Who knows what this daemon does when it run? I don't know why but it takes the whole RAM and basicly freeze the computer. The whole thing located in /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/HIServices.framework/Versions/A/Resources/qtimageserver

I was wondering if it's a virus because before never had this kind problems. I use 10.3.4 on PowerBook Al 1.25. Any comment or suggestions are welcome.

It sounds like a image displaying service. It's almost certainly not a virus. Try disabling it, or quitting it when your machine starts up, remove login items (one might be launching it), I don't see it running on my machine.

I've had that running on my machines before. It's not a virus. But I don't know what it is... usually it just goes away on its own. But it does what you describe, sucking up available ram and processor time.

A quick google search, I think it might have something to do with prebinding applications as seen in this Mac OS X Hints thread.

I certainly hope you wouldn't give a virus the root privileges it would need to get into your System folder.

Anyway, it's a private Apple daemon. As far as I can gather, it appears to be used in creating icon previews in the Finder. It probably does some other stuff too, but Apple hasn't bothered to explain what they are. So it's not malicious. If it's causing you grief, odds are it's symptomatic of something.

Also, by all evidence, it has nothing more to do with prebinding than any other application. That MOSXH thread was just about somebody whose prebinding on the program was screwed up.

Well, I still don't know what it's really does, but it runs under my admin name, not a root and it starts after I login automaticly, of course I tried to revove the whole startup items from system, but it looks like a system thing that slow down CPU so much that it is impossible to work for 5-8 minutes after startup. I decide to reinstall the whole system because didn't find where is the problem, of course it's was really simple to kill via Terminal, but after this all applications starts really slow and system works really slow. Well, anyway it's kind strange because I didn't install any new software and didn't change any system preferences, it's just happend on their own. I've looked system cron and didn't find anything related to this deamon as well. Really strange thing.

Have you tried the usual troubleshooting techniques (fsck, repair permissions, create new user to see if problem is in preferences)?

Also, do you have icon previews on in the Finder? Because that's the one thing I'm fairly sure it does.
