Microsoft is claiming major success at cleaning the notorious Zeus crimeware trojan from infected Windows machines.

One week after adding detections into its malicious software removal tool, Microsoft said it nuked Zeus (also called Zbot) 281,491 times from 274,873 computers.

According to Redmond's Jeff Williams:

Of the 1,344,669 computers cleaned, this is about 1 in 5, a ratio that’s higher than we typically see even when accounting for the normal, first-month spike which results from adding a new family but not exceptionally so.

To put this in greater perspective the removals of Zbot are almost as many as the removals of the #2 and #3 malware families this month combined (Win32/Vundo and Win32/Bubnix respectively). Approximately 86 million computers have run this version of MSRT as we compile this data so we should expect this number to increase as the month continues.

The malicious software removal tool, which is updated and released on the second Tuesday of each month, scans checks computers running Windows 7, Windows Vista, Windows XP, Windows 2000, and Windows Server 2003 for infections by specific, prevalent malicious software.
