Just got a phone call and it was not on the office phone line, it was on our backup line. The incoming phone number was blocked.
Indian sounding accent. I am from the Microsoft Systems Support, may I speak to the owner of the computer.
Well sir, we have a number of computers here, which one.
The one that belongs to Kathy.
Kathy was also in the office, so I handed her the phone.
Ma'am you have downloaded a malicious file and we need to help you clean it up.
Thank you sir, what do I need to do.
Boot your computer.
It is already running.
OK, do you see the start button?
No, do you mean finder?
Ma'am it looks like a flag and it is on the bottom left side of your screen.
The thing on my computer on the bottom left side of the screen looks like a happy face.
Ma'am you should have a flag shaped icon to start your Windows computer.
But sir, it is a Mac.
Sorry to have troubled you Ma'am; goodbye.
