Hello Everyone,I have being trying to remove malware from my desktop win 7 professional software without any success,except now being able to connect to the internet with google chrome.I have tried the tutorial using Rkill,followed by malwarebytes scan,which found nothing and superspy which did find and remove some virus.I cannot find free software that will do the job and if I buy a program there is no guarantee it will fix the problem.I was hoping some one could suggest a cmd method of removing corrupted registry files,have run system file checker and found corrupted files some of which it cannot repair.My last resort will be to format and clean install win 7 ,but Cant even get into disc management to do that, help would be very welcome

Edit: Moved topic from Win 7 to the more appropriate forum. ~ Animal

Hello and welcome.let's run these first as manual removal can be dangerous.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.



I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Under scan settings, check Posted Image and check Remove found threats
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.
  • Push Posted Image

Man we need to try a Rescue disk.
Please download the Avira AntiVir Rescue System.
alternate download link
Place a blank CD in your burner and double-click on the rescue system package (rescuecd.exe) to burn it to a CD/DVD which you can then use to boot your computer and run a scan. For detailed instructions, refer to the Tutorial for Avira Rescue CD. If you encounter problems running Avira AntiVir Rescue System, you can get further assistance at the Avira Tools Support Forum.
