McAfee has also tweaked other performance aspects, such as administrators' ability to collect data on the status of their deployed machines through an improved management console, Viveros said.

McAfee has also thrown SiteAdvisor into the package. SiteAdvisor scans Web pages that are returned after a query on a search engine and gives a yellow or red warning for those that may harm a person's PC.

A new feature in 5.0 allows administrators access to those sites and only lets users go to those that get the green check icon. Previously, users could still visit sites that were marked as harmful or questionable, Viveros said.

Total Protection Service 5.0 supports the following languages: Portuguese, Brazilian Portuguese, Russian, simplified and traditional Chinese, Dutch, German, Spanish, English, French, Italian, Japanese, Korean, Danish, Swedish, Norwegian, Finnish and Hebrew.

It costs US$40.30 per user per year up for up to 50 users, $32.75 for up to 500 users and $29 for up to 1,000 users, McAfee said.
