Anti virus sent a file for analysis automatically

[red pill 0]

Few days ago my Anti virus sent a file for analysis automatically without anything suspicious happening in my PC. How can I get more information about that incident?, I don't even know what that file was.

If you have submission logging enabled (which you probably have, otherwise you probably wouldn't know the file was subitted), you should see the path to the file listed in the event log. Typically if a suspicious file turns out to be malicious, a detection will be added soon.
