Browsers can leave you and your system open to danger. Most browsers allow you to run small downloadable applications, such as Java applets or ActiveX controls.
Your browser may allow you to visit sites which will automatically download malware, such as viruses or spyware. It may also allow you to visits sites with objectionable, or even illegal content, such as pirated software or video files, which may themselves be infected with malware.
Fortunately, browsers generally provide a range of security settings, which can alleviate or eliminate most major security problems. Over the next few pages we’ll look at how you can configure the security settings in Internet Explorer and Firefox.
