But Microsoft's own data doesn't always support William's contention that piracy, and the hesitancy to use Windows Update, leads to more infected PCs. China, for example, boasted a malware infection rate -- as defined by the number of computers cleaned for each 1,000 executions of the MSRT -- of just 6.7 per thousand, significantly below the global average of 8.7 or the US's rate of 8.2. France's infection rate of 7.9 in the first half of 2009 was also below the worldwide average.
Wait a minute. We are using the MSRT stats to debunk the idea that piracy and not running Windows Updates results in more malware. MRST is usually run as a part of Windows Update...so the people not running WU don't run the tool and aren't even a part of the stats. Whether Microsoft is right or wrong, this argument is flawed.
