Hi guys hope you are well and can help.
Guys, I have the following requirement and would love to create a vbscript to do this.

1) Delete the following registry keys (if they exist).
HKEY_LOCAL_MACHINE\Software\McAfee\HIP
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EnterceptAgent
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FireHook
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\firelm01
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FirePM
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FireTDI

2) Delete the following folder
C:\Program Files\McAfee\Host Intrusion Prevention

3) Delete the following files
C:\Windows\System32\FireCL.dll
C:\Windows\System32\FireCNL.dll
C:\Windows\System32\FireCore.dll
C:\Windows\System32\FireEpo.dll
C:\Windows\System32\FireNHC.dll
C:\Windows\System32\FireSCV.dll

The end result would be something like the below as a hta file:

--------------------------------------------- delreg.hta

Please enter a computer name: _______________

<Run>

On running, the outcome of each step would be seen eg.

Running Step 1).......... completed.
Running Step 2).......... completed.
Running Step 3).......... completed.

Script finished.

Any help greatly appreciated.

HIi astroviper,
Thanks so much for your help.
astro,
Does your script cater for registry keys that do not exist, or if the folder on disk does not exist?

The "On Error Resume Next" part at the top means that it will fail silently if the key or the folder/file doesn't exist. It was easier for me at the time... If you need it I could try putting in some feedback as to whether or not the operations were successful.

Error checking isn't normally something I both with, other than letting the script host handling it. I just remembered there are some objects that a HTA can't access but a dedicated vbscript file can. I'm not sure if that was causing a problem but to be sure, here's a vbscript that outputs a html file instead. Also has some basic error checking.

On Error Resume Next

strComputer = InputBox("Enter computer:" & VbCrLf & ". for localhost")

strFile = strComputer & "Report.html"

Set objFSO = CreateObject("Scripting.FileSystemObject")
 

strOutput = "<html><head><title>" & strComputer & "'s Results</title></head><body>"
 

DeleteKey strComputer, "Software\McAfee\HIP"

CheckError

DeleteKey strComputer, "SYSTEM\CurrentControlSet\Services\EnterceptAgent"

CheckError

DeleteKey strComputer, "SYSTEM\CurrentControlSet\Services\FireHook"

CheckError

DeleteKey strComputer, "SYSTEM\CurrentControlSet\Services\firelm01"

CheckError

DeleteKey strComputer, "SYSTEM\CurrentControlSet\Services\FirePM"

CheckError

DeleteKey strComputer, "SYSTEM\CurrentControlSet\Services\FireTDI"

CheckError
 

strOutput = strOutput & "Deleting C:\Program Files\McAfee\Host Intrusion Prevention" & _

    " on " & strComputer & "..."

objFSO.DeleteFolder "\\" & strComputer & "\c$\Program Files\McAfee\Host Intrusion Prevention", True

CheckError
 

DeleteFile strComputer, "Windows\System32\FireCL.dll"

CheckError

DeleteFile strComputer, "Windows\System32\FireCNL.dll"

CheckError

DeleteFile strComputer, "Windows\System32\FireCore.dll"

CheckError

DeleteFile strComputer, "Windows\System32\FireEpo.dll"

CheckError

DeleteFile strComputer, "Windows\System32\FireNHC.dll"

CheckError

DeleteFile strComputer, "Windows\System32\FireSCV.dll"

CheckError
 

strOutput = strOutput & "Script Complete.<br>"
 

strOutput = strOutput & "</body></html>"
 

Set objOutput = objFSO.CreateTextFile(strFile)

objOutput.Write strOutput

objOutput.Close
 
 
 

    Sub DeleteFile(strComputer, strPath)

		strOutput = strOutput & "Deleting C:\" & strPath & _

			" on " & strComputer & "..."

		objFSO.DeleteFile "\\" & strComputer & "\c$\" & strPath, True

	End Sub
 

	Sub DeleteKey(strComputer, strKeyPath)

		On Error Resume Next 
 

		Const HKEY_CURRENT_USER = &H80000001 

		Const HKEY_LOCAL_MACHINE = &H80000002
 

		Set objRegistry = GetObject("winmgmts:\\" & _

			strComputer & "\root\default:StdRegProv") 
 

		strOutput = strOutput & "Deleting " & strKeyPath & _

			" on " & strComputer & "..."

		DeleteSubkeys HKEY_LOCAL_MACHINE, strKeypath 
 

	End Sub
 

	Sub DeleteSubkeys(HKEY_CURRENT_USER, strKeyPath) 

			Set objRegistry = GetObject("winmgmts:\\" & _

			strComputer & "\root\default:StdRegProv")

            objRegistry.EnumKey HKEY_CURRENT_USER, strKeyPath, arrSubkeys 
 

		If IsArray(arrSubkeys) Then 

			For Each strSubkey In arrSubkeys 

				DeleteSubkeys HKEY_CURRENT_USER, strKeyPath & "\" & strSubkey 

			Next 

		End If 
 

		objRegistry.DeleteKey HKEY_CURRENT_USER, strKeyPath 

	End Sub
 

	Sub CheckError

		If Err.Number <> 0 Then

			strOutput = strOutput & "<font color=red>Error</font><br>"

			strOutput = strOutput & "    Error number: " & _

				Err.Number & "<br>    Error description: '" & Err.Description & "<br>"

			Err.Clear

		Else

			strOutput = strOutput & "<font color=green>Successful</font><br>"

		End If
