I recently was attacked by some nasty malware that left my computer a mess. I was able to restore just enough functionality to get back on line. Their are several issues like a DCOM Process Laucher shuting down the computer as well as AXWIN Frame Window: svchost.exe - Application error which says "The instruction "0x0268f7a0" referenced memory at "0x0268f7a0". The memory could not be "written". Also I still am unable to enter safe mode. My PC has C,D and E drives with D designated for OS patches and E which is supposed to be empty but now has what look like some system files in it. Finally the sound does work neither via speaker nor headphone. I have ran Malwarebytes and Anti Super Spyware. They found some infected objects I missed. But from want I have read, I might now have a rootkit problem. I am interested in learning how to do this myself as I am plan to re-format hard drive and reinstall windows xp pro anyway. I am using this opportunity to learn more about my PC....fixing the my PC seems the best way to learn. Is there a free rootkit software tool that you could recommend.

Is there a free rootkit software tool that you could recommend.

There are many free anti-rootkit (ARK) tools but some require a certain level of expertise and investigative ability to use so they are intended for advanced users or under the guidance of an expert as they are powerful and can be misused with disastrous results. These are a few of the easier ARKS for novice users:However, these will not remove the infection you are dealing with. You can try using the TDSS Rootkit Removing Tool but it may not always be effective.

The DCOM Process Laucher shuting down the computer issue is a symptom of the TDSS/TDL3 rootkit.Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to be used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Although the rootkit was identified and may be removed, your machine has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is hidden piece of malware (i.e. rootkit) which has not been detected by your security tools that protects malicious files and registry keys so they cannot be permanently deleted. Other rootkits can even terminate your by changing the permissions on targeted programs so that they cannot run or complete scans. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

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 "bump" your post or 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.

If you are not in a hurry then posting the required logs and going through the removal process will still be a learning experience.
