Thank you for your reply.
Frightened to death of procedures you suggest, not knowing anything about computers.
I have tried to recall backups from X drive.....Restore.. reduses to accept tham..At the moment I have found my ISP did not update my security programme (McAfee), maybe that is why problem occurred? I am downloading McAfee, if able to do so?????I shal give laptop a full scan and keep my fingers crossed.
Here's hoping & thanks........Darcy
