Virus infection causing browser to shutdown

I have an infection that causes my browser to shutdown whenever i try to search for keywords like kaspersky and mcafee.

It also cause me to be unable to chat with certain users in MSN messenger LIVE. those users are using Win Vista.

I tried to scan for those virus. and found some trojans. Already deleted them in safe mode. and the problem still persist. will try to post up the infected files later.

guys any idea what happen ?
