Infected by popup?

I don't see any problems with your router.

I was just pointing out a possible source of spyware/infection if you have symptoms, and the PC itself is clean.
You can inquire of whomever does manage the router whether the Router password has been changed.
If it has, they should tell you what it is so you can write it down.
