What kind of malware is Evil Extractor?
Evil Extractor (EvilExtractor) is a tool utilized for stealing sensitive data from users in Europe and the U.S. It is marketed by Kodex, a company that charges $59 per month for its use. Despite being advertised as a legitimate tool, Evil Extractor is predominantly promoted on hacking forums to attract threat actors.
The tool features seven attack modules, including ransomware, credential extraction, and bypassing Windows Defender.
More about Evil Extractor
Evil Extractor includes date and time checking, anti-sandbox, anti-VM, anti-scanner, FTP server setting, data theft, stolen data upload, log clearing, and ransomware modules.
Upon downloading the Evil Extractor data-stealing module, three additional Python components are installed. The first module can extract cookies from Google Chrome, Microsoft Edge, Opera, and Firefox while also collecting browsing history and saved passwords from an extensive range of other programs.
The second module functions as a keylogger, saving the victim's keyboard inputs to a local folder for exfiltration. The third module, a webcam extractor, can surreptitiously activate the webcam, record video or images, and upload them to the attacker's rented FTP server provided by Kodex.
Also, the malware exfiltrates a wide range of document and media file types from both the Desktop and Downloads folders, captures screenshots, and sends all the stolen data to the malware's operators.
The ransomware module, if triggered, downloads a supplementary file from Kodex's website, which is a straightforward yet potent file-locking mechanism that leverages 7-Zip to generate a password-protected archive comprising the victim's files, rendering them inaccessible without the password.
The ransomware strain delivered via Evil Extractor is dubbed Kodex.

Possible damage
Victims of Evil Extractor may experience various damages, including but not limited to, theft of their sensitive data such as browsing history, saved passwords, and personal documents, ransomware attacks that encrypt their files and demand payment for decryption.
Also, they may encounter unauthorized access to their webcam resulting in the capture of private images or videos, and the compromise of their system's security and stability due to the malware's bypassing of Windows Defender and other security measures.
Thus, it is strongly recommended to remove Evil Extractor from infected systems as soon as possible.
How did Evil Extractor infiltrate my computer?
Evil Extractor is commonly distributed via phishing emails that appear to be account confirmation requests and contain a gzip-compressed executable attachment disguised as a legitimate PDF or Dropbox file but is, in fact, a Python executable program.
When the recipient opens the file, a PyInstaller file is initiated, triggering a .NET loader that leverages a base64-encoded PowerShell script to launch an Evil Extractor executable.
During the initial launch, the malware verifies the system time and hostname to detect whether it is operating within a virtual environment or an analysis sandbox, in which case it terminates to avoid detection.
How to avoid installation of malware?
Always verify email source and content before clicking links or downloading files (attachments). Keep your operating system and software up-to-date with the latest security patches and updates. Install and regularly update anti-malware software to help detect and remove malicious programs before they can cause damage.
Do not trust ads and links on shady web pages. Download programs (and files) from reliable sources such as official pages and stores. Avoid downloading from other sources (e.g., third-party downloaders, P2P networks, dubious sites, etc.).
If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Most trojan infections can be removed by running a full system scan with Combo Cleaner. The full manual procedure below is for cases where automatic removal failed, where you want to verify a scan caught everything, or where the threat has multiple persistence points.
Disconnect from the network
Unplug your Ethernet cable and turn off Wi-Fi. If you're on a laptop, the airplane-mode key works fastest.
Many trojans exfiltrate data - saved browser passwords, banking sessions, screenshots - and accept remote commands. Cutting the network stops both immediately. Keep it disconnected until Phase 4.
Boot into Safe Mode with Networking
Safe Mode loads a minimal set of drivers and stops most malware from auto-running. "With Networking" lets you download tools - re-enable Wi-Fi only after you've booted in.
Open . Click Restart now next to Advanced startup.
Your computer will restart into the "Choose an option" menu. Click . After the second reboot, press 5 or F5.
Click the Windows logo, hold Shift, click the Power icon and choose Restart. In the Choose an option screen, click . Press F5.
