无法删除钥匙串

我的钥匙串中有一个Sophos钥匙串，这是一个杀软安装的，卸载掉这个杀软后，钥匙串中有残留，为只读文件，然后怎幺都删不掉，重新安装上这个杀软并执行删除时，提示修改需要密码，输入密码居然无效，有没有什幺办法能强行删除，谢谢！

从国外论坛找到的答案，已经成功，主要是找到/Library/Preferences/com.apple.security-common.plist删除其中的sophos部分，它会提示你只能另存，选择另存，然后更改扩展名为.plist，把它拖至/Library/Preferences/目录，选择覆盖。即可原文如下——————————Tofixthisyouhavetomanuallyeditthefile/Library/Preferences/com.apple.security-common.plist,asroot,anddeletethecorrespondinghardcoded<dict>...Sophos...</dict>entryinthere.Greatcaremustbetakenbecauseyoucantotallyscrewupyoursystem(-keychain)ifyouleaveanyerrorsinsidethis.plistfile.Thesectionthatneedstobedeletedlooksasfollows:<dict><key>DbName</key><string>/Library/SophosAnti-Virus/Sophos.keychain</string><key>GUID</key><string>{someUUIDstringhere}</string><key>SubserviceType</key><integer>6</integer></dict>Uponsave,thereshouldnolongerbeany"Sophos"entryinKeychainAccessorasoutputofsecuritylist-keychains.Iusedvimanddeletedtheoffendinglinesas(sudovim/Library/Preferences/com.apple.security-common.plist)butyoumayuseanytextorplisteditoryoulike-Ifranklydon'tknowwithoneisthemostaccessible(recommendationswelcome).
