Fix: Toolbars Missing After Installing IE 9
If you find any of your IE toolbars disappeared after upgrading to the Internet Explorer 9 from IE8 or IE7, you can always re-enable them again. This happened to me too after I installed IE 9 into my computer, and then I found that my Alexa toolbar and Google toolbar gone missing when IE 9 opened up for the first time.
It can happen because your newly installed version of browser has probably reverted all settings to default and you may need to set everything again. Well, it may of course not always be the case. Sometimes your toolbar just gone missing suspiciously and if that is the case, read the last 2 paragraphs for more info about what might be happening to your computer.
To enable toolbars in IE 9, simply right click anywhere in the empty area beside tabs or address bar, then select the toolbars that you want them to appear in your IE9.
If your toolbar doesn’t appear to be in the list (via above method), you probably have it uninstalled either unintentionally or someone just did it. In this case, just re-install the toolbar again. If it goes missing again even after installing a new one, then it might be a virus infection.
Spyware, Adware or a Virus Infection
The second possible reason of toolbars gone mising being that your computer may have been infected by an adware or virus that is able to bypass your security and inject or alter the setting of your browser (which is very bad). These adwares and viruses often come from the malicious toolbars or software you’ve installed. It can be dangerous if you often access websites such as your online banking page. In this case, you should install an antivirus software (we recommend avast free antivirus) and use it to scan and eliminate these threats automatically. If your antivirus found that one of your toolbars is suspicious, you are advised not to install that particular toolbar ever again.
