Before doing anything if you have not already done so, you should back up
all your important documents, personal data files and photos to a CD or DVD drive as some infections may render your computer unbootable during or before the disinfection process
. The safest practice is not to backup
any files with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.
Please follow these instructions: How to remove Google Redirects or the TDSS, TDL3, Alureon rootkit using TDSSKiller

instructs you to scan your computer using Malwarebytes Anti-Malware
. Don't forget to check for database definition updates
through the program's interface (preferable method
) before scanning.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.
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.
- After completing the scan, 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.
-- Some types of malware will target Malwarebytes Anti-Malware and other security tools to keep them from running properly. If that's the case, please refer to the suggestions provided in For those having trouble running Malwarebytes Anti-Malware
as you may need to rename it or use RKill
: If you ran or want to run ComboFix on your own due to malware infection, please be aware that using it is only one part of the disinfection process. Preliminary scans from other tools like DDS
should be used first because they provide comprehensive logs with specific details about files, folders and registry keys which may have been modified by malware infection. Analysis of those logs allows planning an strategy for effective disinfection and a determination if using ComboFix is necessary.
Further, when issues arise due to complex malware infections, possible false detections, problems running ComboFix or with other security tools causing conflicts, experts are usually aware of them and can advise what should or should not be done while providing individual assistance. When false detections are identified, experts have access to the developer and can report them so he can investigate, confirm and make corrections. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment.
