Webroot to Offer Antivirus

At the end of this article defending the need for Spysweeper even after Vista is released Webroot CEO David Moll says that Webroot will soon offer antivirus in addition to antispyware. Its not clear if they are going to bundle with a competitor, if they are developing from scratch, or if they are going to buy someone.
Other interesting notes:
-Webroot has a half million dollar “usability” center where they observe normal people using the product.
– They take time to play offense against their product, trying to be the bad guy and look for ways to circumvent the product, so they can close those holes.
– If you get a patent while working for the company you only get a 2k bonus.
