For awareness & to question how @VirginMedia cannot stop these calls.
Call from [REMOVED]
It's tech support about the problem with my broadband.
Usual Patter
Run EVENTVWR (on a windows machine)
Point to the list of events & say there are bad things happening (they are not, these are normal)
Direct you to download remote control software by accessing a link to a link shortener with /virginsupport9 in the address. This downloads remote desktop software which they then use to take control of your computer & convince you to purchase some software that isn't needed.
At that point I asked them what they were doing with their lives and we parted ways.
Given that they are masquerading as a VM number, why can't they be blocked?
They clearly are able to target Virgin customers by virtue of the numbers used - at least here in Nottingham, you can.
[MOD EDIT: number edited in case it's an innocent number being spoofed]
