Norman Sinowal Cleaner: Step-by-Step Security Removal Tutorial
The Sinowal Trojan (also known as Torpig or Mebroot) is a highly dangerous banking malware family that steals passwords, financial credentials, and digital certificates. It commonly infects the Master Boot Record (MBR) of Windows operating systems to gain kernel-level access before the OS even boots.
Because Sinowal injects code into legitimate system processes like explorer.exe, standard antivirus programs often fail to remove it while Windows is running. The Norman Malware Cleaner is a specialized, portable, on-demand security tool designed to bypass these roadblocks by running without installation, allowing it to purge active threats directly from Safe Mode.
Use this step-by-step tutorial to cleanly isolate and eliminate the Sinowal Trojan from an infected machine. Step 1: Download the Tool from a Clean Device
Sinowal actively monitors web traffic and can manipulate your browser sessions.
Use an uninfected backup computer to download the security software.
Download the executable from the official vendor or verified repositories like PCMag’s Norman Malware Cleaner Portal. Move the downloaded .exe file onto a clean USB flash drive. Step 2: Boot the Infected PC into Safe Mode
Booting into Safe Mode stops the Sinowal driver loader code from initializing during startup.
Turn off your infected PC and completely disconnect the internet cable (or turn off Wi-Fi) to stop data exfiltration.
Power on the PC and repeatedly tap the F8 key (for Windows 7 or older) until the Advanced Boot Options menu appears. For Windows ⁄11, hold the Shift key while clicking Restart in the power menu, then navigate to Troubleshoot > Advanced Options > Startup Settings > Restart, and select 4 or F4. Select Safe Mode from the interface. Sinowal banking trojan – Virus Bulletin
