If anybody can help and advice with a solution on removing malware from my windows xp sp3 machine

Symptoms what i had are:

System restore unable to use ( greyed out) - but managed to fix by importing registry keys
Unable to enter safe mode ( keep restarting machine ) - managed to fix by importing safeboot registry keys
On login getting error with generic host process for win32 services
System unstable after couple minutes and need to restart machine
MSN mesenger starting even if it not directed to do so
Disabled Symantec Endpoint Protection and cannot open it
Unable to unhide hidden files and folders , same with system protected files ( actually you can unhide it but in couple seconds it hides files again)
It easily infects usb drives how i noticed same problems on other computer that i used my usb drive after i used it on this one.

Anyway , i started a removal process with avast, malwarebytes and spyhunter

avast found a file in windows\system32\wmxperw.exe , it marked it as a rootkit and removed it.
in some time the file came back but was coming back also in other forms.. as :

I have found traces of that in plenty registry keys as well

Finally i bought Prevx 3.0 how it was the only page while i was googleing that came up with definitions about those files

I made a scan and it seemed like it managed to remove it

After that i made a scan with avast again and then he start to find more malwares

All cleaned

Also there is something suspicious with a file Secupdat.dat in system32 folder
Strange thing happening with hosts file , i enabled all monitoring in spyhunter and it came that some changes are happening with it and will i aloud it?
There was a plethora of redirected URL's including most of the Anti-Virus and Security sites that wanted to infiltrate.. i blocked that

there are also strange strings in svchost -netsvcs :

Anyway, with all that protection what i have now active , system stays stable but still everytime when i logon Prevx 3.0 is blocking qxzv5.exe and a
generic host process for win32 services error comes up couple of times.

So i think that still i am not finished with that bastard

Any HELP would be appreciated .

You have a rootkit and you are going to need specialized help

Please read the pinned topic titled "Preparation Guide For Use Before Posting A DDS / HJT 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 Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Removal 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.

The MR team is very busy and it will take awhile to get to your post
Please be patient and good luck

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/298269/cannot-completely-remove-malware-qxzv5exe-still-coming-back/ 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.
