Hello,
I think I have a Rootkit infection. When I try to remove it with anti-virus software I get the "blue screen of death" after removing it. To get my computer to work I then need to do a system restore back to when the virus was installed. Help!!!

When I tried to run the DDS program I get a lot of garbage characters. In the message it states "This program cannot be run in DOS mode."

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

I tried to run both GMER and DDS. GMER ran before but it won't run anymore. DDS gives an error that it cannot be run in DOS mode. Help!

Hi,

I think I have a Rootkit infection. When I try to remove it with anti-virus software I get the "blue screen of death" after removing it.

What program detects infection? Does it show its name and location?

I haven't had a program name a particular infection but if I run SuperAntiSpyware and delete the cookies my system won't run the next time I start the computer. I get a "blue screen of death" and it just tries over and over to reboot. The only way I can get the computer to run again is to do a system restore to before I ran SuperAntiSpyware and removed the cookies.

Hi,

Removing pure cookies shouldn't result into unbootable system. Could you run a scan with SuperAntiSpyware but leaving detected items not fixed? Then let me know what items did SAS find.

Hi,

1. Download TDSSKiller and extract its contents into a folder in desired location (i.e. c:\tdsskiller).
2. Execute the file TDSSKiller.exe.
3. Click Start Scan. If threats are found, select skip and click Continue (tool may prompt for a reboot).
4. Post back contents of log file in c: drive root (name should be in UtilityName.Version_Date_Time_log.txt format)

Hi,

Is my system clean?

That's what those logs seem to indicate. Let's run ESET online scanner still.

* Go here to run an online scanner from ESET.
  • Note: You will need to use Internet explorer for this scan
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the activex control to install
  • Click Start
  • Make sure that the option Remove found threats is UNchecked and the option Scan unwanted applications is checkmarked.
  • Click Scan
  • Wait for the scan to finish.
