First, be assured that none of the items you listed are in any position to cause system problems - they are strictly leftovers from what you had. But we should be able to remove them.
Open Control Panel
, then open Internet Options
(or from the IE 'tools' menu, select 'Internet Options').
On the General
tab, click on "Delete Cookies", then OK. Then click on "Delete Files" and OK.
Configure Windows to enable viewing of Hidden and System files
Open 'My Computer', then the C: drive:
Navigate to the "C:\WINDOWS\" folder. Find and delete cfgmgr52.ini
Navigate to "C:\Documents and Settings\Default User\Local Settings\Temp\". Find and delete ExtractDLL.dll
Navigate to "C:\WINDOWS\system32\config\systemprofile\Local Settings\Temp\". Find and delete ExtractDLL.dll
, and dkt8F.tmp
If you still have EWIDO installed, run a full scan with that again, being sure you have it updated first. Then let me know if you had any problems with the above and what if anything Spyware Doctor is still finding.
