Microsoft removed 281 491 Zeus Trojans in five days
Microsoft reports in a corporate blog that since the Malicious Software Removal Tool (MSRT) has been updated, it has deleted 281,491 copies of the Zeus Trojan from 274,873 infected Windows systems. Thus, the largest botnet on the Internet has lost some of its zombies.
Zeus / Zbot signature support was added to the free MSRT program last Tuesday, October 12th. Statistics is given as of Sunday, that is, it took five days to clean up a quarter of a million computers.
In this statistic, several things are striking. First, the scale of infection. The experts' assumptions that the number of Zeus family botnets has already grown to several million computers were indeed fair. Surely only a small part of the bots have been neutralized. As of Sunday, the latest version of MSRT has checked approximately 86 million computers, while the total number of Windows-connected Internet computers is over 1 billion .
Secondly, why is Microsoft just now updating the program? After all, Zeus has long been in first place in the list of the most malicious network software, and was first seen back in 2007. It has always been said that this trojan is difficult to detect - but Microsoft itself has proven that it is real.

The director of the Microsoft Malware Protection Center added that since Tuesday Zeus accounts for about 20.4% of all the malware found by MSRT.
The Malicious Software Removal Tool for malware search and removal comes with the standard Windows Update update or can be downloaded separately .
