PC froze after installing Internet security software

my pc froze right after i have installed trend micro internet security pro. i have rebooted it for so many times already but it would only work for a few seconds then it would freeze again. it only seems to be working well whenever it's on safe mode. and so i removed trendmicro on startup and rebooted on normal mode again.. but now it wouldn't even get to logged-in on my account. does it have something to do with the installation of trendmicro?

i wish to do some troubleshooting steps but would really need a guide to do it.. please help me in this problem.

thankyou.:)
 
Before Trend Micro did you have another internet security suit and if so a) what was it and b) did you uninstall it completely before installing trend Micro?
