Compaq Presario 900 laptop with AMD Athlon 1.6 Ghz processor, 38 GB HDD, 1 MB Ram running 32bit XP SP3. Was not booting when I got it from a friend who needed help in recovering files about a year ago. I repaired the MBR with a utility called testDisk, fixed disk errors with WinXP chkdsk and scanned it with multiple antivirus programs and cleaned several viruses. I recovered my friend's files. A few of months ago I pulled it out again and loaded Avast(free) for virus detection an SyGate Personal Firewall. Ran IOBit ASC, defragged, brought XP up to date with Windows Update, updated drivers and bios from HP's website. It was still running painfully slowly and the CDRom would not recognize any media. I fixed a problem with the hardrive reverting to PIO mode which helped somewhat. Uninstalled .Net and uninstalled unneccessary programs (HDD now 15 GB used, 25 GB free) Got messages from Avast that it was blocking attempts to access malicous websites (206.253.173.182 and 75.153.176.1). I isolated it from my network.I started researching bootkits, booted to safe mode and used Kaspersy TDSSkiller to remove "Virus.Win32.ZAccess.C" and "Backdoor.Multi.ZAccess.gen" associated with cdrom.sys and the cdrom service. On successive scans TDSSkiller cleaned several files(eg IDriverT, WMDM PMSP Service) logs attached. Malware Bytes scan cleaned PUM.Hijack.Startmenu from HKeyCurrentUser. I ran Combofix which reported "You are infected with Rootkit.ZeroAccess! It has inserted itself into the tcp/ip stack. This is a particularly difficult infection." and a little later "Rootkit is detected". Be patient as this may take some moments". I used Combofix to load the "System Recovery Console" but results were the same. There was a dramatic improvement in the overall speed and responsiveness of the system, but a couple of days later when I connected to the internet, I got another Avast blocked website access message. Combofix will run for 4 or 5 minutes and then freeze after the second message without finishing stage 1. The only way out is to hold the power button for 5 sec to power off. In Safe Mode the HDD indicator light stays on solid, in regular mode HDD activity ceases. I have left it that way as long as 36 hours. The cursor is still active and clicking on Combofix's "AutoScan" Dos window changes the top border from grey to blue, clicking anywhere else causes it to turn grey again. The cursor turns to an hourglass if I move it over the taskbar.Kaspersky TDSSkiller, McAfee Rootkit Remover find nothing, Trend's RootkitBuster fails to load, FSecure Blacklight reports several processes hooked by wpsdrvnt.sys which GMER identifies as belonging to the SyGate firewall. Fport and TCPView don't show anything obvious to my (admittedly untrained) eye. HJT log (safe mode) attachedI have used Defogger to disable CD Emulation, but DDS.scr does not finish. It stops after generating about 40 # characters similar to Combofix, my process monitor indicates 100% disk activity but the hard drive led is off and the HDD has idled down. If I watch them in Process Monitor DDS seems to hang at the MBR.dat stage and Combofix at the FindMBR.3XE stageI ran rKill (no processes reported terminated) then GMER as indicated, log attached. Tried ddr.scr again, same result. HJT log file attached.Suggestions?

Hello and Welcome to Bleeping Computer!!

My name is Gringo and I'll be glad to help you with your computer problems.

I have put together somethings for you to keep in mind while I am helping you to make things go easier and faster for both of us

  • Please do not run any tools unless instructed to do so.
    • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.
  • Please do not attach logs or use code boxes, just copy and paste the text.
    • Due to the high volume of logs we receive it helps to receive everything in the same format, and code boxes make the logs very difficult to read. Also, attachments require us to download and open the reports when it is easier to just read the reports in your post.
  • Please read every post completely before doing anything.
    • Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.
  • Please provide feedback about your experience as we go.
    • A short statement describing how the computer is working helps us understand where to go next, for example: I am still getting redirected, the computer is running normally, etc. Please do not describe the computer as "the same", this requires the extra step of looking back at your previous post.
NOTE: At the top of your post, click on the Watch Topic Button, select Immediate Notification, and click on Proceed. This will send you an e-mail as soon as I reply to your topic, allowing us to resolve the issue faster.

NOTE: Backup any files that cannot be replaced. Removing malware can be unpredictable and this step can save a lot of hartaches if things don't go as planed. You can put them on a CD/DVD, external drive or a pen drive, anywhere except on the computer.

NOTE: It is good practice to copy and paste the instructions into notepad and print them in case it is necessary for you to go offline during the cleanup process. To open notepad, navigate to Start Menu > All Programs > Accessories > Notepad. Please remember to copy the entire post so you do not miss any instructions.

Security Check

  • Download Security Check by screen317 from here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.


  • push the "windows key" + "R" (between the "Ctrl" button and "Alt" Button)
  • please copy and past the following into the box
ComboFix /nombr
  • click ok

copy and paste the report into this topic for me to review
