pls help me..my address bar was disabled by virus

[galunggong23]

I inserted a removable disk to my pc, when i scanned it with my nod32 antivirus, no virus was detected.  However, when double clicked the icon a dialog box opened showing "Winzip Password".  When i checked my address bar it was already disabled.  Spybot then asked for allow change of value or deny.  I chose deny and the log showed this msg.

3/31/2008 12:34:02 PM Denied (based on user decision) value "AutoRun" (new data: "C:\WINDOWS\pc-off.bat") added in Command processor!
3/31/2008 12:34:03 PM Denied (based on user decision) value "UserInit" (new data: "userinit.exe,bar311.exe") changed in Winlogon!

I think this is a new virus.  I am hoping for your advice regarding this.  Please help me.  Thanks
