some spyware/worms/viruses use search terms on google to find new vulnerable computers to attack, by using the power of google's search engine to locate servers running versions of known insecure software such as web servers, bulletin board systems etc that can be exploited to gain full access to the computers (ie. hack them).

examples of using google to return information leaked by poor configuration of the servers on the internet and more information about what it is, can be seen here:

google is trying to limit their ability to do this, by putting this blocking page in the way and checking it's an actual human user making the search - what algorithm or matching system they use i don't know, but this is why they do it.

I think your ISP u using to connect to internet had been banned by googleWebsite. Cause there is no other reason that u getting this answer from google, or maybe your ISP's cache is old.

use some good updated anti virus with anticipate
to scan your system.
try to avoid watching some specific sites from where you can get virus attacks

Maybe google is blocked or your internet does not allow google itself.
