Don't be afraid to admit mistakes, your boss willbe more likely to forgive you when you are actively taking responsibility. Trust me, he will like you for it, unless he is an ass but you can always make another FML :)

...does the company not have real-time antivirus?

This will be funny perhaps a year from now

Antivirus can never afford complete protection because of the nature of vulnerabilities, and even the best firewalls (which go up exponentially in price with respect to quality) can not block everything malicious for the same reason. Unfortunately many companies lack the funds, the foresight, or the knowledge to go with the best or even mediocre protection. I am sorry, OP. It sounds like you did nothing wrong. I hope your higher-ups realize that it was their mistake and not yours.
