hello.

I have trend micro office scan running and it keeps (repeatesly) picking up a TROJAN_VUNDO.ATM in C:\Windows\system32\ddabc.dll which it deletes because it cannot repair the file, and it also picks up a file in temporary internet files which it is unable to repair or delete.

In addition, my internet explorer is playing up. I have to repeatedly attempt to open a link in a new window rather then it happening first time; and the little icon picture next to the url it wrong for the site, i.e. the trendmicro icon is there for my google home page. I had ie7 but then add/removed the software, but now i'm left with some base version of ie. am using firefox at the moment.

I scan with ad-aware and its clean, spybot picks up some win32.small.abk(?) and win32.tiny (or mini) but that gets fixed or cleaned.

I'm pretty lost at the moment, and probably making things worst. And i'd rather avoid reinstall windows.

HJT log seems the way to go at this stage but it looks very confusing. I'm trying the housecall application at the moment to see what that picks up...

Ideas, suggestions, and any other help would be awesome

thanks

Welcome to BC chef_32

Please print out and follow the instructions for using "Vundofix". -- If using Windows Vista be sure to Run As Administrator.
  • Click the Scan for Vundo button.
  • Once it's done scanning, click the 'Fix Vundo' button.
  • After running VundoFix, a text file named vundofix.txt will automatically be saved to the root of the system drive, usually at C:\vundofix.txt.
  • Please copy & paste the contents of that text file into your next reply.
Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_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 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 Acan" option is selected.
    • Then click on the Scan button.
  • The next screen will ask you 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 and you may be prompted to restart your computer. (see Note below)
  • 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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

sorry, should have mentioned that everything seems to be running alright apart from IE not opening links in new window when required, and computer is loading up a bit slower then usual. but the key thing is getting IE going like it used to

office scan has not picked up anything lately, will run through other scans again tonight after work.

let me know what you think.

Thanks for the help, its awesome that you guys/girls help people like this.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
You cannot open a new Internet Explorer window

If your computer seems to be slow, read Slow Computer/Browser? Check here first; it may not be malware. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.
Note: If you are not on a local area network (LAN), disable the Workstation Service which creates and maintains client network connections to remote servers and that should also help to speed up your boot time.
