Internet service provider AOL has begun touting a free suite of antivirus software for its users. The offering, dubbed Active Virus Shield, is powered by Kaspersky Labs and automatically updates every hour.

The security suite offers a combination of traditional signature-based detection with in-depth scanning to protect against known and new viruses, as well as real-time file protection that scans individual files and email protection that monitors both incoming and outgoing email.

"The consumer PC security experience is long overdue for re-invention. With so many consumers online with inadequate security safeguards, it is time to make things like virus protection a fundamental right, not a risk," said John McKinley, president of AOL Digital Services.

Active Virus Shield can be downloaded at www.activevirusshield.com. Once installed, it regularly notifies users of their current protection status and provides recommendations to handle security threats.

"In today's environment of organised cybercrime and ever-changing online threats, it's more important than ever for consumers to have comprehensive virus and spyware protection that's continuously updated and easy to use," said Steve Orenberg, president of Kaspersky Labs.

AOL will also allow IE users to install a free security toolbar when they download Active Virus Shield. The toolbar will include a real-time update on their computer's security status via Active Security Monitor, a password manager, pop-up blocker, and a link to the Whois domain registration database to find more information on potentially suspicious sites.
