It is good practice to keep a single good antivirus or antispyware, so the system works with good performance.

You can choose among either.

Good luck
the antiv virus free download thing you got with google is just a virus scanner not a remover. i think i would recommend getting avg for free products but in my opinon you should get this:

Norton. it can be used on three computers.

these are the feature's:

full backup of WHOLE hard drive

registry cleaner

live virus and spy-ware update

virus and spy ware scanner

firewall

identity theft protection(for shopping and untrusted websites)

pop up blocker

add on blocker

optimize disk

FREE on line support that's like msn (talk live to agent to help with problems

say you buy all in one security version 1 you can update to version 2 for free
