SearchScan by Yahoo Search alerts you to websites with potential security concerns such as viruses and other dangerous software which may harm your computer.
What SearchScan helps protect against
Just visiting some websites can expose your computer to dangerous software like viruses and spyware. If we detect a dangerous website in your search results, we'll let you know by displaying a "Dangerous Downloads" message for that specific search result.
