Anyone have some more details on how this is installed on the end-users systems?

Greetings Roger,
Thank you for trying to be helpful in this way. I have ESET Smart Security 4 and it is Warning me that this file is a threat; referring to it as "a variant of Win32/Toolbar.Zugo potentially unwanted application" and offers three (3) actions:
1. Clean
2. Delete
3. No Action

I am a carpenter who has absolutely no clue about this type problem, but something is causing Outlook to ask for my password and then not accepting it.??? Also in Outlook after be open for an indeterminate amount of time the tool bars across the top will be "blackened out" when my cursor is run across them. Closing out Outlook "cures" the problem for a while but seem to return withing several hours or days???? Have no idea if these problems are related.

Have tried using the reset point at least two (2) times but has not helped yet.

Also C:\Users|Reeder\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\6\34eb986-4e69bee0 is recognized as a threat "a variant of Java\agent.DU trojan"; offering the same three (3) solutions. This particular threat would seem a no brainer with the last word - "trojan". But again I am at a loss as to what should be done.

Thanks for any assistance you might be willing / able to provide.

@Zariah: ToolbarUpdaterService.exe is the updater component of the StartNow toolbar. If you use the StartNow toolbar I would keep the ToolbarUpdaterService.exe file.

@Reeder: I think you should remove the "Java\agent.DU trojan" threat.

Thank You for the information. I will try removing it later today. For me it has been detrimental. It is running when I am playing desktop games such as Win XP Solitare and Chess Master. It is also running when I am on the WEB. I can't find anything good about it. It Eats up a lot of CPU (Pentium 4 3.2 GHz)and RAM. I WAS TOLD (by a tech) THAT IT ALSO NEEDED TO BE CLEANED OUT OF MY REGISTRY. Is this true or false? Thank You Ron

This .exe has given me a real hassle. It caused pagefile spikes to occur every five seconds that used 100% of my cpu and massive amounts of memory. After researching it on the net, I found out that it is bundled with some other "free" software, and not necessary. I first suspended it using sysinternals, and then uninstalled it using the tool contained in the application folder found in program files called Startnow. Fixed!
