Downloaded TDSS and put it on the desktop but it won’t run. Any ideas?

..ask the Freeper who used to consult for Norton and Avast’s rootkit-hunting system. Some of the freepers were correct but how they said it were wrong.

No, it worked for me on the desktop. Let me search a bit.

I assume you unzipped it and doubled-clicked on

Disinfection of an infected system TDSSKiller.exe?

From http://support.kaspersky.com/viruses/solutions?qid=208280684

Download the file TDSSKiller.zip and extract it (use archiver, for example, WInZip) into a folder on the infected (or potentially infected) PC.

Execute the file TDSSKiller.exe.

Wait for the scan and disinfection process to be over. It is necessary to reboot the PC after the disinfection is over.

Let’s confirm you are running it properly. Is this a 64 bit system? That would be a problem.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky’s website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
•Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
Vista/Windows 7 users right-click and select Run As Administrator.

•If TDSSKiller does not run, try renaming it.

•To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.

•Click the Start Scan button.

•Do not use the computer during the scan

•If the scan completes with nothing found, click Close to exit.

•If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.

•Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.

•A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).

Rename it to something random with extension ".com" (rootkit blocks execution of many programs).

From the manual: 2.Before you can run TDSSKiller, you first need to rename it so that you can get it to run. To do this, right-click on the TDSSKiller.exe icon that should now be on your Desktop and select Rename. You can now edit the name of the file and should name it a random name with the .com extension. For example, 123.com or 23kjasd123.com.
