You might have seen some warning ‘this site may harm you‘  such as this one on the search result page, when you performing search in search engines. When you click the link with harmful message, another warning will be displayed, details the possible treat to your computer. Visitors absolutely stay away from this kind of websites, resulting decrease in visitors and earning.

As a webmaster, this is nightmare. Even worst if the webmaster not even aware that their website is infected by harmful malware.

When Google Webmaster came with it’s own lab feature, one of the first lab feature introduced is Malware Details. Malware Details will tell you which pages are infected with malware in detail including type of treat and the URL, or if it is clean from any treat, you’ll get the result as mine above.

The easiest way to know if your websites are effected or not, is by performing search using your website name as the key phrase by your own, but I doubt many of you do that often, including me.

I found this tool very handy because I logged more often to the Google Webmaster Central monitoring my websites rather than perform search on the search engines.  You’ll get to know any issue happen to your websites, before being informed by someone else, or when you already start losing money.
