I am getting a virus intrusion message on my computer from Microsoft with phone number to call 1-888-544-8105. Is this valid?
Never be cheated by 1-888-544-8105 Tech Scam
If you see a pop-up ask you to call 1-888-544-8105, it means your PC may have been infected by an adware. It's a fake scan which can bring you lots of troubles. And you usually get infected by such threats via free downloads.
