I have gone into all programs, accessories, system tools, backup I have selected the backup wizard advanced option and clicked next.

Which of the 3 options should I select if I am backing up in preparation for a clean install?

Backup everything on this computer,
Backup selected files drives or network data and
Only backup the system state data

Which of those 3 options should I select in preparation for a clean install of windows XP
My pictures, music and videos are my main concern.

I am a novice Linux server admin (I can us SSH, vi, cron, and understand config files), but I am willing to learn. However, I do not have hundreds of hours to research and learn all the ins-and-outs of Linux. I need something fairly turnkey:

What is the best server software that will do all or most of the following:
- POP3 server
- SMTP server
- Webmail server (with good standard features, like WYSIWYG editor, attachments, etc.)
- Web-based end-user configuration tools
- Anti-virus
- Anti-spam (blacklists and whitelists & RBL support required, spam filtering logic a plus)
- Authentication data stored in a database for easy management.
- POP-before-SMTP authentication

Similarly, I need to pick the best Linux OS to run this puppy on. I would like an OS with a wizard install, and one with adequate security for a publicly accessible server.

Last of all, it would be great if all of the above would be freely available for commercial use.

Thanks for your help!

I am trying to backup my data in Windows XP to a CD-R, but the backup wizard keeps telling me that, “I need to ensure it is a valid path, and that I have sufficient access.” What am I doing wrong??

My desktop appear a notice message “Your computer is in danger! Windows Security Center has detected spyware/adware infection! It's strongly recommended to use special antispyware tool to prevent data loss” in the black background.I can’t change the background anymore. I try to use NoAdware but nothing change. Sometime, suddenly a wizard auto appear to invite me see some scan adware tools but I always Cancel b/c I think it’s a trap, surely, I was trapped when I agreed to use the introduced scan tool before. How can I do to fix my computer? Please help me.
