My computer recently became overloaded with spyware. Through the combination of defender/adaware/spybot I was able to eliminate most of the spyware however a browser hijacker, zlob.downloader, is not able to be removed. Spybot is capable of removing the spyware, but when IE is restarted it becomes detectable again. My hijack this log follows.

Hey Twixx, welcome to BleepingComputer.

It is a good idea to print off these instructions - they will be needed later when internet access is not available. You may also like to save these instructions in word/notepad to the desktop where they can be easily found for the same reasons as above. It is important that you complete the following instructions in the correct order, and also that you don't miss anything out!

You are missing one important program on that computer: An antivirus.
This is somewhat suicidal in today's digital world.
You need to install an antivirus program as soon as you can and run a complete scan of the computer.
AVG, Avira OR Avast are good FREE antivirus.
Never install more than one antivirusscanner or firewall on your system! Several together can give problems and decrease the reliability of it seriously!
Zonealarm, Agnitum Outpost Free OR Kerio are FREE firewalls.
Understanding and using firewalls

I see you have Viewpoint installed.
Viewpoint Manager is considered as foistware instead of malware since it is installed without users approval but doesn't spy or do anything "bad". This will change from what we know in 2006 read this article: http://www.clickz.com/news/article.php/3561546
I suggest you remove the program now. Go to Start > Settings > Control Panel > Add/Remove Programs and remove the following programs if present.
  • Viewpoint
  • Viewpoint Manager
  • Viewpoint Media Player
* Download smitRem and save the file to your desktop.
Doubleclick it and choose install. This will create a new folder on your desktop with the name smitrem.

* Please download Ewido anti-malware ; it is a 30 day trial version of the program.
  • Install ewido security suite
  • Ewido will automatically run at the end.
  • The program will now open to the main screen.
  • When you run ewido for the first time, you may get a warning "Database could not be found!". Click OK. We will fix this in a moment.
  • You will need to update ewido to the latest definition files.
    • On the top row of the main screen click update.
    • Then click on Start Update.
  • The update will start and a progress bar will show the updates being installed.
    (the status bar at the top will display ("Update successful")
If you are having problems with the updater, you can use this link to manually update ewido.
ewido manual updates
Don't run it yet.
* Please download ATF Cleaner by Atribune.
Do not run it yet.

* Open hijackthis, click 'config' (bottom right)
Choose the tab 'misc Tools' on top.
Choose 'delete a file on reboot'
In the field, copy and paste next:

C:\WINDOWS\SYSTEM32\wingdm32.dll

Click open.
Hijackthis will tell you that this file will be deleted on next reboot and if you want to reboot now.
When asked if you want to reboot now, say No.
