Kaspersky :
Overview
Kaspersky Labs has been one of the best antivirus software developers in the world for over a decade and now Kaspersky Anti-Virus 2009 only strengthens that reputation. Founded by Natalia and Eugene Kaspersky in 1997, this Russian company is often the first to find and identify new viruses. Long used in Russia and Europe, Kaspersky is now making inroads in the North American market. Kaspersky Anti-Virus 2009 is one of the most effective antivirus packages in the world today and boasts a great interface with easy to use and intuitive controls.
Like so many of the other antivirus packages including BitDefender, Kaspersky Anti-Virus comes with an antispyware component. Kaspersky's software is among the best products in the world, but at $39.95 for a one-user for one-year license, it’s on the high-end of the software we reviewed. There are no complaints about Kaspersky's effectiveness or ease -of-use. As a result, Kaspersky Anti-Virus is the “TopTenREVIEWS Silver Award” winner. If you're looking for antivirus protection for small business, you might be interested in Kapersky Anti-Virus for File Server or Kaspersky Business Space Security, one of the best small business antivirus software suites available.

Webroot:
Webroot Antivirus with Antispyware and Firewall is a solid product from Webroot Software.

Both programs have been awarded all major industry awards and certifications and can dynamically alter themselves to fight emerging threats that hit the World Wide Web every second of the day.
The internet provides unlimited opportunities for communication, education, commerce and entertainment; however, it also provides opportunity to malevolent programmers and pranksters to distribute their viruses, spyware, worms, keyloggers and more.
