So today i was using google and clicked on the “cached” link to see the google cache of my search result and to my surprise what i see is a Google Error which says ” We are sorry  but your query looks like similar to automated requests from a computer virus or spyware application….. blah blah… “ 

Google called me spyware/virus . And i am sure my computer didn’t have any spyware or virus because its my office computer which is protected very well ( i have not had any problem in my computer since more than 2 years ) . Google help says 

In a nutshell

• This message appears when Google detects automated querying coming from your IP address, thus causing a quick spike in traffic on http://www.google.com
• The error page most likely displays a captcha (a squiggly word with a box below it). To continue using Google, type the squiggly word into the box. The captcha image helps us determine whether traffic is coming from automated robot software or individual users.

I dont know whats wrong.
