Long Story: I am working on a friends computer (as a volunteer) and they obviously had a rootkit intection: multiple command window pop-ups, fake anti-virus screen, etc. They had taken the computer to a professional (?) who not only could not fix the rootkit problem but made things worse by adding a small 5 gig partition to the harddrive, copying the C: drive to that and then attempting (maybe) to clean the C: drive from the new partition (on this computer called H). Now the computer starts from H: and not from C: and the partition is nearly full. The first thing I did was run Smitfraudfix and then installed and ran Malwarebytes. I also installed and ran Spybot S&D. These found but apparently did not clean a W32.tdss.rtk. Thinking that the best thing to do was to try to get the computer to restart from C:, I went to Disk Management but could not see either partition. Finding that this was also rootkit behavior I attempted to clean it by running McAfee's rootkit removal beta. This found and renamed (.REN)vsfocexnossiem.sys in the system32/drivers folder. After this I could see both partitions in Disk Management and it showed C: as the System volume and H: as the Boot volume. For whatever reason, Microsoft has decided to use very confusing terms and though it sounds the opposite, the computer is booting from the C: partition but using the System (Windows) files from H:. There seems to be a complete installation of Windows on C: however. I tried to install Recovery Console as described by Microsoft but this would not run. I then slipstreamed a Windows XP SP2 boot disk and booted from that. This finally got me to recovery console (whoohoo!) and asked me which of the two installations, C: or H:, I wanted to log onto (whoohoo!) and I chose C: and ran bootcfg /scan and it found only one Windows installation, H: (doh!). So, no joy there. Thinking that I had no choice but to do a Repair install from my slipstreamed disk I started the Windows setup and expected to get to a window that told me that I had two instances of Windows but got "Setup cannot find a previous version of Windows" etc. (doh! squared). My last trick will be to replace the system software, sam, etc. from the windows/repair folder and hope that that fixes thing but BEFORE I DO I would like to find out if a rootkit or its remains are stopping my repair install. Can a rootkit cause repair install to not be an option? Is there scanning software that will look for viruses in C: if I am running from H:?
