Hi guys,

My friend installed "WinZip Toolbar". It brought with it SystemFix, one rootkit that was removed by TDSSKiller. After a lot of file renaming, we got rkill to work and then MalwareBytes which cleaned up 10 Trojans and BHO objects.

After a system restart, we ran unhide and are now having only the following problems:

Windows host process (Rundll32) stopped working and was closed
Google redirects on search queries for "MalwareBytes" to ads

We found that Firefox was running a proxy, so we disabled the proxy and that helped with some of problem 2 but it still reoccurs. When we run rkill, we get many errors about explorer.exe having issues. Then rkill completes and the errors stop for a bit until Windows host process (Rundll32) dialog starts again.

If we can fix these two problems, I think this thing will be as good as new. Your help is appreciated and the HiJack This log is below. Thanks -- BleepingComputer.com FTW!

To continue -- I removed:

O2 - BHO: WinZipBar - {50fafaf0-70a9-419d-a109-fa4b4ffd4e37} - C:\Program Files (x86)\WinZipBar\prxtbWinZ.dll

Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps.
===

The HijackThis tool is not ready for the 64 bit operating system. In your case I need to see a DDS Log.
I would remove HijackThis using the Add/Remove Programs list.


Please download and run this DDS Scanning Tool. Nothing will be deleted. It will just give me some additional information about your system.

Posted Image
Download DDS and save it to your desktop from here or here.
Disable any script blocker, and then double click dds.scr to run the tool.
  • When done, DDS will open two (2) logs:
    • DDS.txt
    • Attach.txt
  • Save both reports to your desktop.

Please just paste the contents of the DDS.txt log in your next post.
