Once my machine has booted up I get the outlook express compact files pop up message. I do not and have never used outlook express for email, so why does OE issue this message. I have tried to remove OE completely from my machine, but all attempts to delete or rename files result in either a "file in use" message, or in the case of a rename attempt, the system creates a new copy. Full AV scans of the machine do not identify any trojan or malware problems and all security patches are applied. Can anyone advise how to stop this message occurring please?Chrs Bert2 people got this answerI do too
