There are a lot of antivirus in the market and the trend today is for Internet Security Suites which offers anti-spyware, firewall, antivirus, all in one. However, the price for internet security suites are quite high so some users just purchase antivirus software and then rely on Windows own firewall.

What's great about the K7 Antivirus is that even though it's not an Internet Security Suite, it offers Anti-Spyware and email scanning as well. When you purchase the K7 Antivrus software, you get a license for up to 3 PCs for only $26.96.

The K7 antivirus features frequent updates, real-time scanning, enhanced scan engines, and a very fast antivirus scanner. It's also very light on your system resources and doesn't require a lot of high system requirements so this would be a good antivirus if you still have an aging PC with Windows 98 and Windows ME.
