Internet Explorer has also had a number of security problems, even to the extent that the French and German governments recommended users stop using it. – BBC news item January 2010.

The usage estimates for web browsers are based on the percentage of visitors that use a particular web browser. The estimates are based on the visitors to a single ( or preferably a group) of websites. For this reason inevitably there will be differences in the figures produced by the various sites. A number of other factors can influence the figures, to produce either an overestimate, or underestimate of the actual browser usage.

The figures below include a breakdown of Microsoft’s internet Explorer by version. The majority of people using that browser are still working with an out of date version. This is likely to be true for other browsers as well.

You must ensure that you promptly implement the security updates regularly posted by the browser vendors.
