Do yourself a favor. #1= Install a firewall, you can get ZoneAlarm for free and it works great. I get about 50 to 100 attempts to get into my system in a 2hr. session of poker. #2= Subscribe to a virus protection like McAfee which updates automatically. Cost you $19.95 when they run a special.They have been great for me. #3= Enjoy yourself and stop worrying.
