Zurdo' Thanks for your reply, and the link. I will register on that forum. Have since tried many times to perform a local scan on my C drive and even when Task Master shows nothing but e-trust is running, every file shows "Status" :- Open Error. This , I gather from the help files, means that the files are open and e-trust is unable to gain access! If that is so, why does a scan take over 30 minutes??
