Even though I have set google to be my home page using tools/options/general, it resets to funmodes search.
How can I stop it?
Make sure no Add-ons are resetting your settings.
Sometimes Toolbars can take over the homepage.

Thanks. I also ran Microsoft's Safety Scanner, at www.microsoft.com/security/scanner/ - I ran it in deep scan and it found 5 items of malware including a Trojan Horse that captured the tool bar, and it got rid of them.
