Zone alarm suite has this and it seems even when its disabled (the IM part of z.a) it still displays imsecure is typing a msg for a sec.
it may help if she disables IM protection by going

opening the main zone alarm window.
clicking IM Security on the side.
then sliding the protection down to off
then clicking the setting tabs and click the advanced button
untick all of those check boxes then click ok and exit

it should fix it hopefully
