I believe my PC is infected with something. It started a while back when I had a pop-up of a very unconvincing XP security tool. I did a websearch and discovered a number of people where having this problem and the best solution was Hitman Pro 3.5.

This did remove the XP security tool, and a scan with Spybot Search and Destroy discovered a backdoor trojan that Spybot sucessfully removed. I thought my problems where over, but now the problem seems to have problem has gotten worse.

Currently I use Norton Anti-virus, Hitman Pro 3.5, Spybot Search and Destroy and Malwarebytes' Anti-malware.

When I use Malwarebytes' Anti-malware it discovers that I have two Trojan.Fraudtools (00092501.exe and 00092515.exe). If I attempt to removes these with Malwarebytes I'm asked to restart windows and upon doing so I get a blue screen.

I can restart windows normally if I revert to my last good configuration that worked but this doesn't solve the problem.

Here is the last Maleware log I took, I also have Hijackthis on my system if you want me to get a log from that.

OS: Windows XP Pro

Lately my PC has become infected with a number of viruses. It started with a fake Secuirty tool called 'XP Secuirty Tool'. Using Hitman Pro 3.5 and Spybot I thought I got rid of it until a few days ago when more started to appear on my PC, with Hitman picking them up and removing them. The last one I that appeared I think was XP Defender and caused my PC to lock.

After restarting and running Malwarebytes Anti-maleware I recieved the log shown below.

I was then asked to restart my PC to complete removal and now when I start up my PC I get a BSOD after the Windows XP loading screen, unless I start in Safe Mode or Use the last good configurations that worked.

Does anyone know what happened? Is my registry screwed?

One of the identified infections is related to HelpAssistant, a Mebroot variant which infects the Master Boot Record. More specifically, this malware overwrites the Master Boot Record of the hard disk with its own code and stores a copy of the original master boot record at another sector while using rootkit techniques to hide itself. Mebroot uses the Remote Desktop (part of Windows) to get full access to the computer and when a remote session is active, it gets managed over the Helpassistant account. The newer variants in particular can be very difficult to remove. For more specific details about this infection, read:Mebroot is contracted and spread through ads in spam e-mail attachments, by using shared folders on peer-to-peer networkes, using Torrents, and via drive-by downloads when visiting porn and malicious websites using browser exploits.

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 log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help". If you cannot complete a step, then skip it and continue with the next. In Step 7 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 Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response 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 Malware Response 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 Malware Response Team.

Please be patient. It may take a while to get a response because the Malware Response 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 posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response 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 Malware Response Team member is already assisting you and not open the thread to respond.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/315011/helpassistant-problem/ 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.

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