Keep your firewall running, run an IDS, such as Bro, OSSEC, or Snort, and don't click on unknown links coming into your e-mail box.
Thanks shadowace- I do have the firewall, and stRicT no link or attachment policy for emails as others use the computer too, and they have learned not to click links u less they know the person and the ,ink is tO something expected like a youtube video or known shopping site or whatever.
I hadnt heard of the ids before, hnaks I will check those out.
