Well McAfee got a lot of annoying messages and Norton slows down the PC. Nothing is perfect, but i prefer to use a firewall 'Zone Alarm' which is the best so far. Other 'Zone Labs' products are not that good such as the Antivirus and Internet Security, but the Firewall is the best so far. I don't use any of them and if i have to use one then it is Bitdefender. Can by a problem in getting the users list from the 'My SQL' or whatever databse is there. I don't think that the website is using the 'Sessions' to get the list of the online users .

Best Regards
