teamviewer fraud - how to protect mac
We were taken by a nice Indian gentleman who convinced us to install teamviewer and let him help us "fix" a problem with our email (he said it was causing problems with the internet). How do we make sure he didn't install anything malicious (i.e. like a keystroke trojan, or get our banking info, etc.)?
We are afraid to reconnect that pc (macbook pro with mountain lion) until we know it won't send our into around the world.
We did a search on any files on the hard drive that were modified during the call/teamviewer session.
We did see that there was activity in the metadata files associated with our contact list on that machine - i.e. during the call there were files created/touched under Library-Application Support-Address Book - Metadata. There appeared to be a file for each contact ... ABPerson.abcdp
Also files modified during that session included some files in Library-Caches-Metadata - Safari - History
The Indian gentleman told us that he could fix the error - he pointed it out in the teamviewer window - if we sent him money.
I unplugged our cable modem and he quickly hung up on us.
-What can we do to make sure we are safe to use this mac on the internet again? (please don't tell us you can fix it and ask us for money - we aren't falling for that one again)
MacBook Pro, iOS 6.1.2, mountain lion- not sure of version
