Windows 7: Windows Defender + Trend Micro Titanium keep switching off/won't open

I was wondering if someone could help me, I have Windows Defender and Trend Micro Titanium 2013 installed on my Windows 7 laptop and the past few days, they keep switching off and I can't open the Trend Micro Titanium 2013 console at all, even after re-installing it and rebooting my laptop. Does anyone have any ideas as to they both these programs aren't working properly? Do I maybe have a virus that is causing this behaviour?

Windows Defender in Windows 7 should be turned OFF anytime another anti virus program is installed.
I'm surprised that Trend Micro didn't turn off Windows Defender when it was installed.
Never have two anti virus programs running at the same time.
Check Windows Defender and make sure it is OFF.

Windows Defender - Turn On or Off

Make sure you reboot.

Thanks for your reply. I've turned Windows Defender off and rebooted but Trend Micro still won't open.

Try the "hot fix" and report back Stuck at "Starting your protection" when accessing Titanium 2013 console

Tried that and it didn't work what's odd is that the icon is in the system tray and says "Protected" yet I can't seem to find the process in the Task Manager.

I think I've managed to fix it! I saw this and followed the Missing Path Variable steps Cannot open the main console | Trend Micro Titanium and I can open the console now, I will report back it it stops working again. Thank you all for your replies anyway!

Very good!
