It is not only at times the anti-virus that doesn't succeed in chasing the difficult virus on the system Windows. Those will remain always.

If something has been installed on the laptop of Danielle it is probable that the system has not supported that drivers. And so the connection Web doesn't work. And it always appears: Error (X)!
I think that the installation must be removed. And to see if it returns to work well the System Windows.
There is otherwise the risk to renew the system Windows in complete way. And to make to also work well the connection Web.
At times when different drivers or programs it is installed, the system goes crazy.
It depends from that characteristics it is the Laptop (or PC), and from his installed hardware.
