Start-Up Applications - All

Last update :- 13th November, 2003
3738 items listed

Introduction

This page presents a searchable, comprehensive list of the programs you may find that run when you switch on your PC as typically identified by MSCONFIG or the registry "Run" keys - and whether you need them.

Close Program/Task Manager

This is NOT a list of tasks/processes taken from Task Manager or the Close Program window (CTRL+ALT+DEL) but a list of startup applications, although you will find some of them listed via this method. Pressing CTRL+ALT+DEL identifies programs that are currently running - not necessarily at startup. For a list of tasks/processes you should try WinTasks 4 Standard/Professional from LIUtilities or the list at AnswersThatWork

Operating System Differences

A number of entries are repeated due to the way that different operating systems display startup items. For example, WinMe lists "POPROXY.EXE" as "Norton eMail Protect" whereas WinXP lists it as "Poproxy"

Random startup entry/filename viruses

There are viruses and other pests that can add any number of different entries to the startups. They make additional entries under the registry key HKLM\Software\Microsoft\Windows\CurrentVersion\ Run and RunOnce keys, allowing them to run at startup:

(1) PE_BISTRO - adds XXXX = "C:\WINDOWS\XXXX.EXE" - where XXXX is the randomly chosen filename of the dropped file
(2) MAGISTR.A - adds <Virus Name> = "<Path of Virus>\<Virus Name>.EXE"
(3) BUGBEAR - adds <random string> = %system%\<random filename>.EXE. %system% is a variable - by default this is C:\Windows\System (Win9x/Me), C:\Winnt\System32 (WinNT/2K), or C:\Windows\System32 (WinXP). The worm locates the System folder and copies itself to that location
(4) OPTIXPRO.11 - adds <Registry entry> = "<Path of Virus>\<Filename>"
(5) Lop.com homepage hijacker - creates multiple and random startup entries
(6) FreeScratchAndWin - creates multiple and random startup entries as it includes LOP above
(7) nCase (or n-Case) parasite - creates multiple and random startup entries
(8) LORAC - adds "<four random characters>" = "%System%\abcdef.exe" - where abcdef is the volume number of the infected hard drive
(9) MOSUCK - random name and filename in C:\Windows or C:\Winnt
(10) DEBORMS.D - adds one of a number of valid Name/Startup Item entries but points to the path of the worm file dropped
(11) GIBE.C - random name and filename in C:\Windows or C:\Winnt
(12) SWEN.A - random name and filename
(13) ZOMBAM.B - random name and filename
(14) WANADO or REUR - name and filename as XXXXXXXX where X can be any random hexadecimal (0-9, A-F) number
(15) SINCOM - random name and filename in C:\Windows or C:\Winnt with "Run:Auto" appended to the command/data column entry
(16) SOBER - adds <random string> = %system%\<random filename.exe>
(17) BRANCOS.C - adds win_<4 random characters><4 random numbers 0-9> (<4 random characters><4 random numbers 0-9>.exe)
(18) IRC.BOT.B - random name and filename
(19) COREFLOO-C - <random filename> = rundll32 %SYSTEM% <random filename>.dll,Init 1

NAccessRamp Monitor01ARMon32a.exeFrom a visitor "Just wanted to provide you with some info on Access Ramp software installed with Verizon DSL accounts in those areas that use the Winpoet PPPoE software. The Access Ramp TSRs are installed as part of IP Insight software (can't remember the software maker). You can decline to install IP Insight during Winpoet setup, or go into Add/Remove programs uninstall IP Insight by hand if it's already installed. It really doesn't do a darn thing for you. It was intended to help DSL techs monitor QoS, but the backend part was never implemented (at least as of earlier this year). This will not affect the user's ability or inability to access their DSL service."
NAccessRampLAN01ARUpld32.exeVersion of the above for LAN connections - a history uploader. The key in turning it off is a file named ARUCfg32.exe. This file (ARUCfg32.exe) does not show up in the startup process. If you have this file, you can execute it and remove all the monitoring activities it does. Removing all the checks in all the boxes (both tabs) still calls ARUpld32.exe to start when you start the dial up. You can block it from sending info if you have Zone Alarm installed. Renaming the extension of ARUCfg32.exe to ARUCfg32.exe1 works. The ARUpld32.exe is not loaded when launching the dial up client.
