BleepingComputer.com: Spooler subsystem app has encountered a problem and needs to close

The computer that I am running is a Dell with XP Pro, SP3
I have a USB HP LaserJet 1022 and a networked Brother HL 4040-CN set up and connected to this computer.
When I boot the computer I get the evil message: "Spooler subsystem app has encountered a problem and needs to close." Subsequently I cannot print or add printers, etc.
I have found Microsoft's article Q324757 about this topic. I do all the steps and it fixes the issue. After a couple of weeks, the issue comes back. This is the forth time it has happened. This is my boss's computer so I never see anything that may trigger it. I have ran a virus scan with Antivir, a Malwarebytes full scan, and a Hijack This scan and everything comes up clean. I have also cleaned up in MSconfig. I have gone to the printers' websites several times and grabbed the most recent drivers so I am not using the same drivers over again.
Everything else seems to work as normal with the computer. Short of reloading Windows, is there anything else I should try? Thanks for your help.

Hello

Because you have a log posted here: http://www.bleepingcomputer.com/forums/topic226145.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond. Please be patient. It may take a while to get a response but your log will be reviewed and answered as soon as possible

To avoid confusion, I am closing this topic. Good luck with your log.

If you are still experiencing this issue once you have been declared clean, send a PM to a moderator to reopen this thread.

Regards,
Andrew
