The Department of Homeland Security is echoing Trend Micro's advice to uninstall QuickTime if you have it on your Windows computer. While the multimedia program's working just fine, the security firm has discovered two new critical vulnerabilities lurking within it that could allow remote attackers to take over your system. Unfortunately, they might never be patched up: Trend Micro says Apple will no longer release security updates for the Windows version of the software, hence the call to jettison it completely.
