Most Significant Bits-CD (www.msbcd.com) has Norton SystemWorks 2001 Professional Edition (Full Retail Box Version)for only $6.95 after $30.00 Ugrade Rebate (expires 12/31/2001). It won't work with Windows XP, but $6.95 is a very small price to pay for the anti-virus protection alone. Here's the link:
Since shipping is only $4.95 PER ORDER, you might want to add a few stocking stuffers for the kids... or for mommy and daddy too! I've had good luck with this company.
