I have a weird problem when I Right Mouse Click any of the drives in My Computer (Including removable drives). Immediately MSIEXEC.EXE runs and attempts to install Roxio 6 (already installed and working OK on my PC). When I cancel this twice, the original click is actioned and allows me to view the entries on the right mouse click window. If I then select one of the options (e.g. Properties), the installer runs again - after cancelling again the properties box is displayed. In task manager both KNLWRAP.EXE and IKERNEL.EXE are left running. No viruses are detected and no spyware has been detected by Spybot.
