Trojan & Adware removal procedures

Generic Trojan / Adware Removal Procedures
(2 different procedures you can try for malware removal)
By: David Lipman

Procedure #1

  1. Download the following four items (links will open a new browser window)...

    McAfee Stinger
    Trend Sysclean Package

    Latest Trend Virus Pattern Files. (example;*)
    (*The file name is simply an example name of the file and you'll find the filename posted at TrendMicro will have a higher number than 285. Each time TrendMicro produces new Pattern Files the number in the file name will be incremented accordingly.)

    Ad-Aware SE (free personal edition)

  2. Create a new directory.

    • On drive "C:\"
      (e.g., "c:\New Folder")
    • or the desktop
      (e.g., "C:\Documents and Settings\username\Desktop\New Folder")

    Place SYSCLEAN.COM (the Trend Sysclean Package referenced above) into the new directory you created. Extract the latest Trend Virus Pattern Files (Example: lpt$vpn.285 and WHATSNEW.TXT) from the zip file you downloaded above into the same new directory you created. The Trend Pattern File contained in the ZIP file must be placed in the same directory as SYSCLEAN.COM!

    Important: The TrendMicro Pattern file is updated reguarly. Aywhere from once per day to a few times in a day. Always make sure you have the latest version of SYSCLEAN.COM and the Pattern File before you scan your platform. The McAfee Stinger Internet worm and Trojan removal tool is upgraded periodically. Always make sure you have the latest version of McAfee Stinger utility before you scan your platform.

  3. Install and Update Ad-Aware with the latest definitions.
  4. If you are using WinME or WinXP, disable System Restore.
  5. Reboot your PC into Safe Mode [F8 key during boot process].
    How to Boot Into Safe Mode:

    Windows XP
    How to perform a clean boot in Windows XP
  6. Using McAfee Stinger, the Trend Sysclean utility and Ad-Aware, perform a Full Scan of your platform and clean and/or delete any infectors and/or parasites found (a few cycles may be needed).
  7. Restart your PC and perform a "final" Full Scan of your platform using McAfee Stinger, the Trend Sysclean utility and Ad-Aware.
  8. If you are using WinME or WinXP,Re-enable System Restore and re-apply any System Restore preferences (e.g. HD space to use suggested 400 ~ 600MB).
  9. Reboot your PC.
  10. If you are using WinME or WinXP, create a new Restore point

End of Procedure #1

Procedure #2

Download MULTI_AV.EXE from the URL --

It is a self-extracting ZIP file that contains the Kixtart Script Interpreter { - Kixtart is CareWare } 4 batch files, 6 Kixtart scripts, one Link (.LNK) file, a PDF instruction file and two utilities; UNZIP.EXE and WGET.EXE. It will simplify the process of using; Sophos, Trend, Kaspersky and McAfee Anti Virus Command Line Scanners to remove viruses, Trojans and various other malware.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor’s web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you can download the files and perform a scan in Normal Mode. Once you have downloaded the files needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key during boot] and re-run the menu again and choose which scanner you want to run in Safe Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help file.
To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close
Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your FireWall to allow it to download the needed AV vendor related files.
