An unauthorised search bar from www.ezcybersearch.com keeps appearing
on my Internet Explorer browser and I won't to stop it and all other
unauthorised modifications.I have I.E. version 6.0.2600.00 but it also
appeared on my old browser version 5.5. I'm not sure if this is
relevent but I've tried deleting all temporary and temporary internet
files inside my windows program and all cookies but my computer won't
let me delete some programs like "index.dat" (insidea folder called
"content.IE5" inside my temporary internet folder)because its always
in use.
