ISearch is affecting Mozilla Firefox right?
What's wrong with Internet Explorer? See if SFC can find anything wrong:
Go to Start->Run and type in sfc /scannow and hit OK. Let it scan. If it finds any files missing/corrupted, it may ask for the Windows CD.
Go into Firefox->Tools->Extensions-> and right click ISearch plugin and choose Uninstall.
Go to C:\Program Files\Mozilla Firefox\searchplugins\ folder and delete these files:
isearch.gif
isearch.src
Open up prefs.js in Notepad and edit these lines:
user_pref("browser.search.defaultenginename", "ISearch"); -->
user_pref("browser.search.defaultenginename", "Google");
user_pref("browser.search.selectedEngine", "ISearch"); -->
user_pref("browser.search.selectedEngine", "Google");
Delete this line in prefs.js file
user_pref("keyword.URL", "http://www.isearch.com/?q=");
Your log is clean.
