Somebody has hacked her Mac and is deleting applications - 0%
She moved stuff from the Dock by mistake and didn't realize Messenger installs with Office - 100%
I can put money that this is the case. For a new user, sometimes new users drags or rearranges icons off the dock by mistake.
Does she have a Firewall on and does she use unprotected (no password) wireless network?
Password or not on the wifi is not relevant to this because OS X in the default setting cannot be hacked this way. If there is no password (or easy password) on admin account then that's user error.
This is possible. My friend who is a hacker/geek, can hack Mac OS X if he wants to over the unprotected wireless network and it took him an hour to do it. He said Mac OS X is not as secure as you think it is.
It's always a "friend" who claims he can do this or that. There are 2 possibilities
- Your friend knows he is BSing, he knows he really can't take control of OS X remotely.
- Your friend doesn't know he is BSing. He thinks it's as easy as hacking windows, with no knowledge on OS X security. This is more likely the case.
