One of the important components of a HIPAA compliant office is having up to date Anti-Virus software on all of your PCs. This week, newegg.com has the 3=license McAfee Antivirus software on sale for $40 and McAfee has a $40 rebate, making this essentially free. Shipping is free, but I believe you still have to pay for the postage stamp for the rebate.
I have no connection to NewEgg other than ordering a boatload of equipment from them over the years.

I personally use McAfee for my AntiVirus.
