Nice!
Microsoft has launched "Fix It" software that keeps an eye on a PC and automatically repairs common faults.

The software basically adds the automatic diagnostics system in Windows 7 to older versions of Microsoft's operating system.

Once installed, the software gets updates about known issues with Windows or any connected devices, and regularly checks to see if a host machine has fallen victim. Once fixes become available it will tell users they are ready or attempt to apply them.
Let's hope this takes off and becomes more effective over time. There's really no reason why Microsoft shouldn't proactively fix common problems on people's machines, including malicious software removal. It is a major opportunity for Microsoft to make Windows friendlier to users who don't know much about software, and invariably end up with machines bogged down by malware and other problems.
