I am trying to help a friend whose system is running linux/firefox which is a new experience for me. I have been lazy all my life and used windows based systems. (As an engineer in my discipline as well I have a strong aversion to using anything that is non standard and try to go for the most common. Second mouse gets the cheese so to speak).

She appears to have gained a virus that has acessed her hotmail account which is sending messages off to people on her address book directing them to spam sites. She has asked me to look at fixing it.

My first challenge is working my way around the system which is completely different and confusing to anything I have used. (where is file manager???? FGS) and I cannot seem to do any of the things I would normally do.

Can anyone help me or make some suggestion on how to fix it.
