Vista - Strange File

Can someone help, my daughter finally talked me into getting a wireless router and now when i run ccleaner i have noticed it won't clear an IE file named :

C:\Users\Appdata\Local\Microsoft\Windows\Temporary\Internet\Files\Content.IE5\DQ1WJL1M\109[1]

i am totally confused, checked it out by opening hidden files and folders and it has this :

res://C:ProgramFiles\VirginBroadbandWirless\WirelessManager\LOC.dll/oem/109

cannot delete as it won't allow me just keeps saying try again, am i supposed to leave it alone or, if i am supposed to delete how do i , any help would be appreciated thanks !

Thanks in advance !
