I'm having problems when I shutdown my computer: everytime it shutsdown, a message from wupdater.exe pops up, and also everytime I connect to the internet, an error message from wupdater.exe comes up saying "data1.dat not found". Can you please help? I have run Adaware and Spybot S&D, and here is my HijackThis log: Logfile of HijackThis v1.97.7 Scan saved at 10:21:44 PM, on 8/01/2004 Platform: Windows XP SP1 (WinNT 5.01.2600) MSIE: Internet Explorer v6.00 SP1 (6.00.2800.1106) Running processes: C:\WINDOWS\System32\smss.exe C:\WINDOWS\system32\winlogon.exe C:\WINDOWS\system32\services.exe C:\WINDOWS\system32\lsass.exe C:\WINDOWS\system32\svchost.exe C:\WINDOWS\System32\svchost.exe C:\Program Files\Common Files\Symantec Shared\ccEvtMgr.exe C:\WINDOWS\Explorer.exe C:\WINDOWS\system32\spoolsv.exe C:\Program Files\Common Files\Microsoft Shared\VS7Debug\mdm.exe C:\Program Files\Norton AntiVirus\navapsvc.exe C:\WINDOWS\System32\nvsvc32.exe C:\WINDOWS\System32\svchost.exe C:\windows\system\hpsysdrv.exe C:\Windows\system32\HpSrvUI.exe C:\Program Files\Hewlett-Packard\HP Share-to-Web\hpgs2wnd.exe C:\Program Files\Hewlett-Packard\Digital Imaging\Unload\hpqcmon.exe C:\HP\KBD\KBD.exe C:\Program Files\Real\RealPlayer\RealPlay.exe C:\WINDOWS\wt\updater\wcmdmgr.exe C:\Program Files\Common Files\Logitech\QCDriver3\LVCOMS.exe C:\Program Files\Logitech\ImageStudio\LogiTray.exe C:\Program Files\Common Files\Symantec Shared\ccApp.exe C:\WINDOWS\System32\ctfmon.exe C:\WINDOWS\System32\rundll32.exe C:\Program Files\hp center\137903\Program\BackWeb-137903.exe C:\Program Files\Hewlett-Packard\Digital Imaging\bin\hpobnz08.exe C:\Program Files\Hewlett-Packard\HP Share-to-Web\hpgs2wnf.exe C:\Program Files\Hewlett-Packard\Digital Imaging\bin\hposol08.exe C:\Program Files\Messenger\msmsgs.exe C:\Program Files\Internet Explorer\iexplore.exe C:\Program Files\MSN Messenger\msnmsgr.exe C:\Program Files\Internet Explorer\iexplore.exe C:\Documents and Settings\Owner\My Documents\Console Games\HijackThis\HijackThis.exe R1 -
