Stop autoloading programs in Windows 7 & 8

Windows 7 and earlier versions

Click Start, type msconfig, and press Enter. This brings up the System Configuration page. Click the Startup tab for a table listing your autoloaders. Now you can uncheck those you don’t want. But first, you have to figure out what each autoloader does. Usually the program’s name makes it obvious. But sometimes the names aren’t clear. If the name isn’t helpful, you can usually get an idea by examining the Manufacturer and Command columns in the table. These will tell you who published the software, and where the file is on your drive (usually the folder for a program you installed).

CryptoWall Ransomware

Overview In late February 2014, the Dell SecureWorks Counter Threat Unit(TM) (CTU) research team analyzed a family of file-encrypting ransomware being actively distributed on the Internet. Although this ransomware, now known as CryptoWall, became well-known in the first quarter of 2014, it has been distributed since at least early November 2013.

The Counter Threat Unit (CTU) at Dell SecureWorks performed an extensive analysis of CryptoWall that involved gathering data from its command-and-control (C&C) servers, tracking its variants and distribution methods and counting payments made by victims so far. CryptoWall is “the largest and most destructive ransomware threat on the Internet” at the moment and will likely continue to grow, the CTU researchers said Wednesday in a blog post that details their findings. The threat has been spreading since at least November 2013, but until the first quarter of this year it remained...
