BleepingComputer.com: Multiple sirefef trojan infections.

Hello

I have windows vista Home Premium

earlier today Windows Security Essentials popped up and tole me I had 5 infected file and that I should remove them.

trojandropper: win32/sirefef.n
trojan win64/sirefef.E
trojan win32/sirefef.j
trojan win32/sirefef.P
trojan win32/conedex.A

I followed the prompts however they were not removed.
I noticed that the selection of any link from a google search using Firefox regardless of what it was saw me directed to an random advertising site. I also saw that firefox would open another tab an its own and display an advertising website from time to time.
Windows essentials would pop up and seemingly automatically attempt to deleted these files and fail and the process would repeat itself every 15 minutes or so.

I searched high and low for a solution and stumbled on Hitman and it did seem to remove all of the infections but now trojan win32/sirefef.b has turned up and it wasnt there before.

so thats it for the info I can share with you at the moment.
Any assistance to help clean my machine would be appreciated.

Please follow the instructions in ==>This Guide<== starting at Step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

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.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

I have run as many of the steps as I could and reposted withinformation as requested in the topic in malware removal section


thankyou for your help

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 MR Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
