Looking for deals on some Asian shopping sites can be hazardous to your system's security. Avira caught a series of Trojan attacks on 2/24. Terminating the browser I was using was not sufficient stop a redirect virus from installing itself. Opera, IE and Firefox were all being redirected with IE generating spontaneous popups.

My first thought was to check the hosts file with Spybot but it was clear. Malwarebytes found a a Trojan agent and Hijack zone in the registry. Next I did a system scan with Avira and found another Trojan.

I checked the Browsers but they were still being redirected. I uninstalled Opera; ran Superantispyware and threw out all the adware it found. Next I ran CCleaner. And scanned the system with HijackThis but found nothing obvious except a lot of (023) file missing entries because I running 64 bit Windows 7. Anyway the Firefox and IE continue to be redirected. So I reloaded Opera to see if it would be hijacked as a new install. Opera worked. So I finally had a way to search the web.

One of the things I did was to view the page source of one of the redirected pages and discovered a metatag directed to "informationgetter.com". In the process of all this I ran Avira in Safe Mode and discovered a locked file that it couldn't read at C:\Windows\SysWOW64\dmcomposi.dll But I could find no information on this DLL. After this I ran GMER's rootkit an it found nothing.

SoI finally ran Combofix. and the browsers are no longer being redirected. I ran Kaspersky Virus Removal Tool and Microsoft Security Essentials both came up clear. But the dmcomposi.dll is still there and I'm not sure I've really solved my problem. Do anyone know anything about this dll?

Thanks,

Hello having run ComboFix we need to see that and a DDS log.

Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9 which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
Include the info you posted here also.
Skip the GMER step and instead post the ComboFix log you posted earlier.

Let me know if that went well.

OK this new topic looks fine.
http://www.bleepingcomputer.com/forums/topic381860.html/page__p__2149608#entry2149608

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 Malware Removal 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 Malware Removal 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 Malware Removal 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 Malware Removal 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 MRL Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
