Note for Windows XP Users:
On April 8th, 2014, Microsoft formally announced the Windows XP end of support. Because Microsoft no longer fixes issues on Windows XP, it has become increasingly difficult for Trend Micro to keep users safe on this operating system. While our internet security products can be installed on Windows XP, we encourage all of our users to upgrade their PCs to a more modern operating system which will provide greater stability and security.
