I googled my problem and found some instructions for scanning and removing this and that. Stumbled here and found a similar post to my problem which involved scanning with ComboFix. Downloaded the instructions to use it.

I got a virus of some sort even though I use AVG 8.5 and Online Armour. It detected threats, but too late as the PC got infected. I've run scans with AVG, Malwarebytes Anti-Spyware and have eliminated most everything (so I think), but there are still some infections according to the scan by ComboFix. I tried to go back a restore point or two, but they failed. I have the wallpaper displayed and about 2/3 of the apps that normally load at startup do load.

I'm running Win XP Home sp3 and when booting the PC Windows loads mostly except for Explorer.exe. I can manually start it via Task Manager, though. Also, Winlogon seems to be infected as it will automatically connect to an address in China. I quickly blocked it from connecting via Online Armour and so far so good with it staying quiet. The last infections according to ComboFix:
c:\windows\system32\userinit.exe
c:\windows\system32\spoolsv.exe
c:\windows\explorer.exe

I can use my PC, but I just don't know if I'm spreading something around or not. I sure could use some help. Thanks in advance.
Oh, I should say that I'm the only user of the PC and I boot straight into my Desktop.

Please note the message text in blue at the top of this forum.

You should not be using Combofix unless instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Combofix was never meant to be used as a general purpose malware scanner like SuperAntispyware or Malwarebytes' Anti-Malware. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. Please read Combofix's Disclaimer.

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 which has not been detected by your security tools that protects malicious files and registry keys (which have been detected) so they cannot be permanently deleted. 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.

Now that your log is 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 member 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.

To avoid confusion, I am closing this topic until you are cleared by the HJT Team. If you still need assistance after your log has been reviewed and you have been cleared, please PM me or another moderator and we will re-open this topic.

Good luck with your log.
