I have "Defender Beta" running on my PC, as to is reliabillity it's hard to say as I also have other products installed. I've run scans with it and it has removed some items, however when I run spybot it finds others. The only thing I can think is it's either "not very good or it only checks some areas" which in itself is not good. So far i'm not all that impressed, but it's early days.
I use Mozilla Firefox for all internet use where possible, which I find more stable than Internet Explorer, once it's installed and the add-ons have installed themselves it's quicker then IE, it also doesen't have the same security probs as IE. I tend not to trust new products from Microsoft, but am willing to give then a try, at the first sign of problems though, it's removed VERY quickly.
As it is a Microsoft product it may only scan items when using IE, if that is the case maybe I should remove it anyway. Does anyone know the answer to this.
