After clearing out the websearch toolbar with a variety of spyware cleaners, I am left with two tmp files in the C:\Windows\Temp folder (WinXP Pro). I have tried (a) deinstalling all strange programmes; (b) deleting through Windows Explorer; (c) deleting in safe mode; (d)asking virus scanners to delete them when identified as 'web search' related etc. Every approach is met with messages like "cannot delete, you do not have access" or "file is in use" etc. Any suggestions?
