Microtech scam/ransomware was on a computer at a remote location. Said they needed to call a 1800 number to get virus removed. This user did that and paid $300 dollars to have fake company remove virus. Got a text from him and said they are in there right now controlling computer and "trying" to remove virus. Should he power off right away or should he let them do their thing so he can use his pc again since he paid the money? I told him to immediatley power off computer and wait for them to call again.
