Acer Aspire 5738DZG - When resetting Windows 10 TriDef was uninstalled

I installed Windows 10 and all my programs were ok. After a couple of months parts of Windows 10 stopped working. I reset Windows 10 but in doing so found most of my programs had been uninstalled.

I've been able to reinstall most of my programs but unfortunately cannot reinstall TriDef which was installed on my computer when purchased.

Is it possible to reinstall TriDef on my Acer computer?
