I havent checked my touchpad with CM9A2, but my Acer Iconia with CM9-ported had this appear too.
I did not have this 3/8 afternoon, and had my tablet off yesterday night 3/8, and turned it on today 3/9, and it appeared shortly after.
Very strange and suspicious to have an itunes logo-ed shortcut "self-install"
Hope some more people can shed some insight into this.
Are we android user's getting hacked/compromised? (beyond what Google is already sucking off our tablets)
