Trying to figure out what to do. I have a 64bit eMachine desktop, with Windows 7 home on it.

I believe it was infected with some kind of rootkit last fall, when it was still practically new. I haven't used it much at all since then, and have kept it totally offline. Because I could not find a way to stop remote computers from connecting to it at the time, changing my system settings, disabling my firewall, etc. I tried formatting the C: partition several times.

(but not the recovery partition, which has no letter). Once I even used the boot utilities on my XP cd from my previous computer, and just formatted over it. That didn't make the problem go away either. As it is now, if I try to restore it to the factory state from the recovery partition, the problem re-installs itself right along with the OS.

The original recovery disks I created no longer work; if I try to use those, I get an error message, that it's looking for some network drive that's not available. (Sorry, I don't remember the exact error, but it was something like that.) Next, I ordered new disks from the manufacturer, and when I explained what was happening, they told me that I had to 'securely wipe' the drive first; something about writing over it with 1's and 0's, and making sure that any malware was really gone, before I could install the new disks they sent. That is, reinstalling the disks alone would not fix the problem. So, now I'm trying to figure out how to wipe out this drive, re-partition and format it. So I can try to install the new disks the manufacturer sent, so I can start using it again.

(The computer I'm using now, is ancient. And about to die) There are so many tools available with this functionality, I'm feeling confused. And really just chicken to attempt anything, unless I'm sure I'm going about this the correct way.

A friend told me to try something called Ultimate Boot CD - it has a million tools on it. I'm having trouble figuring out which tool to use first, as well as finding instructions on how they all work, etc. Before I do anything, I just want to make sure I'm going about this the correct way. Pole chudes game. If it is a rootkit, will WIPING the drive, and reinstalling the new disks actually take care of the problem? I don't care about saving anything from that computer at this point, so that's not an issue. I'm mostly afraid that if I do something wrong, or if the rootkit won't allow itself to be erased for some reason. That the whole thing might be unbootable if I do something wrong.

Sorry to ask so many questions, but. The more I try to figure this out myself, the more confused I seem to get.

Any help at all would be greatly appreciated. Hi, You can use the tools from the Ultimate Boot CD to erase everything on the HDD and then start clean using the recovery disks you have. Boot with the Ultimate Boot CD • HDD • Disk Wiping • Active@ Kill Disk Free (Let the computer run until Active Kill Disk opens) • Click OK on the information about the free version • use the up and down keys to select the HD (1:) • press F10 to start the wiping process When the process ends you can restart the computer replacing first the Utimate Boot CD with the Recovery Disk 1 you have.

Wiping the hard drive is in option but have you may be able to save the system by creating a thread explaining the problems you are having etc. You say you had or have a rootkit? There are many talented people here and can assist you by running various programs that will tell you exactly what is wrong etc.
