This page aims to help you remove Error Code 0x80073b01. These Error Code 0x80073b01 removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Important. Read this. Error Code 0x80073b01 is caused by a Browser Hijacker application. Browser Hijackers are considered a form of computer viruses, yet with somewhat limited abilities to cause real trouble. They can be easily characterized by the many ads that will torment the affected users, as well as the possible browser redirects, which are, in many cases, just as irritating as the pop-up ads, if not more.

We feel that it is important to provide you with as detailed information as possible, so you are able to combat this malware effectively.

How did you get infected by Error Code 0x80073b01?

There are a number of ways in which this unfortunate event might have transpired. We will list the most common and widespread ones. For good measure we will also include some useful tips on how to prevent this from happening again in the future.

  • Look out for compromised executable files attached to e-mails. This is a very old practice, but it is still used regularly. Sometimes it might be especially hard to notice that you are indeed looking at a fraudulent e-mail, so our tip here is to always scan any files before opening them. Better safe than sorry.
  • Actually clicking on the ads and downloading anything as suggested by Error Code 0x80073b01 might turn out to be your downfall. You should completely ignore anything suggested in the advertisements. It is also important to remember that viruses are designed to be treacherous, so do not be surprised if you are greeted with intruding messages informing you that you have missing codecs, plugins, software updates, or even that a virus has been detected on your system. Even if some of the above is indeed true, it would be a coincidence and you can definitely do a lot better than download software from unsafe and often fraudulent sources.
  • If you are using p2p download methods and file-sharing websites it is important to remember that they often contain unpleasant surprises. Very few torrent and file hosting websites provide strict control over what gets uploaded there and by whom. So it is certainly a good idea to always scan before opening anything downloaded from such sources.
