Fake URLs created automaticly

While checking my indexed pages in Google and Bing. i have found below links in search engine index listing. i am getting 404 errors in google webmaster tools. i got wordpress installed only. I dont have any plugin or any other CMS (Joomla) which may create those links.
how should i remove extra strings/values? what will be the code for .htaccess

Please ignore 2 spaces between url and strings/values.
