Webroot Antivirus w. Spy-sweeper is an ok protection suite but is really more of a Commercial or corporate product. You may want to consider other options such as McAfee, Symantec
(aka Norton), Kaspersky, or BitDefender as they are more consumer gauged products with a better user-interface and some with even better detection rates the Webroot, but if you have already purchased Webroot just stay with it until your subscription expires as it will provide adequate protection from anything that may harm your PC.
Hope this helps, also I have included links to the consumer programs i listed above.
