About a month ago I decided to give Microsoft’s new anti-virus product a try. Windows Live One Care offers anti-virus, firewall, and spyware protection in one product. The product is easy to install and was very intuitive in it’s use.
I have a Pentium M powered laptop that has 256MB of ram. Not a power machine, but for what I use it for it works fine. One Care says that it requires 256MB or ram to operate.
Once One Care was installed, it was easy to use and I saw no performance changes except when the tuneup utility ran. That was OK though as it was easily cancelled or scheduled for a low usage time..
About a month into using One Care, I started noticing the laptop slow down. It go to the point that the computer was practically unusable even for basic applications like Word and IE.
I was considering doing an entire re-install, but last night decided to disable One Care to see if it was causing this problem. Once the One Care services were disabled, the machine immediatlely returned to it’s previous level of performance.
I would not recommend One Care for a computer running at 256MB or ram and do not really believe that the performance would be good at 512MB, but cannot confirm this.
