Your browser's Home page had hijacked...

Beware of Homepage Hijackers!

You visit a certain web site or install a certain free program on your PC only to find later that your browser’s default home page, and /or search page has been changed. And at times, certain Browser Helper Object (BHO) gets added in your browser. Next time when you restart your browser, amazingly, you will see that your browser has been hijacked and pointed straight to their web site instead of your default home page. Home page hijacking is not a new trend. In fact, when you install a browser, its default home page always points to the home page of that browser. You have to change that initial setting for your own home page; for example; to your favorite site But, initial default settings from Browser Company can readily be changed and it is not termed as real hijacking. The hijacked site always loads with lots of advertisements, pop-ups, make-money-messages or porn sites that do business through those sites. Some hijackers install pay-per-call long distance international dialers without your knowledge.

Help! Hijackers are here!

You may encounter two types of browser homepage hijackers. The easy one and the hard one. The easy one type hijackers simply change your default home page to their page which can be changed back to default or previous settings through Browser’s Options/Preferences settings. Now you only have to remember to never visit those sites again or never use those particular applications that had hijacked your browser. On the other hand, the hard one hits you really hard and does not let you restore your default browser settings easily. If you restore the browser setting, then, upon Windows restart, it will again change the settings. Some hijackers won’t allow you to change back to default home page by changing registry setting that gray out the restore options. And a couple of hijackers lock Windows registry that makes impossible to remove them.

How hijackers are installed

Hijackers can install through various ways. If you click a certain link to web page that contain malicious hijack code in the form of ActiveX controls or java script that runs in browser, it will install in your computer. The ActiveX can do practically anything on your computer and hijacking your home page is a simple task. Some hijackers install as standalone exe files and disguise as enhancements, updates to certain popular application etc., which you accidentally run on your browser. Similarly, if you install some application that depends on advertisement across Internet; for example, Tetris3000, they change home page of your browser with your permission. If you bring back your browser settings to the original, the application looks for the browser settings and may not start if it does not find its web site as default home page. Hijacking Homepage is a sort of Internet Traffic Stealing tricks that are used for generating web business. Some time, Hijackers installs with your express permission and most of the time without your knowledge. Some hijackers also made entries in the Favorite / Bookmark folder of your browser.
