It seems I can't convince them the problem is at their end....or
perhaps something else is going on here ?
The burden of proof is on the accuser. Send an e-mail message to
Videotron.ca via your primary Videotron.ca e-mail account, outline the
problem and Videotron.ca's response, and demand that Videotron.ca
provide evidence, in writing, of your computer doing suspicious or known
bad things. If Videotron.ca does, post it here, and you and the list
can work to confirm/ isolate the problem(s) and fix your computer. If
not, Videotron.ca is wasting your time.
