Please visit the Yahoo!7 Search preferences page. SearchScan has three settings:

• Never display potentially harmful web sites in search results – Sites with hacking risks, dangerous downloads and unsolicited email will be removed from your search results.
• Alert me to potentially harmful web sites – Default setting. Sites with hacking risks will be filtered from your search results. Search results for sites with dangerous downloads or unsolicited email will be flagged with an alert.
• Do nothing to protect me from harmful web sites – SearchScan will be turned off for your searches.
