The June update for the MSRT tool is aimed at Trojan created to steal passwords, especially those Trojans used to get hold of passwords used for online gaming.
Microsoft’s main enemy for this update was Taterf, a Trojan targeted at World of Warcraft and Lineage players. According to Microsoft’s data, the MSRT tool wiped the Taterf malware from over 700,000 machines on the first day. The numbers grew to a staggering 1.27 million in less than two weeks.
Another victim on the MSRT list was Frethog, which has been evicted from 200,000 machines on during the first day.
In the beginning, the MSRT tool was aimed at worm infections such as Nimda. However, its protection area expanded over time.
