- One sign of a hijacked browser is the appearance of unknown bookmarks and the alteration of your browser's homepage, the webpage that opens as soon as you open your browser, without your permission.
Webpages Won't Load
- If webpages, especially those associated with security software, will not load, this is another sign of a hijacked browser.
Large Number of Ad Windows Open
- If there is a constant stream of advertisements opening, particularly when you browse to reputable webpages, this may be a sign of a hijacked browser. Another possible sign are ads that seem unlikely to be sanctioned by the website you are browsing. For example, you should not be receiving advertisements for pornography while browsing CNN.com.
- There are many things which can cause sluggish performance on a computer, but the presence of malicious software is one cause.
Fixing the Problem
- Practice safe browsing by not opening untrusted websites or programs and keep your computer up to date with the latest security patches from Microsoft. As the old saying goes, an ounce of prevention is worth a pound of cure.
Remove Malicious Software
- If you suspect your browser has already been hijacked, Microsoft provides a Malicious Software Removal Tool which you can run.
