In some situation especially when anti-virus program has cleaned, healed, disinfected or removed a worm, trojan horse or virus from computer, there may be error happening whenever users try to open or access the drive by double clicking on the disk drive icon in Explorer or My Computer window to try to enter the drive’s folder. The problem or symptom happens in hard disk drive, portable hard disk drive or USB flash drive, and Windows will prompt a dialog box with the following message:
windows script Host
Can not find script file autorun.vbs.
Sometimes you will be asked to debug the VBScript with error code of 800A041F - Unexpected ‘Next’.
Choose the program you want to use to open this file with:
In this case, the “Always use the selected program to open this kind of file” option is grayed out.
The symptom occurs because when autorun.vbs is created by trojan horse or virus. The virus normally loads autorun.inf file to root folder of all hard drive or USB drive, and then execute autorun.bat file which contains script to apply and merge autorun.reg into the registry, with possible change to the following registry key to ensure that virus is loaded when system starts:
Finally, autorun.bat will call wscript.exe to run autorun.vbs.
When antivirus or security software detected the autorun.vbs file as infected, the file will be deleted or removed or quarantined. However, other files (autorun.*） and registry value still referring to autorun.vbs, and this document no longer exists, hence the error when users double click to open a drive folder.
To correct and solve this error, follow this steps:
Run Task Manager (Ctrl-Alt-Del or right click on Taskbar)
Stop wscript.exe process if available by highlighting the process name and clicking End Process.
Then terminate explorer.exe process.
In Task Manager, click on File -> New Task (Run…).
Type “cmd” (without quotes) into the Open text box and click OK.
Type the following command one by one followed by hitting Enter key: del c:\autorun.* /f /s /q /a
del d:\autorun.* /f /s /q /a
del e:\autorun.* /f /s /q /a
c, d, e each represents drive letters on Windows system. If there are more drives or partitions available, continue to command by altering to other drive letter. Note that you must also clean the autorun files from USB fllash drive or portable hard disk as the external drive may also be infected.
In Task Manager, click on File -> New Task (Run…).
Type “regedit” (without quotes) into the Open text box and click OK.
Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Check if the value name and value data for the key is correct (the value data of userint.exe include the path which may be different than C drive, which is also valid, note also the comma which is also needed): “Userinit”=”C:\WINDOWS\system32\userinit.exe,”
If the value is incorrent, modify it to the valid value data
What is a portable program ?
A portable program is a piece of software that you can carry around with you on a portable device and use on any other computer. It can be your email program, your browser, system recovery tools or even an operating system. The coolest part about it, is that all of your data and settings are always stored on a thumbdrive so when you unplug the device, none of your personal data is left behind.

That’s mainly it… In case you’re looking for something that wasn’t mentioned above, there are a couple of resources you may want to check out.
Norton AntiVirus Clients or Symantec AntiVirus Clients especially Corporate Edition Clients can be installed as managed network setup type by a Symantec AntiVirus Server. When a Symantec AntiVirus Client is managed, it will prompt for password when uninstalling client via local computer Control Panel Add or Remove Program applet. If you don’t know or forget the password, then the client is not able to uninstall or remove. And the SAV client uninstall password won’t work with server group password too, as if you enter that password, you will receive an invalid password message.
The client uninstallation password is different from the server group password, and it can be set by the administrator through the Symantec System Center for the client that is managed. If the client uninstallation password has not been set or changed specifically, it will still be the default password. Thus, first thing to try in order to successfully uninstall a Symantec Client Security program is by using the default password for the uninstalling clients, which is symantec.
In the cases where Symantec AntiVirus server has been taken down and no longer exist, or the client computer has no access to company network, or the default client uninstall password does not work, the following hack will enable you to remove Symantec Antivirus without using a password:
Open Registry Editor (regedit).
Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\VirusProtect6\CurrentVersion\Administrator Only\Security\
Change the value for useVPuninstallpassword key from 1 to 0.
Exit Registry Editor and now you can uninstall Symantec AntiVirus Client.
The trick should work on most version of Symantec AntiVirus client or Norton AntiVirus Client, including version 7, 8, 9 or 10.
