Laptop

[Caran]

Just put my laptop on and noticed 2 strange icons on the desk top. One say rrset up with a picture of pc screen, modum and cd. The other one says CT30031756_So ftonic-EngUK. This has a blurry picture of a screen and other things I cannot make out. I have also acquired a tool bar I didn't select which has a magnifying glass at the end, also my home page has change to this magnifying glass instead of igoogle. Can anyone help me identify what has gone on and what are these thing. Thanks for any help.