Windows 8
Go to the Start Screen, type Advanced, select Settings → Advanced startup options → Restart now → Troubleshoot → Advanced options → Startup settings → Restart → F5.
Note: Windows 8 reached end-of-life in January 2023 - running on it puts you at much higher risk of reinfection.
Windows 7
Click Start → Shut Down → Restart → OK. As the system boots, press F8 repeatedly until the Windows Advanced Options menu appears, then choose Safe Mode with Networking.
Note: Windows 7 reached end-of-life in January 2020 - running on it puts you at much higher risk of reinfection.
Inspect running processes with Process Explorer
Download Process Explorer from Microsoft Sysinternals. Run it as Administrator. Click and .
Sort by "Verified Signer." Anything unsigned running from %AppData%, %LocalAppData%, %Temp%, or %ProgramData% is suspicious. Right-click → Properties to see the full image path. Right-click → "Search Online" to look up unfamiliar process names.
Task Manager hides full file paths, doesn't show digital signatures, and groups processes in ways that make malware easy to miss. Process Explorer is the same tool Microsoft engineers use.
Map every persistence point with Autoruns
Download Autoruns. Right-click Autoruns.exe and choose Run as administrator - without elevation, Autoruns can't inspect protected registry hives.
In the menu, open and , then click Refresh.
Modern trojans don't just live in startup. Walk through these tabs and look for unsigned or unfamiliar entries:
- Logon - classic Run/RunOnce keys
- Scheduled Tasks - frequent hiding spot, especially tasks with PowerShell, MSHTA, or rundll32 actions
- Services - unsigned services in non-Microsoft folders
- WMI - Event Subscriptions are a stealthy persistence mechanism (MITRE T1546.003)
- Image Hijacks - Image File Execution Options "Debugger" abuse
- AppInit - DLLs loaded into every GUI process
- Browser plug-ins - unsigned add-ons across all installed browsers
Right-click any suspicious entry → "Jump to Image" to see the actual file. Right-click → "Search Online" opens VirusTotal for the file hash. Don't delete yet - just write down the file paths and entry names. We'll remove them after the scans.
Check the hosts file and DNS settings
Trojans often redirect bank, antivirus, and update domains to attacker-controlled servers by editing the hosts file or DNS settings.
Hosts file: Open Notepad as Administrator and open C:\Windows\System32\drivers\etc\hosts. Legitimate entries are commented with #. Any uncommented IP-to-domain mapping is suspicious - especially redirects for microsoft.com, windowsupdate, or your bank.
DNS settings: Open Command Prompt as Administrator and run ipconfig /all. Confirm your DNS servers point to your ISP, your router, or a known public resolver (Cloudflare 1.1.1.1, Google 8.8.8.8). Then open and verify both DNS and DNS over HTTPS (DoH) settings haven't been hijacked.
A clean PC with hijacked DNS is still a compromised PC. You'll think you're at chase.com and you'll be at the attacker's clone.
No single antivirus catches everything. The order below is intentional: offline scan first (catches rootkits before Windows fully loads), then on-demand scanners on the running system, then manual cleanup of anything they missed.
Run Microsoft Defender Offline
Reboot to normal Windows. Open . Select Microsoft Defender Antivirus (offline scan) and click Scan now. Your computer will restart into a stripped-down environment and scan before the full operating system loads.
Rootkits and bootkits hide from any scanner running on the same Windows session that's already infected. A pre-boot offline scan sees the disk before the malware can hide itself.
VB100 certified. Includes anti-trojan, registry/persistence scanning, anti-spyware in one pass. The 7-day free trial is available.
Download Combo CleanerRun Combo Cleaner full system scan
Install Combo Cleaner and run a full system scan (not the quick scan). Let it complete fully, review the detected threats, and apply the recommended actions. Combo Cleaner will quarantine known trojans and registry persistence.
