Below is an article that I found this morning: "Web browsers are one of the main ways that malware finds its way onto your machine. Tests carried out by NSS Labs looked at the five major players, Chrome, Firefox, Safari, Opera and Internet Explorer to see which offers the best protection against more than 700 examples of real-world malware.
And the safest is... (Drum roll and a long, reality TV-style pause...) Internet Explorer 10, blocking 99.96 percent of known malicious downloads." (read the rest of the article)
For years Internet Explorer has been lambasted by the press for being insecure. Unfortunately I will have to let its "track record" speak for itself.
Over the last few years Microsoft put in a lot of energy to improve this application. What is interesting is that Firefox and Chrome were considered more secure then IE for a long time, but unfortunately over the last few years their security enhancements have been falling behind.
