Tech,
What's the difference between Arovax and MS-AntiSpyware?
Does it do anything that Ms-AntiSpyware doesn't already do?
I think MS is better right now: features, number of detections.
Arovax is being alpha tested, without features yet.
You'll find a very fast scanning (even the deeper one), yet without resident scanner. Free.
It's an alternative to be tunned on... in the future, who knows
