Computer is infected by a virus or a malware, what do I do now?
If I type http://bharatvinzuda.com in browser I go to the correct site but from elsewhere, for example if I click the link at https://www.google.com/search?q=bharatvinzuda.com&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a it goes to http://aozpta.mrbonus.com/.
Why can this happen? How can I fix it?
The tags are probably wrong on this question, but I don't know what are the right ones.
EDIT: The result is same if I search at bing or yahoo but duckduckgo takes me to the correct site.
