Sorry for posting in wrong forum.

Re-posted in Virus, Trojan, Spyware and Malware Removal Logs.


Hello,

Using Process explore System PID is now constantly accessing hard drive.

Problem began a few days ago with Firefox being re-directed on a number of sites.


Please help

Thanks

C:\Windows\System32\Drivers\dump_dumpata.sys

DUMP_DUMPATA.SYS is a system driver for managing ATA devices.

Please follow this and post the log:

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Please follow that with this scan and again post the log:

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror <-This version will download a randomly named .exe file (Recommended)
  • Zipped Mirror <-This version will download a zip file you will need to extract first.
  • Disconnect from the Internet and temporarily disable your anti-virus, Firewall and any anti-malware real-time protection before performing a scan so they will not conflict with gmer's driver.
  • Click this link to see a list of such programs and how to disable them..
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • On the right side panel, several boxes have been checked. Please UNCHECK the following:
    • IAT/EAT
    • Drives/Partition other than Systemdrive (typically C:\)
    • Show All <- don't miss this one
    Posted Image
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If GMER crashes or keeps resulting in a BSODs, deselect (uncheck) Devices, Sections, and Files along with the other items mentioned.
-- If you still encounter problems, try running GMER in safe mode.

Thank you. In the instructions for GMER it does suggest disabling your security software so that behaviour is normal.

You have posted a DDS log which is not permitted in this forum and I did not request it.
Mod Edit: Moved DDS post to topic in Malware Removal Logs ~ Hamluis.

I will have to report this to a moderator before continuing.

Hi Mark 1956,

Sorry about the DDS posting but I was following the instructions at http://www.bleepingcomputer.com/forums/topic34773.html.

I'll await your reply.

Easy mistake to make but those instructions are for the Malware removal forum not the "Am I Infected" forum.

As I have not worked on this sight for very long I had better wait to get the all clear from a moderator before giving any further instructions.

OK, but can you at least tell me if you see any problems in the file you asked for?

I have called on a Malware expert to pass comment on the GMER log, hopefully you will not have to wait long for an answer.

Reference: MRL topic at http://www.bleepingcomputer.com/forums/topic438705.html/page__p__2560063#entry2560063 .

Now that you have posted a malware log topic, 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.

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.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic.

Louis
