"If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem."
Assuming you're running Windows XP right click your Taskbar and under Toolbars make sure that Quick Launch is checkmarked.

Icons missing were all quick start icons, with the exception of messenger which is in the lower right-hand corner. It's gone, too. I immediately ran several programs: CCleaner, CWShredder (found and fixed CWS.Msconfig), Adaware and Spybot, all in safe mode.
Another odd thing that's been happening recently is a box popping up before the the log-in box comes up, saying "A duplicate name exists on the network."
Any thoughts?
