I have picked up a case of virus/trojan and need help, please.

Operating system is Vista Home. Latest service pack with updates in the last 90 days.

Very soon after this infection I attempted to run my Webroot Anti-virus which was made inoperable and gave me a window saying it was busy and couldn't scan. Subsequent attempts to run Webroot puts it in an eternal "Loading...please wait" mode which it doesn't recover from.

I then downloaded HijackThis and ran that, the program attemped to display the log window but was shutdown and is now inoperable. I now get the Windows warning "Windows cannot access the specified device, path, or file. You may not have the appropriate persmissions to access the item." when I try to start it again.

In my task manager there is a new process that will not shut down with "End Process". It is labeled "258168612:3685260528.exe" and also approximately 10 iexplore.exe processes running.

I was able to delete approximately 5 files associated with Blackbird.exe. I have also deleted a file in c:\windows called "258168612" that reappears upon restarts.

I have run Windows Defender with some success. Defender has found Trojan:Win32/Sirefef.O 4 times and has encountered and error when trying to remove it. Defender has also found Trojan:Win32/Sirefef.I one time and has "Succeeded" in removing it.

In Defender/Software Explorer/Currently Running Programs there is a file labeled "potentially unwanted". Its details are:
File Name: 258168612:3685260528.exe
Auto Start: No
File Path: C;\\Windows\258168612:3685260528.exe
Process ID: 1180
Classification: Potentially unwanted

That is all the information I have been able to gather thus far. Thanks in advance for the help.

With the information you have provided I believe you will need help from the malware removal team.
Please make sure that you read the information about getting started first.
Then start a new thread HERE and include or required logs.
Including a link to this thread will be helpful.

Good luck and be patient. Help is on the way!

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic426378.html 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 MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in 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 MRT 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 MRT Team members are EXTREMELY 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 MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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

To avoid confusion, I am closing this topic. Good luck with your log.

Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
