Amadey is a straightforward loader-style botnet that emerged in late 2018 and quickly became a mainstay on Russian-language cybercrime forums, where it sells for around $500. Unlike flashy ransomware that announces itself immediately, Amadey operates quietly in the background, inventorying your system, fingerprinting your antivirus software, and awaiting instructions from a remote command-and-control server. Its core purpose is to serve as a delivery platform for additional malware—ranging from information stealers and banking trojans to ransomware payloads—making it a versatile tool for criminals who want flexibility in what they deploy to compromised machines.
If you suspect Amadey is running on your computer, you're dealing with an active infection that is likely phoning home regularly and may already be dropping secondary malware. The infection won't advertise itself with pop-ups or lock screens, but you may notice unexplained CPU spikes, network activity when you're not browsing, or new processes with randomized names appearing in Task Manager. This guide explains what Amadey does, how it spreads, and how to remove it manually—though professional removal is strongly recommended for infections involving loader malware, since secondary payloads often persist even after the initial dropper is gone.

How It Spreads
Amadey is distributed through a variety of vectors that exploit both technical vulnerabilities and human mistakes. The malware is typically packaged by affiliates who purchase access to the botnet infrastructure and then deploy it using whatever distribution channel yields the best infection rate. You won't see Amadey advertised in phishing emails by name, but you will encounter it bundled inside trojaned installers, attached to malicious documents, or delivered by exploit kits that target unpatched browsers.
One of the most common delivery methods is software bundling. Cracked software, key generators, and pirated game installers hosted on file-sharing sites or torrents frequently carry Amadey as a silent payload. Users think they're installing a productivity app or game patch, but the installer quietly drops the botnet loader alongside the legitimate files. Similarly, fake update prompts—such as bogus Flash Player or codec installers served by malicious ad networks—have been used to push Amadey to unsuspecting visitors.
Known distribution channels include:
- Malicious email attachments: Office documents with macro downloaders that fetch Amadey from a remote server
- Trojanized installers: Cracked software, keygens, and pirated media bundled with the loader
- Exploit kits: Drive-by downloads from compromised websites targeting outdated browser plugins
- Malvertising campaigns: Fake update prompts and misleading download buttons on ad-supported sites
- Secondary infections: Dropped by earlier-stage malware like Emotet, TrickBot, or SmokeLoader
What It Does On Your Machine
Once Amadey executes, it immediately begins profiling your system. The malware collects detailed information about your Windows version, installed antivirus software, system language, hardware configuration, and network environment. This fingerprint is packaged and transmitted to the attacker's command-and-control server via HTTP POST requests, often to hardcoded domains or IP addresses that change frequently as infrastructure is cycled. The server responds with instructions—either to sit idle and beacon periodically, or to download and execute a specific "task," which is simply another piece of malware tailored to the attacker's current objective.
Amadey's modular design means it doesn't need to carry heavy functionality itself. Instead, it acts as a beachhead, pulling down info-stealers to harvest browser credentials, cryptocurrency wallet files, and saved passwords; banking trojans to intercept financial transactions; or ransomware to encrypt files for extortion. In some campaigns, infected machines are simply added to a botnet pool and rented out to other criminals for spam distribution or DDoS attacks. The loader runs persistently, meaning it will survive reboots and continue checking in with the C2 server until removed.
From a technical standpoint, Amadey is relatively unsophisticated but effective. It uses basic persistence techniques like registry Run keys or scheduled tasks to ensure it launches every time Windows starts. Strings and configuration data are often obfuscated to evade static analysis, but the malware does not employ advanced rootkit techniques or kernel-mode drivers. Behavioral indicators include outbound HTTP traffic to unusual domains, new executables appearing in temporary folders, and registry modifications under current user or local machine hives.
Because Amadey functions as a loader, you may not notice it directly. Instead, you'll see symptoms caused by the payloads it delivers—browser redirects, missing files, cryptocurrency miners maxing out your CPU, or unauthorized purchases if a banking trojan is involved. By the time these symptoms appear, the infection is often multilayered, with Amadey continuing to operate in the background while secondary malware does the visible damage.
Manual Removal — Step by Step
Boot into Safe Mode with Networking
Restart your computer and press F8 (or Shift+F8 on newer systems) during boot to access Advanced Boot Options. Select Safe Mode with Networking. This prevents Amadey from loading its full set of startup hooks, though some variants may still execute if they've hooked deeper startup sequences. Safe Mode gives you a cleaner environment to work in and limits the malware's ability to interfere with removal.
Identify Suspicious Processes in Task Manager
Press Ctrl+Shift+Esc to open Task Manager. Look under the Processes tab for unfamiliar executables, especially those with random alphanumeric names running from AppData\Local\Temp or AppData\Roaming. Note the file path (right-click the process, select Open File Location), then terminate the process. Be cautious—Amadey may spawn multiple child processes or restart quickly if you miss a component.
Check Startup Registry 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 with random names pointing to executables in AppData or Temp folders. Delete any suspicious entries. Amadey typically uses a short random string for the value name to blend in with legitimate startup programs.
