Reason #1: #
A hacking group is actively exploiting a zero-day exploit in Internet Explorer to infect Windows PCs with malware, according to researchers. A team from Qihoo 360’s Core security unit “say an advanced persistent threat (APT) group is using the IE vulnerability on a “global scale,” according to ZDNet. The vulnerability is being exploited using an infected Office document, loaded with something called a “double-kill” vulnerability.
Reason #2: #
Not only is IE 8 already an outdated browser without the latest features and performance improvements, it has been completely unsupported with security patches since Microsoft ended support for Windows XP on April 8, 2014. If you have to use Windows XP, that’s one thing — but you shouldn’t use Internet Explorer anymore.
Reason #3: #
Possibly the most important reason, Apis Support and WP Engine Support are Mac based teams. Mac no longer supports IE and does not even allow it to be downloaded or installed. Your support team needs to be able to recreate your issues to troubleshoot and resolve any problems you may run into. We cannot troubleshoot IE.
