I have a buddy that does business over the internet. He saves everthing important to disks and only keeps the operating system on the computer.
He has all the spyware stuff but just re-formats the hard drive and re-installs the OS if he gets a problem he can't deal with.
Think I am going to do this as well and keep another computer for games and stuff and never put it on the net.
Makes some sense.
That's a ridiculous amount of work.
Keep your antivirus software ON and UPDATED at all times. Keep your firewall on at all times. Don't use Napster, Kazaa, BearShare, or other file-sharing programs. Run AdAware and SpyBot religiously.
Believe me, doing all that takes me maybe five minutes a day. Sifting through CDs to find a file wouldn't be worth the hassle.
