Your site has been hijacked. There are probably thousands of hijackers out there. Your content is appearing on their site. They may hijack hundreds of other sites. Search engines then see their site as being huge, with tens of thousands of pages. Here is one public description of the hijack tactic and what you can do about it. http://www.xencraft.com/resources/web-theft.html You must block their server. You can also email Google (help@google.com) and report the hijack. They may take action, but there is no guarantee. Search the web for "hijacked website" to find more information on what you can do.
first time seen this kind of problem if some site hijacked then their would be displaying hijacked but its first time i see hijacked in cache
2 days ago, my site http://www.indian-banks.co.in/ was hijacked, Though it is back to normal, SERP is still hijacked for some of the keywords. eg- for kw: "vacancies in bank" earlier my site was ranked first in search engine, but now one spammy site was replaced there. Any help is appreciated, thanks
Check the source code of your files.. Someone might have injected a malicious code which is redirecting google from your site to them.
