I will try and keep this as short as possible, pc running windows xp i was in the middle of watching a video and the pc crashes (bsod) with an atapi.sys error message, reboot pc and will run for a minute or two then crashes with the same message, rebooted in safe mode and anti virus picks up multiple infections of both rootkit (tdss and mbr) and trojans and is unable to neutralise them all, after much effort i decided to format my other partition on the hard drive and install a fresh copy of xp which i installed kaspersky anti virus (enabling rootkit scan and deep scan etc), malwarebytes, sophos rootkit removal software, combofix and windows defender etc to and scanned the infected partition repairing until showing as clean (other than the combofix message to follow), then copied essential files across to the partition i had been scanning from, combofix was still coming up with a message along the lines of "combofix has detected the presence of rootkit activity and needs to reboot" but was finding nothing, windows defender had picked up on something on the other partition trying to install itself in the start menu but nothing on the new partition, so i stuck all my essential files onto a usb hard drive, deleted partitions on the hard drive and did a full wipe using paragon hard disc manager and installed a fresh copy of xp, installed the basics (drivers and anti virus etc) then ran combofix before going any further, which was now showing as clean, scanned my files on the usb hard drive which came up as clean so copied them back onto the pc, continued to re install software using only the latest installers from the internet from legitimate sites (software such as mozilla, vlc media player, winamp, adobe flash, adobe reader etc) ran windows update until everything was up to date then did another scan with combofix which is again showing the same message as before, mistake here is copying my files across before installing all software on the pc and scanning as now i dont know whether its something i have installed, something i have copied across or a false reading, combofix has found nothing, tdss killer has found nothing, mbr check has found nothing and malwarebytes has found nothing, there is no unusual activity on the comptuter but clearly combofix thinks something is wrong just not sure where i go from here any help would be greatly appreciated

I am moving your post from Malware Removal Logs to Am I Infected...since no logs are attached or inserted. Forum procedure calls for this move.

If you have a Combofix log, I suggest that you post that...in the Malware Removal Logs forum...after reading the procedures detailed in the Preparation Guide, Before Using Malware Removal Tools and Requesting Help - http://www.bleepingcomputer.com/forums/topic34773.html .

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic393776.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.
