I am going to make sure stupid things are turned off through msconfig
The only program I allow in the Start Up list is the anti-virus program ... and I probably don't even need to do that.
I do not use IE, I use Waterfox (64 bit version of Firefox) as a browser.
Have you checked her PC with Malwarebytes?
Have you tried What's Running?

It’s a new computer my niece has just gotten. If it were going for a month I would conclude virus, but this is right out of the package.

I will check the offending computer out in two or so days. Usually the biggest offender of everything is a virus program in the operation of scanning a hard drive.

IMO, unless you go for Russian sites or porn you are not going to often get a virus. Also don’t click ads.

I have run clean through a wireless modem without a virus program for years without a hitch.

I do have a copy of malewarebytes for when we need it. Great, I agree.
I can look at task manager and figure out the things that should not be running more or less, but every generation has a new bug.
