Yahoo browswer keeps freezing after downloading rogers new antivirus software? - rogers yahoo norton

Rogers Yahoo browser "freezes" .. I get an error message that ... Microsoft encountered problems and must be ended, and so on. etc.
I will both play .. freezes when I try again
I am somewhat in the browser .. then crashes when I try to make another one
This has only happened because the protection of Roger's new Download Center .. (Norton)
Every time I restart happen if I use Yahoo continues.
If you use MSN, for example .. I do not understand the problem.
