My Firefox always automatically  started during pc start up and rediret the homepage to the bizrumour.com and sometimes newspedia.com wth!!! . I never set the homepage for that useless website. I think my computer is infected by a malware  or virus. I searched on the net and didn’t found the ultimate solution for it. The only option is to remove the malware using Spyware Doctor  or Malwarebytes. But I prefer the free version of Spyware Doctor it is bundled with other google aps. Once you install it just make a full scan and do not open your browser at that time.

Screen shot of  Spyware Doctor. Look at that, there are lot of malware and virus including Trojan.buzus.

Trojan.Buzus opens a backdoor on the infected machine and tries to steal various information like personal financial data (like credit card numbers, online banking details etc.), passwords from various email and FTP applications (like Trillian, Microsoft Outlook, CuteFTP etc.) It also tries to compromise security settings of various security related products.

Update !! I just found out that the invalid windows process called nissan.exe is a malware also.  Open your task manage and kill that process and run the scan again. I think my computer is free from malware for the moment but my firefox browser still behave like a shit. I cant use my right click so I need to install safari and google chrome as alternative. I will update the solution on how to completely remove the “browser hijacked” malware once I found the solution.
