I have a computer that is running XP SP3 and I have been getting messages that I am infected with Trojan.Gen.2, I use Symantec and it quarantines it but two days later it is back and it says it found 100+ in my temp folder. I boot in safemode and delete, and all is fine for a few days and then it is back again. Ideas on how to remove it 100%?

Thanks

Hi,

After performing these scans, enter the results in your next post and also update me on the status of the PC.

Note: You may have to perform some or all of the following in Safe Mode With Networking, depending on if you have internet access while in the normal Windows environment.

================================================================================

Download Security Check by screen317 from here or 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.

================================================================================

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
    For instructions with screenshots, please refer to the How to use SUPERAntiSpyware to scan and remove malware from your computer Guide.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all other options as they are set):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the Control Center screen.
  • Back on the main screen, under "Select Scan Type" check the box for Complete Scan.
  • If your computer is badly infected, be sure to check the box next to Enable Rescue Scan (Highly Infected Systems ONLY).
  • Click the Scan your computer... button.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the scan log after reboot, launch SUPERAntiSpyware again.
  • Click the View Scan Logs button at the bottom.
  • This will open the Scanner Logs Window.
  • Click on the log to highlight it and then click on View Selected Log to open it.
  • Copy and paste the scan log results in your next reply.
-- Some types of malware will disable security tools. If SUPERAntiSpyware will not install, please refer to these instructions for using the SUPERAntiSpyware Installer. If SUPERAntiSpyware is already installed but will not run, then follow the instructions for using RUNSAS.EXE to launch the program.
================================================================================

Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
Malwarebytes 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 and double-click on the renamed file to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 and continue.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When 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, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • 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 the database version and your operating system.
  • Exit Malwarebytes when done.
Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

-- Some types of malware will target Malwarebytes and other security tools to keep them from running properly. If that's the case, go to Start > All Programs > Malwarebytes Anti-Malware folder > Tools > click on Malwarebytes Chameleon and follow the onscreen instructions. The Chameleon folder can be accessed by opening the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware).
================================================================================

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • 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.
  • 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 you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Still comes up, it scanned and said it found 2585 issues. And they are all in local settings/temp folder. One is DWH1ad2.tmp. :(

I delete all of them in safemode and I am ok for few hours then it comes back again. I did notice when it is finding them a .exe file is in the temp dir for about 1.5 seconds then goes away and I get 5-6 .tmp files. Then it comes back and repeats. It does this for hours.

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

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