Definitely. I find it hard to find any reason why something like Babylon (one of the things I remember that IM might install) should not be called "crapware" or malware. Babylon hijacks your browser and then becomes practically unremovable (it can be removed but the people savvy enough to remove it are the ones savvy enough to never install it).
If users like this software so much then why do the creators of this software have to work so hard to make it next to impossible to remove? Who would want to get rid of software they love?
