ANTIVIRUS TYPES

Hello,

I have a problem with my system, the task manager was disabled by the administrator. I knew it was a virus and so I formated the system. However, I have several harddrives(Partitions) on the system. I have formatted the drives with the OS but have saved/untouched the drives with my data and stuff.

I want to reinstall my OS(windows 98 and XP) when I finally get a new cd drive and have this problem:

I have the following antivirus and want to know which one is better to use.
- Mcafee
- Panda
- Kepersky

Pls reply soon.

Also what cd brand should I buy, I bought LG but regret it.
My oldest system uses NEC but it still works.

I am planning to buy a DVD ReWritable
