IE7 phishing filter

I tend to leave it turned off as any site I need to enter personal data into as in Banking etc I know exactly what their pages look like and the URLs, plus as many phishing issues come from links in emails asking you to update your user and password details etc to banking, paypal et al I delete all banking emails as they do not send emails asking for you to do those things.

also as I'm fully aware of phishing issues as listed above I also turn if off as it does slow your surfing a tad!

But if your not aware of what phishing is and looks like then its wise to leave on.
