Error: "Access to path 'xxx' is denied" when trying to end process from VB.Net

[Modulus]

I have an Anti-Virus in VB.Net, which has a real-time protection engine. Here's how it works.


1. Any process that is opened, it gets scanned.

2. That process that gets scanned, gets its MD5 hash taken from it, then compared to a string of MD5 hashes.

3. If the hash from the process is the same, a MessageBox comes up saying

Virus Detected!

and the program is SUPPOED TO automatically end the process when the MessageBox comes up, but, when I try to end it with code, it gives me an "'Access denied to path 'xxx'" error message.

This is my code for the function to end the program.

Private Function GetMD5String(ByVal strFilename As String) As String

        Dim cMD5 = System.Security.Cryptography.MD5.Create
        Dim bytHash As Byte()
        Dim sb As New System.Text.StringBuilder
        Dim scanbox As New TextBox
        scanbox.Text = My.Computer.FileSystem.ReadAllText("viruslist.txt").ToString

        Using cStream As New IO.FileStream(strFilename, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)

            bytHash = cMD5.ComputeHash(cStream)
        End Using

        For Each c In bytHash
            sb.Append(c.ToString("X2"))
        Next
        If scanbox.Text.Contains(sb.ToString) Then
            Detect.Show()
            Detect.BringToFront()
            Me.SendToBack()
            Kill(strFilename)


        End If

        Return sb.ToString



    End Function

If I insert

Process.Kill(strFilename)

I get the error:

Too many arguments to 'Public Overloads Sub Kill()

I've run this program as administrator, but it still hasn't done anything.

Any help would be greatly appreciated! Thanks.
