Browser Hijack


I got questions regarding term 'Browser Hijack'. It is most common attacks which modifies your default start and search pages. It is just small chunk of malicious code which alters your computer's browser settings so you are redirected to websites that you had no intention to visit. It changes/alters default home page, blocked some interesting websites(like orkut) , add bookmarks, redirects users to pornographic sites, generates unwanted pop-up windows. Sometimes, It disables Internet Options under Tools menu so you don't able to reset it.

I answered on same subject on Yahoo! Answers. It selected as best answer!! That guy had troubled surfing ORKUT His browser hijacked. So, he didn't able to open specific website. Please check following real screen shot.


Purpose - Browser Hijack:
(1) Advertisement
(2) Intentionally blocked some websites
(3) Increase traffic on specific sites
(4) Malicious activities

Medium - Browser Hijack:
(1) Email
(2) Messenger
(3) Requested link

If you are skilled then you can find affected areas in your system manually or you just need to install a software named 'HijackThis' which is designed by Trend Micro Incorporated. It is absolutely free software and you can download it from following site.


Then install it and scan your system with help of this. This program scans the locations in your computer system that may be modified by browser hijackers and fixes any problems found. You can download the HijackThis software from following link too.
