Today i was searching using Google.com but every result with links showed 
warning visiting this web site may harm your computer! That time i didn’t realized that it was a false warning. I was wondering why Google malware detector showing every spam result. I went to tgdaily to read latest news and found that Google News was affected yesterday with this problem. Today Google search engine was affected with that problem. Every website it returned in the search has the warning “This site may harm your computer”. After clicking on the link it showed safe browsing diagnostic page and the Google warning page blocked users from going to those sites. Now it fixed. To see the screenshot and and to read more info go to this link : Google Error
