Howto remove all kind of malware, rootkits, trojans and virusses

Best way to clean malware, rootkits, trojans and virusses (I call it malware from now on) is to backup your data, scan your data with another computer, remove your partition, reinstall Windows, install a virusscanner, update your Windows and put you data back. This is the safest method and I allways recommend this to people.

But if you don’t want to reinstall everything you can follow this steps to get a infected pc clean.

  1. Go to http://support.kaspersky.com/viruses/rescuedisk/main?qid=208286083 and download the USB util and the Kaspersky Rescue Disk 10 image
  2. Create a bootable USB disk with the USB util. You also can burn the ISO to a CD
  3. Boot from the USB/CD
  4. Make a network connection (I recommend using a network cable)
  5. Update the virus definitions
  6. Select all options and  do a full system scan. This can take about 1,5 hour. Maybe longer if you use a slow disk/pc
  7. Clean all the malware
  8. Exit the rescue disk and boot windows
  9. Now download Kaspersky TDSSKiller @ http://support.kaspersky.com/faq/?qid=208283363
  10. Install the TDSSKiller software, scan the pc and remove the rootkits. It is almost impossible to clean a rootkit with a standard virusscanner. And because of some rootkits you can’t install drivers so you can’t load an antivirus real time protection.
  11. Now install a virusscanner. I recommend MS Security Essentials. This is a free antivirus software.
  12. Update the antivirus (this can take 45 min the first time so please be patient) software and do a full scan.
  13. Now download and install Malwarebytes Anti-Malware and do a full system scan.
  14. Update your Windows true windows update (and turn automatic updates ON!), update your browser, update Java and Flash or remove it.

Now your pc is clean of almost any type of malware and ready to protect it for new malware. All steps together takes almost 6 hours of scanning. So maybe reinstall your operating system is always the best option 😉

This steps helped me to clean a very bad infected laptop that had not any antivirus realtime protection installed. If this steps also helps you to fix a infected pc please leave a comment below or buy me a beer (see widget on the right).
