    Please your help with a big problem which already destroyed 3 different p.c.'s.
    I'm 100% sure this is caused by a hacker. How is it possible that my computer makes an unwanted and hidden connection with an other computer. As soon as I start up my p.c. the hacker is in full control of my computer even when the internet connection is turned off. Can it be my p.c. sends out some kind of signal without having an internet connection? I know this sounds weird but I've been noticing it many times: - when I'm reinstalling a computer after wiping the hard disks - when installing a brand new computer for the first time - when I start up Linux Parted Magic with the U.B.C.D. The virus, Trojan, back door or whatever can't be detected by any scanner. Please your help!

    1) Are you using a legit Windows DVD when installing. Pirated stuff usually comes with hackers' stuff built in.

    2) Have you tried unplugging the ethernet cable, if you are not using wireless. If you are using wireless, unplug the cable from wireless router to modem. What I do when installing Windows is unplug the ethernet cable, install, then install Win7 SP1. Then I install antivirus, configure Windows firewall, all without connecting to the internet. After making sure that the PC is protected, then I go online and do Windows Update immediately. And I do not surf with the unpatched Internet Explorer while updating.

    3) The normal way to see network connections is to open a cmd prompt with right click, Admin rights. Then typing in "netstat -abn" But if the hackers installed a rootkit, netstat may not show their connection.

    4) Can you explain in more detail what the hackers did? How did they destroy the 3 PCs.
