I use >Zone Labs< Zone Alarm Pro firewall security suite with anti-virus and spyware detection & removal utilities. It costs about $50 a year to subscribe to the upgrade service, but I've never had a virus trash my system, or been bogged down by spyware since I started using it. And these days, an unprotected 'puter gets probed by bad guys within minutes of logging on to the 'net. With a good security suite, you can amuse yourself by looking at the logfile listing all the times that malware tried to infect your system, while you surfed by, unharmed.
