Hijack This Entries

[homer]

i did a Hijack This scan, and i came up with a few entries that were previously not there. they are as follows...

R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = http://go.microsoft.com/fwlink/?LinkId=69157
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Default_Search_URL = http://go.microsoft.com/fwlink/?LinkId=54896
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Page = http://go.microsoft.com/fwlink/?LinkId=54896
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Start Page = http://go.microsoft.com/fwlink/?LinkId=69157

O9 - Extra button: (no name) - {e2e2dd38-d088-4134-82b7-f2ba38496583} - %windir%\Network Diagnostic\xpnetdiag.exe (file missing)

O9 - Extra 'Tools' menuitem: @xpsp3res.dll,-20001 - {e2e2dd38-d088-4134-82b7-f2ba38496583} - %windir%\Network Diagnostic\xpnetdiag.exe (file missing)

O11 - Options group: [INTERNATIONAL] International*

(an added note, i use firefox, and my homepage has always been google.ca, i would just like to know if i can delete these entries. i also believe that these entries have been added since i upgraded to the newest IE.)

i would like to know if i could safetly delete all these entries.

nevermind, i just set up a system restore point and deleted all of them. so far, nothing has happened.
