Printer Spooler
Sdbot.GN creates the file SPOOLSVR.EXE in the Windows system directory. This file contains the code of the backdoor.

apart from being printer related, it's a pain in the ass! aol triggers it, as does microsoft word... It makes me believe my computer has sentience as it starts when my pc boots up. Sometimes it dosen't! It's a wierd one I haven't sussed yet.
According to my Zone Labs Firewall, this program is repeatedly trying to access to the internet. I'm trying to figure out WHY... especially if the executable file is just the "Printer Spooler" that "Alex" and many others say it is. What could a printer spooler want with access to the internet?

Spool32.exe is a 32-bit Windows 95 or Windows 98 component that manages the spooling of print jobs. This process is only executed when this method is selected in the printers configuration properties. This program is important for the stable and secure running of your computer and should not be terminated. But if a process named spool32.exe is running on your computer, you may have been infected with a strain of the Yab.A trojan.
It's a virus on my computer and it forms 'ctxad.exe's, which are considered as viruses by the NOD32 virus scanner.

Best practices for resolving spool32 issues

A clean and tidy computer is the key requirement for avoiding problems with spool32. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the spool32.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
