I want my CPU to be fully proected from viruses, spyware etc..etc..

Whats my best bet?

Can I run multiple programs at the same time?

If yes, which spyware and anti-viruses and firewalls work together very well?

I am looking for a career working with computers and that would help me get a telecommuting position and also make more money than I am currently as a teacher, but i know I may have to return to school. Which career is the best bet in IT? Here are the choices: Information Systems Security, Data Communication Systems Technology, Software Engineering Technology, IT Computer Network Systems, IT - Software Applications & Programming, IT - Web Development. If there is something not on this list you’d like to suggest, feel free to add it and describe it. Thanks for your serious and helpful replies.
no website links please!

I run a laptop with a direct B/band connection to the net. l use Win XP Home pk2 I run free Z/Alarm, free Windows care V2, free Spybot S/D and free adaware. l figure it’e better to buy one all rounder. Z/A seems the best bet. Any thoughts

what kind of information can you find on the social security death index?…I'm doing some family research and I was able to find my gg-grandfather's ssdi, it has his birthday (dec. 25, 1860) and death-date (jun. 18, 1965) and where he died (Tulare, California), but nothing about the parents…other family member's index's have had something about parents on them, even if it's the father's surname or mother's maiden…I also am having trouble finding a death certificate. Where would I look for that, and would his parent's info for sure be on that?

I've been using Ancestry, Family Search Org, Roots web, and Family History Records data bases.
will it be my best bet to order the actual death certificate for his parent's information?
