Windows 7 - How secure is Opera?

Opera has long been an underrated, feature-rich browser worthy of greater attention and a larger market share. It runs on Microsoft Windows, Mac, Linux, FreeBSD, Solaris, mobile phones, Nintendo gaming systems, and other now historical operating systems. Like all of the leading browsers, it supports Java and JavaScript, and its impressive, growing feature set pushes beyond today's standards such as tabbed browsing to include the likes of voice-controlled browsing, e-mail, and instant messaging. Opera has many unique security features too, and the granularity of its security controls easily beats that of most rivals, the exception being Microsoft's Internet Explorer.



When executed under Windows Vista, Opera runs as a single process (Opera.exe) of medium integrity, with file system and registry virtualization enabled (a User Account Control feature that allows users to operate without administrative rights), but without DEP (Data Execution Prevention) and ASLR (Address Space Layout Randomization).
