Hi, I installed Windows XP SP 2 RC1 today. The first thing that met we when I rebooted after the install was a huge security window which told me I that Windows firewall was enabled since no other firewall was detected on the system. It also told me it would continue to bug me if I disabled the built in firewall or didn't install a firewall recognized by Windows. Do I have to add that LnS was running like a charm in the background? The same was the case with AntiVirus. I was told that I didn't have anti virus installed and asked if I wanted to be taken to where I could purchase some. I do have Solo AntiVirus installed. Of course you will be taken to Symantec and a couple of the other biggies in this area unless you disable this stuff. When it comes to firewalls I'm afraid the same thing is the case: You need to have one of the best known firewalls installed, ones that have an agreement with M$ or XP will keep warning you and enable it's own firewall. After some poking around I found how to disable this stuff, but I was warned all along the way how I was putting myself in danger. If a great product like Look n Stop shall stand a chance after people do the SP2 thing XP needs to be able to detect Look n Stop (and a broader base of firewalls) or a lot of people will be pushed towards the built in firewall or some major brand osince it's simply too much hassle using anything else. I uninstalled SP 2 again. It looks like the major push in SP 2 is shouting: "WE ARE MICROSOFT AND VERY CONCERNED ABOUT YOUR SECURITY (so we will put some new fancy shield shaped icons in your systray, start some new auto update services and push selected products on you wheter you want it or not)." Oh well, there may be good security improvements in SP 2 under the hood, but again M$ is doing what they are best at: Marketing.
