Wow, I've disappeared for a few days!
Anyways, I've gotten something similar, yet dumber.
"There is a new worm/trojan going around! No antivirus program knows it yet! Download this file to trick the virus into thinking your computer already has it so you don't get it!
P.S. Your AntiVirus will go crazy when you download it, just ignore it."
Not those EXACT words but I swear that's basically what they said.
