this could be a problem that may need a computer whizz to sort out as some trojans are absolute devils to get rid of.
the only real remedy is not to get them in the first place - never ever open an email and especially an attachment that has been sent from somebody you dont know and even if it HAS been sent from somebody you know ALWAYS scan any attachments for viruses using your firewall anti-virus zapper.
