowsHookEx) or a kernel-mode driver — capturing keys before they reach the target application. This means passwords typed into login forms, messages composed in email clients, search queries, chat conversations, and even data entered into encrypted applications are all logged in plaintext. The keystroke log includes timestamps and the name of the application or window title where each key was pressed, providing context for the attacker.
Beyond keystrokes, the software captures screenshots at configurable intervals (every 30 seconds, every minute, whenever specific keywords are typed, or when particular applications launch). These images are saved in compressed format and provide visual confirmation of user activity — especially valuable for capturing CAPTCHAs, on-screen keyboards used to bypass keyloggers, and graphical password systems. Clipboard data is also monitored: every time you copy a password from a password manager or copy sensitive text, that content is logged separately from keystrokes.
The collected data is stored in encrypted log files, typically in a hidden folder within %APPDATA% or %PROGRAMFILES%. The logs are periodically uploaded to the attacker through one of several methods: email (the keylogger includes an SMTP client that can send logs as encrypted attachments to Gmail, Outlook, or other providers), FTP upload to a remote server, or copying to a network share if the attacker is on the local network. The commercial version allows attackers to configure delivery frequency — every hour, daily, or when logs reach a certain size. Some variants also include a remote viewer application that lets the attacker monitor keystrokes in near real-time over the internet.
The software's stealth features make detection by casual users nearly impossible. The main executable runs with no visible window, no system tray icon, and no entry in the standard Windows Task Manager process list (older versions) or appears under a generic name like "svchost.exe" or "winlogon.exe" that blends in with legitimate Windows processes. The installation directory is often marked as hidden and system-protected. If the user discovers the program and attempts to uninstall it, recent versions require a password that only the installer knows — effectively locking the victim out of removing the spyware from their own machine.
Manual Removal — Step by Step
Disconnect from the Network Immediately
Unplug the Ethernet cable or disable Wi-Fi. If the keylogger is configured for real-time transmission, this prevents any credentials you type during cleanup from reaching the attacker. Leave the network disconnected through step 08.
Boot into Safe Mode with Networking
Restart the computer and press F8 (Windows 7) or Shift+F8 (Windows 8/10) during boot to access Advanced Boot Options. Select "Safe Mode with Networking." This loads only essential drivers and prevents most startup malware from launching, though kernel-mode variants may still load. On Windows 11, hold Shift while clicking Restart from the Start menu, then navigate to Troubleshoot > Advanced Options > Startup Settings > Restart, and select option 5.
Identify and Terminate the Keylogger Process
Open Task Manager (Ctrl+Shift+Esc) and click "Show processes from all users." Look for suspicious processes — common names include akl.exe, ardamax.exe, or generic names like svchost.exe running from unusual locations. Right-click the suspect process, select "Open file location," and note the path. If it's in Program Files\Ardamax or similar, that's your target. Right-click and "End Process Tree." If you cannot terminate it or it immediately restarts, proceed to step 04 before trying again.
Disable the Windows Service
Press Win+R, type services.msc, and press Enter. Scroll through the list looking for "Ardamax Keylogger Service" or any service with a suspicious name and description. Double-click it, change "Startup type" to "Disabled," click "Stop" to halt the service immediately, then click OK. This prevents the keylogger from restarting itself through the service mechanism.
Remove Registry Persistence Entries
Press Win+R, type regedit, and press Enter. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. Look for entries pointing to the installation folder you identified in step 03 (or any entry named "Ardamax"). Right-click each suspicious entry and delete it. Then navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services and delete the service key (usually named AKService or similar). Also check HKEY_CURRENT_USER\Software for an "Ardamax" key and delete the entire key if present.
Delete the Installation Directory and Logs
Open File Explorer and navigate to the installation folder (commonly C:\Program Files\Ardamax, C:\ProgramData\AKS, or %APPDATA%\AKS). Delete the entire folder. You may need to take ownership of the folder first: right-click the folder, select Properties > Security > Advanced, click "Change" next to the owner name, type "Administrators," click Check Names, then OK, and check "Replace owner on subcontainers and objects." Apply the change, then try deleting again. Also check the Startup folder at %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup for hidden shortcuts.
Scan with Malwarebytes or Similar Tool
Download Malwarebytes Free (from malwarebytes.com using a clean device, then transfer via USB if necessary). Install and run a full "Threat Scan." Malwarebytes specifically detects Ardamax variants and will catch remnants or secondary payloads you may have missed. Quarantine everything it flags related to keyloggers or spyware. If Malwarebytes is blocked from installing (some keylogger variants include anti-removal protection), try booting from a Windows rescue disk or bringing the machine to our shop.
