# Phishing/Malware Detection

You can enable the Phishing/Malware detection in the "Security" preferences (only for registered users). This feature ueses the Phishing/Malware detection feature that is provided by Google. If iCab should open a web page where google suspects that this page is used for phishing or which contains malware, iCab will display a warning. iCab will not report the URLs you're visiting to google. Instead iCab will download or update a list of phishing/malware sites approx. every 30 minutes (only if this feature is enabled). So all the checks can be done locally on your computer, without any privacy issues. The first time this feature is enabled, it can take a while until the phishing and malware lists are completely downloaded. Later only the changes must be downloaded, which will be much faster. In the preferences dialog, you can see when the last update of the lists took place.
