About:blank is a special page within most browsers. It can appear due to problems, malware, or if there's been malware that's been removed.
About:blank is simply a benign page that’s built in to your browser. It’s not something to “get rid of”.
It’s the page that your browser displays when it has nothing else to display. That’s all.
The problem, of course, is that about:blank can show up unexpectedly, and people get confused about why, and what to do next.
About:blank isn’t really “about” anything.
The word “about:” is just a keyword that many browsers use as a way to enable some additional functionality or display standard pages. You can read more about about: in this Wikipedia article.
About:blank does nothing more than display a blank page.
That’s all. About:blank is nothing more and nothing less than just a blank page that’s built in to your browser.
Most browsers have to display something in the browser window and IE is no different. In various situations, when IE can’t figure out anything else to display, it might well display about:blank.
Sometimes it’s malware
Let’s be clear about something:
about:blank is not malware.
However, occasionally, malware will explicitly mess with IE and about:blank will be displayed, but only as a symptom. Malware will sometimes break something and IE will be unable to display a page. In cases like that it simply displays about:blank.
The solution in most of these cases, of course, is to run up-to-date scans for malware.
Sometimes it’s malware removal
Since malware can mess with your browser and often leave it in a confused or broken state, it can be left in that state when the malware is removed.
Similarly, removing the malware might also cause IE to become confused. Perhaps it was displaying a page provided by the malware – once the malware is removed IE has nothing to display, so it can only display about:blank.
Almost every time the solution is quite simple: change your home page back to what you want it to be.
Malware loves to play with your browser home page, and as a result, that often gets confused.
About:blank as your browser home page
Your browser home page is the page that you see first when you initially fire up your browser, or hit the “Home” button
Frequently, the default home page for IE is http://www.msn.com or some other Microsoft-related property.
Sometimes, malware or other misfortune can leave your browser configured with about:blank as the home page that displays whenever you start IE.
Let’s fix that.
Click the gear icon (or the Tools menu) and then Internet options.
On the very first tab (the General tab), the setting for home page is at the very top. As you can see above, it’s set to be about:blank.
It can be whatever web page you want it to be.
Let’s say you want it to be “http://ask-leo.com”. Simply type that in, overwriting the about:blank:
After entering whatever it is you want, click OK.
Now, click the Home button in IE.
Now, your browser will open whatever page it is that you’ve specified when you click the Home button and when you first open the browser.