Inspect Scheduled Tasks
Open Task Scheduler (taskschd.msc via Run dialog). Expand Task Scheduler Library and look for tasks with random names or descriptions that reference unfamiliar executables. Select the task, check the Actions tab to see what it runs, then delete any tasks associated with Amadey's file paths. Some variants create tasks that run at logon or at regular intervals to re-download payloads.
Delete the Malware Files
Navigate to the file paths you noted in Step 2. Typical locations are C:\Users\[Username]\AppData\Local\Temp\ and C:\Users\[Username]\AppData\Roaming\[random_folder]\. Delete the entire folder if possible, or at minimum the executable files. Use Shift+Delete to bypass the Recycle Bin. If Windows says the file is in use, you may need to boot into Safe Mode again or use a file-unlocking utility.
Scan with Multiple Antivirus Tools
Amadey often delivers secondary malware, so even after removing the loader itself, additional threats may remain. Run full scans with at least two reputable on-demand scanners—such as Malwarebytes, HitmanPro, or ESET Online Scanner—in addition to your primary antivirus. Focus on "deep" or "custom" scans that examine all drives and memory. Quarantine or delete everything flagged.
Check Browser Extensions and Settings
If Amadey delivered an info-stealer or adware payload, your browsers may have been compromised. Open each browser (Chrome, Firefox, Edge), navigate to the extensions/add-ons page, and remove anything you don't recognize. Reset your homepage and search engine settings to defaults. Consider clearing all saved passwords and re-entering them after confirming the machine is clean, since many Amadey-distributed stealers exfiltrate browser credential stores.
Monitor for Residual Activity
Restart in normal mode and observe the system for 24–48 hours. Use Process Explorer or Task Manager to watch for suspicious processes reappearing. Check your network activity (Resource Monitor → Network tab) for unexpected outbound connections. If you see executables respawning from AppData or unusual HTTP POST traffic, the infection is not fully removed—either a secondary payload persists or Amadey's persistence mechanism was missed.
Change All Passwords from a Clean Device
If your machine was compromised by Amadey, assume any credentials entered or stored on that system have been harvested. From a separate, known-clean device (smartphone, tablet, another computer), change passwords for email, banking, social media, and any other sensitive accounts. Enable two-factor authentication wherever possible. Do not change passwords from the infected machine until you're confident it's fully disinfected.
Consider a Full System Restore or Reinstall
If you cannot confirm complete removal—or if Amadey delivered unknown payloads that evaded your scans—the safest option is to back up personal files (after scanning them offline) and perform a clean Windows reinstall. Loader malware like Amadey can drop multiple persistence points and rootkit-like components that are difficult to remove piecemeal. A fresh install ensures you're starting from a known-good state.
Prevention
- Avoid pirated software and crack sites. The majority of Amadey infections originate from trojanized installers downloaded from file-sharing platforms, torrent trackers, and warez forums. Stick to official vendor websites and legitimate app stores for all software downloads.
- Enable real-time antivirus protection and keep it updated. Modern AV solutions detect most Amadey variants by signature or heuristic behavior. Ensure your antivirus is active, set to update definitions daily, and configured to scan downloads automatically before execution.
- Patch Windows and third-party applications promptly. Exploit kits that deliver Amadey target known vulnerabilities in browsers, Flash, Java, and other plugins. Enable automatic updates for Windows and uninstall or disable unnecessary browser plugins that serve as attack vectors.
- Use a standard (non-admin) account for daily work. Running as a limited user reduces the impact of malware execution. Amadey can still infect your user profile, but it won't be able to write to system-wide registry hives or critical Windows directories without triggering a UAC prompt.
- Be skeptical of email attachments and links. Amadey's initial loaders are often delivered via macro-enabled Office documents or PDF files with embedded scripts. Do not enable macros in documents from unknown senders, and scrutinize any unexpected attachments—even from known contacts, as their accounts may be compromised.
- Deploy DNS-level filtering or ad blocking. Use a DNS service (like Quad9 or Cloudflare's malware-filtering resolver) or browser-based ad blocker to reduce exposure to malvertising campaigns that push fake software updates and trojanized downloads. Many Amadey infections begin with a misleading download button on a sketchy streaming or file-hosting site.
- Regularly back up important files offline. Keep versioned backups on an external drive or cloud service that's not continuously mounted. If Amadey delivers ransomware, you'll be able to restore your data without paying the ransom. Ensure backups are not accessible from the infected machine to prevent malware from encrypting them as well.
- Monitor network traffic and system behavior. Homeowners and small businesses can use free tools like GlassWire or Windows Resource Monitor to spot unusual outbound connections. Frequent HTTP POST requests to unknown domains or executables beaconing at regular intervals are red flags for botnet activity like Amadey.
Bring It In
Manual removal of Amadey is possible for experienced users, but it's time-consuming and error-prone—especially when secondary payloads are involved. Loader malware creates a multilayered infection that requires careful forensic work to fully eradicate. Miss one scheduled task, one registry key, or one hidden executable, and the botnet reinstalls itself the next time you reboot. Worse, if Amadey delivered an info-stealer or banking trojan, you may have a ticking clock on your financial accounts and saved credentials, with no clear indication of what was exfiltrated.
