My default browser is not IE, but the links in the Secunia PSI keep opening in IE. Why is that?
Some links are set by the Secunia PSI to open in IE. This is because Windows Update is unable to function properly when opened by a browser other than IE, since this website employs ActiveX technology only implemented in IE. For information on how the PSI determines which browser to use, see the FAQ entry below this (Here).
