Can a virus do this or do I have a teenager who's possibly up to no good?

Common virus . The teenager is blameless.

Is it a common virus? I was hoping. My son said the computer was doing weird things and the security software detected a threat before the time stamp on the document.

It makes sense to me that if viruses can actually change firewall settings and things like that, then maybe it could print something unwanted.
