KidoKiller can clean your computer if it is infected with the network worm Net-Worm.Win32.Kido.The network worm Net-Worm.Win32.Kido (aka Conficker, Downadup ) blocks access to most antivirus sites (for example, mcafee.com, kaspersky.com and etc) and prevents activation of a Kaspersky Lab product (the user keeps receiving error messages).Simply double click it to run, although you might need to right click and "Run As Administrator".
