Hello,
I have a computer infected by a really nasty malware or virus. It has disabled all antivirus/spyware softwares, regedit, msconfig and more. I can't run programs like HJT to get logs.
The infection was first noticable when I got a popup from NOD32 that it had found something and tried to remove it on the fly. After restart the computer was a mess,NOD32 and more disabled.
I have created a UBCD and used that to boot from and scan my harddrive with a number of tools, after that I manged to install Mcafee in safemode. After reboot it reports that services.exe causes buffer overflows.
I'm really stuck, I have nothing of value on the PC but I really want to kill this thing.
Any help appreciated!
Hi,
Download DDS and save it to your desktop from here (http://www.techsupportforum.com/sectools/sUBs/dds) or here (http://download.bleepingcomputer.com/sUBs/dds.scr) or here (http://www.forospyware.com/sUBs/dds).
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. Post them back to your topic.

Please ensure you read this guide carefully and install the Recovery Console first.
The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.
Once installed, you should see a blue screen prompt that says:

Please continue as follows:
Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix, link (http://www.bleepingcomputer.com/forums/topic114351.html)
Remember to re-enable them afterwards.
Click Yes to allow ComboFix to continue scanning for malware.

Close all browser windows and refering to the picture above, drag CFScript into ComboFix.exe
Then post the resultant log.
Combofix should never take more that 20 minutes including the reboot if malware is detected.
If it does, open Task Manager then Processes tab (press ctrl, alt and del at the same time) and end any processes of findstr, find, sed or swreg, then combofix should continue.
If that happened we want to know, and also what process you had to end.
