Infected with Rootkit.TDSS. Apparently removed using Combofix. I ran it from D:\ instead of desktop. Computer seems to be running fine now but I can not open any files that were in root d:\ These files include .doc, .jpg, .pdf, .txt files. The folders in d:\ are ok and files inside the folders are still fine and can be opened. Everything else is also ok.

1) Why is it important to run Combofix from the desktop? (it is instructed but I have not come across any explanation for it).
2) Double clicking on the mentioned files opens them but with various error messages. txt files open with garbled characters.
3) I have Credant mobile guardian running on the machine.

Thanks for comments and ideas.

ComboFix (CF for short) is intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Please read Combofix's Disclaimer. When CF is run without trained assistance, it can no longer be considered a "safe" tool. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

***************************************************

1) Why is it important to run Combofix from the desktop? (it is instructed but I have not come across any explanation for it).

At the request of the author, information about the inner workings of CF are not available for public view. That's the decision of the creator and we will abide by that decision. However, I will say that every instruction given by Staff here at BC is done so for the benefit of the user. Disregarding any detail can have serious consequences.

You will need to post a DDS log in the HJT forum so that a HJT Team member can take a look at your situation and see if the damage can be reversed.
Please read the information about getting started. After you have followed the steps in that guide, I would like you to start a new thread HERE and include a link to this thread.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient. It will likely take 12-14 days for a reply due to the backlog of help requests.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.


To avoid confusion, I am closing this topic.
