hi, whenever i start up my PC. The default homepage is set to "scanthenet.com". And it does a lot of other stuff with my IE too. I tried looking at the hijackthis log, but couldn't get what was the problem. Can someone help me with this. Here is my hijackthis log: Logfile of HijackThis v1.97.7 Scan saved at 9:07:15 AM, on 11/30/2003 Platform: Windows XP (WinNT 5.01.2600) MSIE: Internet Explorer v6.00 (6.00.2600.0000) 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:\WINDOWS\Explorer.exe C:\WINDOWS\system32\spoolsv.exe C:\windows\system\hpsysdrv.exe C:\HP\KBD\KBD.exe C:\Program Files\WildTangent\DDC\DDCManager\DDCMan.exe C:\Program Files\Common Files\Real\Update_OB\realsched.exe C:\PROGRA~1\SYMANT~1\SYMANT~1\vptray.exe C:\WINDOWS\PCHealth\HelpCtr\Binaries\MSConfig.exe C:\Program Files\Zero Knowledge\Freedom\Freedom.exe C:\Program Files\MSN Messenger\MsnMsgr.exe C:\Program Files\Yahoo!\Messenger\ymsgr_tray.exe C:\WINDOWS\System32\ctfmon.exe C:\PROGRA~1\SYMANT~1\SYMANT~1\DefWatch.exe C:\PROGRA~1\SYMANT~1\SYMANT~1\Rtvscan.exe C:\WINDOWS\System32\nvsvc32.exe C:\WINDOWS\System32\svchost.exe C:\Documents and Settings\Owner\Local Settings\Temp\Temporary Directory 22 for hijackthis.zip\HijackThis.exe C:\Program Files\Internet Explorer\IEXPLORE.exe R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://www.microsoft.com/isapi/redir.dll?prd=ie&pver=6.0&ar=msnhome R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://www.microsoft.com/isapi/redir.dll?prd=ie&ar=iesearch O1 - Hosts: 66.98.142.169 auto.search.msn.com O1 - Hosts: 66.98.142.169 search.msn.com O1 - Hosts: 66.98.142.169 msn.com O1 - Hosts: 66.98.142.169 www.msn.com O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - C:\Program Files\Yahoo!\Common\ycomp5_1_6_0.dll O2 - BHO: (no name) - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - C:\Program Files\Adobe\Acrobat 5.0\Reader\ActiveX\AcroIEHelper.ocx O2 - BHO: (no name) - {4E7BD74F-2B8D-469E-C0FF-FD60B590A87D} - C:\PROGRA~1\COMMON~1\Real\Toolbar\realbar.dll O2 - BHO: (no name) - {56071E0D-C61B-11D3-B41C-00E02927A304} - C:\Program Files\Zero Knowledge\Freedom\FreeBHOR.dll O2 - BHO: (no name) - {AA58ED58-01DD-4d91-8333-CF10577473F7} - c:\program files\google\googletoolbar1.dll O2 - BHO: (no name) - {FDD3B846-8D59-4ffb-8758-209B6AD74ACC} - c:\Program Files\Microsoft Money\System\mnyviewer.dll O3 - Toolbar: &Zero-Knowledge Freedom - {FA91B828-F937-4568-82C1-843627E63ED7} - C:\Program Files\Zero Knowledge\Freedom\BandObjs.dll O3 - Toolbar: &Google - {2318C2B1-4965-11d4-9B18-009027A5CD4F} - c:\program files\google\googletoolbar1.dll O3 - Toolbar: &Yahoo!

You may have a virus or trojan or worm or adware or some other sort of malware. Run an AV scan, and download AdAware and Spybot, install them, update them, and run them. Delete anything that looks suspicious. Some advise deleting everything because it's all reversible. Also get Spyblaster which keeps a list of bad stuff on your computer and blocks them from being installed (theoretically). Spybot AdAware
