Hi
any help or advice appreciated.
Computer working fine 4 days ago,next time I started it up it came up with "exception has been thrown by the target of an invocation".Eventually got rid of this by uninstalling ATI Catalyst Control Centre and then reinstalling.However,sometimes on boot up it started fine but mostly it now freezes at the welcome screen.Started it in safe mode no problem,tried to use system restore both in safe mode and normal and it says" no restore points available".Tried to create one and could'nt.Ran Eset online scanner and it discovered ,healed and deleted win32/delf.ogx also a torrent infection.
I have windows xp home edition,running avg8 antivirus,plus spybot.I am networked to my laptop,so can access internet while trying repair if thats at all useful

Thanks

I suggest running a couple more online scans...to eliminate lingering malware as a consideration.

Please try a couple of these free online scanners to see if anything has slipped by your protection:
(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully)

http://www.eset.com/onlinescan/

http://www.kaspersky.com/virusscanner Scan Only - no removal


If you find that you're infected (or the scan doesn't complete or closes unexpectedly), post in the Am I Infected forum located here: http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/

Post back with whatever results :thumbsup:.

That error message seems to have more to do with MS.NET (which is a prerequisite for installing ATI drivers) rather than the ATI drivers themselves. I would assume damage of some type and remove all installs for MS.NET (via Add/Remove Programs) and then reinstall Version 3.5, SP1 of Net.

Hello and welcome. We are moving this from XP to the Am I Infected forum for scans..

Hello and welcome please run these next. If you have Spybot installed temporarily disable it.
Next run ATF:
Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

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.

Hi and thanks
I actually jumped the gun a little and read a post by "extremeboy"I followed his instuctions and d/l combofix.
All went well and seemed to remove the problem.I then ran a full scan later using malwarebytes and it showed I still had a "trojan.tdss".
I then did exactly as you instructed and everything seems to be fine.I have attached results including the most recent quick scan.
What do you think?
regards
John

This looks good now..
Now 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 backed up, renamed and 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". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
