A botnet is a network of "zombie" computers infected with malware that enables cybercriminals to commit undetected fraud and other harmful acts.
To help disrupt an emerging botnet, the Microsoft Digital Crimes Unit (DCU) recently took legal action against cybercriminals who were responsible for distributing 500 different strains of malware with the potential for targeting millions of innocent people.
Microsoft discovered that retailers were selling computers loaded with counterfeit versions of Windows software embedded with harmful malware that allowed criminals to steal people’s personal information and send fake scam emails and social media posts to victims' family, friends, and coworkers.

Recently I got a strange phone call from "Windows Australia". The caller told me that my computer had sent error messages to "Windows" and the caller wanted me to give them remote access so they could read the reports on my computer.
It did not happen. -Since I use dial-up it could not happen anyway, since the phone and the computer can not be "on" at the same time.
However, what were they after??
what are the Windows program infected? what computers aren't infected?