Run Microsoft Safety Scanner as a second-opinion scan
Download Microsoft Safety Scanner (MSERT.exe), Microsoft's free on-demand tool. The binary expires every 10 days, which means every download has the latest signatures. Run a full scan after Combo Cleaner to catch anything one engine alone might miss.
Different scanning engines catch different threats. Running an additional Microsoft scan after Combo Cleaner is the single most underused verification step in malware removal.
Manually remove anything still listed in Autoruns
Reopen Autoruns. Anything you flagged in Step 4 that's still present hasn't been caught by the automated scans. For each remaining suspicious entry: right-click → Delete in Autoruns (this removes the persistence registration), then navigate to the file path and delete the actual file. Empty the Recycle Bin.
Some malware files reappear after deletion because something else on the system recreates them. If you delete a file and it returns within minutes, you have a remaining persistence point that Autoruns didn't show - usually a service or scheduled task running under SYSTEM. Re-run the scans from Steps 6-8 or proceed to a clean install (see end of guide).
Reset browsers and clear notification permissions
Trojans and adware frequently hijack browsers - change the default search engine, install rogue extensions, or grant themselves notification permissions to keep displaying scam pop-ups even after the malware is gone.
- Chrome: visit
chrome://settings/resetand click "Restore settings to their original defaults." Then visitchrome://settings/content/notificationsand remove any unfamiliar sites. - Edge: visit
edge://settings/reset. Then checkedge://settings/content/notifications. - Firefox: open
about:supportand click Refresh Firefox (Firefox uses "Refresh," not "Reset"). Then check Settings → Privacy & Security → Permissions → Notifications.
Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.
Re-enable Defender, Tamper Protection, and update everything
Many trojans disable security software. Open and confirm Real-time protection, Cloud-delivered protection, and Tamper Protection are all turned on. Tamper Protection prevents malware from disabling Defender silently.
Then run Windows Update () and update your browsers and applications. The infection vector that let the trojan in originally usually involves outdated software.
Change passwords from a clean device
If the trojan was an info-stealer (Lumma, RedLine, Vidar, and similar are extremely common), assume every password saved in your browser is compromised. Change them from a different, known-clean device - your phone is fine if it's not infected.
Recommended order:
- Primary email first - it's the recovery hub for everything else
- Banking and financial accounts
- Password manager master password (if you use one)
- Social media, shopping, and remaining accounts
Where available, enable phishing-resistant multi-factor authentication (passkeys / FIDO2 hardware keys / authenticator apps) - SMS-based MFA is bypassable by sophisticated attackers.
Verify the clean and monitor for 7 days
Reconnect to the network and run one final full scan with Combo Cleaner. Open Task Manager (Ctrl + Shift + Esc) and switch to the Startup apps tab - confirm nothing suspicious has reappeared.
Over the next 7 days, watch for symptom recurrence: unexpected high CPU usage, unknown processes returning, browser redirects, or pop-ups. If anything returns, you missed a persistence point and the procedure needs to be repeated - or you may have a deeper compromise that requires a clean install.
When to clean install Windows instead
Manual removal isn't always the right answer. Reinstalling Windows from scratch is the only way to be 100% certain when:
- The malware reappears after every removal attempt
- A bootkit or UEFI rootkit was detected (this class of threat sits below the operating system and survives a normal Windows reinstall)
- A confirmed credential-theft trojan ran with administrator privileges (Lumma, RedLine, Vidar) - the system likely has multiple unknown payloads
- The PC is used for online banking, business email, or anything where partial doubt isn't acceptable
A clean install is a 30-60 minute process: Windows 11 reinstall via . Back up documents to external storage first, scan the backup with Combo Cleaner before restoring it, and reinstall applications fresh - never restore them from a backup of the infected system.
Important: Manual removal requires advanced computer skills. If you're not confident identifying system files from malicious files, run an automated scan with Combo Cleaner and Windows Defender and stop there - that path catches the vast majority of consumer trojans without the risk of breaking Windows by deleting the wrong file.
