Not sure if this a "virus" on my machine
You may rule that out. There are NO viruses that affect a Mac running OS X - none.
or someone hacking into my system via Bluetooth.
Nothing is impossible, but that is quite unlikely. The range of Bluetooth devices is about 30' (10 meters). Additionally, someone would somehow have to pair a device with your computer.
The stuff you posted has a .exe suffix. That is a Windows suffix and will not execute on a Mac. Did you download something perhaps (from a web site called "collegefan.org21" or someplace else)? Malware, while rare, can intrude from unknown sites.
I would probably reinstall OS X completely (after making a good backup).
I do not know how a malfunctioning mouse would create text like you describe.
Ran my organization's enterprise anti-virus software last week and nothing was quarantined, but I wasn't expecting anything to be found.
And no, never visted any site called "collegefan" or the other 2 URLs that were listed in this garbage text that I've watched self-execute the other two times this has occurred. Wish I'd gotten screen grabs of those previous two incidents.
I've been using a Mac since the mid-90s and have never seen anything like this. Again, don't know if the wireless mouse-Bluetooth combo has anything to do with this issue, but this stuff only started happening after I started using these tools, so it seemed obvious to start trouble-shooting there.
I'm still digging for clues, esp since I don't know what was downloaded before I took over this machine.
Thanks for your suggestions.
Just looking into this possible Bluetooth exploit. I have a couple of MacBooks that I picked up refurbished. Strange things had begun happening with the computers like messages in iChat that did not belong to me and optional software installed that I did not choose.
Last night my computer was connected to a network when I had the ethernet unplugged and wireless turned off. This would not be a big deal as maybe just a glitch with the wireless control but I also had my router power cable disconnected.
Turns out that I was connecting over a BlueTooth connection between my computer and my iPhone 5. Not sure how they managed to get into the iPhone 5's settings as it is not and never has been Jailbroken. I checked in the MacBooks and sure enough my bluetooth was configured to connect to a modem. Also, There are Java developer applets in my system with what appear to be full permissions.
Not real worried about it as I brought it upon myself by buying used MacBooks. As I am a computer networking student I find it rather interesting.
