Total Internet Protection (from Spware, Viruses, Identity Theft)

1) Norton 360

Reasons why I like them:

• Robust (This software does it's job - protection from spyware, viruses and Identity Theft, well)
• Unobtrusive (you can install software and forget about it)
• Daily, automatic updates
• Reliable
• Cutting edge - can clean the most current viruses and harmful spyware in the background without it prompting you every minute, to tell you that it's doing it. 
• Easily integrates with Windows Operating Systems
• Their people are experts in the field.
• Caveat: takes up a lot of space on hard drive. Ensure that your computer meets requirements for installation...or else it will slow down your computer.

2) Get McAfee Total Protection for only $39.99 after 50% off. Regularly $79.99.