Check for and Remove Kernel-Mode Drivers
Open an elevated Command Prompt (right-click Start, select "Command Prompt (Admin)" or "Windows PowerShell (Admin)"). Type sc query type=driver | findstr /i "ardamax ak" to search for driver services with suspicious names. If any appear, note the service name and run sc stop [servicename] then sc delete [servicename]. Then navigate to C:\Windows\System32\drivers and look for files like aksflt.sys or similar. Delete any driver files associated with the keylogger (you may need to boot from a rescue disk if Windows File Protection blocks deletion).
Reset Browser Settings and Clear Saved Passwords
If you use Chrome, Firefox, or Edge, the keylogger has likely captured any passwords you typed or that were autofilled. Open each browser's settings, reset to defaults (this removes extensions the keylogger may have installed for additional tracking), and clear all saved passwords. You will need to re-enter credentials at each site after you've changed the underlying passwords in step 10.
Change All Critical Passwords from a Clean Device
Using a different computer or smartphone that was never compromised, immediately change passwords for: email accounts (especially the primary recovery email), bank and financial accounts, PayPal or payment processors, work VPN or remote access, social media, password manager master password if applicable, and any sites where you store payment methods. Assume every password typed on the infected machine during the infection period was captured.
Reboot Normally and Verify Removal
Restart the computer without entering Safe Mode. Reconnect to your network. Open Task Manager and verify no suspicious processes are running. Check the Services list again to confirm the keylogger service hasn't reappeared. Run Malwarebytes one more time to ensure nothing reactivated. Monitor your Task Manager for the next few days during normal use; if you see unusual CPU spikes or network activity when idle, the infection may have deeper rootkit components requiring professional removal.
Prevention
- Maintain physical security of devices. Use Windows login passwords or BitLocker encryption so that brief physical access by others doesn't grant them the ability to install software. Don't leave laptops unattended in public spaces or unlocked in shared offices.
- Avoid pirated software and cracks. The majority of Ardamax infections among home users come bundled with "free" versions of paid software downloaded from torrents or warez sites. If you can't afford software, look for legitimate free alternatives (GIMP instead of Photoshop, LibreOffice instead of Microsoft Office) rather than cracked versions.
- Enable User Account Control (UAC) and don't click through warnings. When Windows asks "Do you want to allow this app to make changes?" actually read what program is requesting elevation. Keylogger installers need administrator rights to install their service and kernel drivers; UAC is your warning that something significant is about to happen.
- Use email filtering and attachment vigilance. Don't open unsolicited email attachments even if they appear to come from known senders (their account may be compromised). Hover over attachment names to see the true file extension — "Invoice.pdf.exe" is an executable pretending to be a PDF. Enable Gmail's or Outlook's advanced phishing protection features.
- Keep anti-malware software active and updated. Windows Defender (built into Windows 10/11) or a third-party solution like Malwarebytes Premium will catch known keylogger signatures during installation. Enable real-time protection and don't disable it "just for a minute" to install something suspicious.
- Lock your computer when stepping away. Press Win+L every time you leave your desk. This simple habit prevents physical installation scenarios where someone sneaks software onto your machine during a bathroom break or lunch.
- Secure remote access tools. If you use Remote Desktop, TeamViewer, or similar tools, require strong unique passwords and two-factor authentication. Disable remote access entirely when not actively using it. Attackers frequently scan the internet for open RDP ports with weak passwords.
- Regularly review startup programs and installed applications. Once a month, open Task Manager > Startup tab and Control Panel > Programs and Features. Look for anything unfamiliar or that you don't remember installing. Keyloggers often hide for months before users notice, but they'll appear in these lists unless specifically designed to avoid them.
When Computer Repair Roswell removes malware from your system, we guarantee it stays removed. If the same infection returns within 90 days and you haven't installed new software or visited risky sites, we'll re-clean the machine at no additional charge. We also provide a written report detailing what we found, what we removed, and what accounts you should secure — so you have a complete picture of the compromise and how to prevent recurrence.
Bring It In
Keylogger infections are particularly unsettling because of the privacy implications. Every password, every private message, every financial transaction you conducted while infected may now be in an attacker's possession. Manual removal following the steps above will eliminate the software, but it won't answer questions like: how long was it there? What data was actually transmitted? Did the attacker install additional backdoors? At Computer Repair Roswell, we perform forensic analysis to determine the infection timeline, identify exfiltrated data based on log remnants, and verify complete removal including any secondary payloads. We'll also help you prioritize which accounts to secure first based on what the keylogger captured.
