Starting early afternoon (today, 31 January 2009) any search result on Google shows a warning message 'This site may harm your computer' - for all sites, including Science Centric.
Are all servers on the Internet infected? Probably not... It seems that it is just a Google crash. We hope they will fix the issue soon.
The feature, when working correctly, enables users to be warned of sites which may potentially carry malware and affect the users computers.
Update: The problem with the search results has just been fixed. However if you want to access 'Webmaster Tools' in your Google account it still issues a warning message 'We're sorry... but your query looks similar to automated requests from a computer virus or spyware application.'
Update 2: The access to the 'Webmaster Tools' is OK now.
Update 3: An explanation has been posted by Google.
