Web browsers are presented by many variants now. Each of them has its advantages and disadvantages as well.
In today’s computers there must be one or more web browsers installed; some of the most used and known browsers such as Internet Explorer, Mozilla Firefox, or Opera, to name a few, should be present in the system. Most web browsers have significant security defects.
The fact that web browsers are the most regularly used by almost every Internet surfer made them the most vulnerable in what concerns security, and in order to protect our information and our most important personal data, we have to configure them in the correct way which will offer us the desired level of security. Many users of the various services of the Internet do not know what severe results can come from not securing their web browsers. Web browser can be provided with a certain operating system which is not configured to supply a high level of security and this can lead, in a relatively short period of time, to a wide range of system problems that can be caused by anything from a spy ware that can be automatically installed without your knowledge or hackers or impostors that can take full control of your computer and use it for their own dirty work.
Any provider or manufacturer of the computer hardware and software should pre-configure the browser in a secure way before to sell the product, but there are many cases in which the user needs to configure the browser further or to install new security updates or patches, for example, the new security vulnerabilities may have been revealed after the software was set up and packaged by the manufacturer, or a user may need to visit a specific web site that requires the installation of a new software to enable the view of its contents which may open more possibilities for vulnerabilities to be exposed, or a user may open a web page that have some malware embedded in it.
