...well not completely. Security company FireEye and spam-tracking service SpamHaus seem to have shutdown "Grum". A spam botnet believed to be responsible for 18% of the world's spam. Spam is what happens when you don't know how to use a computer and click on free Viagra or 10$ Rollex watches. Then your computer gets infected with a malware and then you have to ask your little brother or friend to come fix your computer.
