Q: Help! I was scammed, now what?

You don't have a virus or a trojan horse; you didn't to begin with - nobody in the world would know what you have on your computer. Scammers use this to part you with your money.

You should not only completely erase your hard drive and reinstall the OS, but you also need to call your bank(s), credit card companies, etc. as nobody could know what kind of information he was able to steal off your computer. You also need to change ALL your passwords everywhere.

So, call your financial institutions first. And change your passwords everywhere.

Next, backup your personal files, videos, pics, etc.

Then use recovery (Command + R or Command + Option + R) right after the startup chime to connect to Apple's servers. When you see the Utilities window, choose Disk Utility to erase your hard drive. When finished, choose to reinstall OS X. That is the only method to make sure nothing of whatever they did still remains.

It's nothing but a scam.

If you run into a problem like that again, you can force quit your browser by pressing Command + Option + Esc on your keyboard.

the terminal thing is a smoke and mirrors show, they show you a bunch of network processes that the computer uses every minute of every day and stop and say "look, theres the virus" and you could be looking at a printer packet from six weeks ago.

I can't say they didn't install something no one knows about but for the most part these are crooks, not computer genius either, just garden variety con artists looking to get on your computer, do their script and get money wired to them. after that they are gone so wiping your computer would erase any doubt you might have but it's a bit extreme and I don't know if you need to get that extreme

team viewer for instance is not malware, its used by IT people to do their job, legitimate work, but crooks use it too because it's very simple to set up and it doesn't arise a lot of suspicion. Here are the instructions to delete it. It's a pice of software, nothing more.

I don't know support.me. was it "logMeIn"?

that's another legit software used by crooks and it is easily removable.

what you need to do now

call you bank

reset your passwords

make a new admin account and make your current admin account into a standard account afterwords. delete any startup items in your old admin account that are "log me In", "team viewer" or anything else that looks suspicious.

backup your computer with Time Machine either way.

if they didn't have you log in as root, and install a key logger they are not "experts" just “******", and trust me you would had to go through some memorable steps to have that happen.

Enabling and using the "root" user in OS X - Apple Support

and that HAS to be done by someone sitting at the computer, not over a VNC remote session.

likely there is one or two things you need to be concerned about but if cash was not wired that's the biggest one.

There is nowhere to check if they installed something. And no, you're not being paranoid because you don't know if they did anything or not. They are crooks - so they are not to be trusted. It doesn't matter if they're computer geniuses or not - they're crooks, so I wouldn't trust anything they say or do. Hence my suggestion to erase the hard drive. That is the only way to know that you are starting with a clean slate and it is what I would do (aside from calling my banks, change passwords, etc). But of course, the decision is yours.
