She knew she had fiddled.

Almost a given, man pages don't make sense to people of such expertise.

In safe mode (command prompt - no explorer extensions) perhaps?, or
could something have been protecting itself?

what about "tasklist /m" and check the modules loaded too.

disabled 3rd party browser extensions?

makes me suspect it is launched by an application which fails a dns
lookup first, and in failing does not open the browser.

sfc /scannow should maybe be added to the tasklist.

Yes, typically the systems are recovered by using your anti spyware
and anti virus tools in safe mode command prompt, where no explorer
modules are loaded. Better yet would be a PE bootdisk. I would
recommend running a chkdsk on each drive afterwards too; it is likely
to find errors.
