How to find out if my computer was infected with malware via teamviewer?

Hi,
today I got a fraud telephone call (I found out later) and I was so **bleep** to start teamviewer on my mac and gave the caller connection ID an pwd (they wanted to show me the problem with my computer). But I don't think that a connection was established and under preferences of teamviewer I have configured the settings to confirm all incoming requests. Neverthless I wondered if I can find out somehow if files have been transferred to my computer or not.

Thanks for your help.
