How secure is a Windows XP computer running iCamSource and nothing else?

[icamcb]

I have an old Windows XP running icam source and nothing else. Security is Windows Firewall, the free Avast and a guest style XP user account with no permissions. Because of icam it's connected to the internet 24/7. Is that a problem now that XP is no longer supported or is it okay? Thanks.

I wouldn't worry about it if you're just running Icamsource and Avast. No Dropbox running on it?

Thanks for your reply. No Dropbox, no recording of any kind. I'm just using icam as a live video feed.
