So after fighting a 2 day long battle against these bloody downloader trojans I picked up when downloading overclocking software (yes, surprisingly it wasn't XXX content, but a simple overclocking utility), and after not being able to delete the nasty buggers, I'm asking for help (no the world isn't going to end.. yet)

Here's my little (big) log:

Now what I'm assuming are bad are as follows:

O4 - HKLM\..\Run: [BM63df8f5e] Rundll32.exe "C:\Windows\system32\timwotxi.dll",s

Unfortunately, I've tried removing those before with HJT, and they just pop back up, as I cannot seem to be able to delete the darned files themselves from my System32 folder

Some input would be appreciated, even a "DL.. You're screwed"

DL,

A fairly common infection is showing - if that is all there is - we will have you set in no time.

Please download VundoFix.exe to your desktop.

• Double-click VundoFix.exe to run it.
• Click the Scan for Vundo button.
• Once it's done scanning, click the Remove Vundo button.
• You will receive a prompt asking if you want to remove the files, click YES
• Once you click yes, your desktop will go blank as it starts removing Vundo.
• When completed, it will prompt that it will shutdown your computer, click OK.
• Turn your computer back on.
• Please post the contents of C:\vundofix.txt and a new HiJackThis log.

VundoFix V7.0.3

Getting sudden massive amounts of pop-ups argh.. Running AVG again, finding a whole boatload of stuff

We will run ComboFix.

You should NOT use Combofix unless you have been instructed to do so by a Malware Removal Expert. It is intended by its creator to be used under the guidance and supervision of an expert, not for private use. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.


You need to disable your Antivirus and Spybot Teatimer before running ComboFix, as they will prevent it from running.


Please visit this webpage for instructions for downloading and running ComboFix:
A guide and tutorial on using ComboFix

Be sure to install the Windows XP Recovery Console in case you have not installed it yet. <== IMPORTANT

We need Recovery Console because malware damages a lot and causes an instable system - and because of that, it may happen that your computer won't be able to boot anymore. With the Recovery Console installed, there are extra options present to repair whatever malware damaged.
Also, even though you're not infected, the presence of the Recovery Console is a useful feature in case a computer won't boot anymore because of several other reasons. Read here what you can do with the Recovery Console.

Extra note: After you have installed the Recovery Console - if you reboot your computer, right after reboot, you'll see the option for the Recovery Console now as well.
Don't select to run the Recovery Console as we don't need it.
By default, your main OS is selected there. The screen stays for 2 seconds and then it proceeds to load Windows.


Post the ComboFix log.

Er.. I'm on Vista >.>

Sorry, trying to get caught up on other logs.

The link with the tutorial for combofix explains what to do for Vista.
