Global Threat Trends - March 2010
There are an average of 3 different malware families per infected computer (both globally and in the US). This means that on average, when a computer is infected, we find three different malware families installed on it. However, this average seems to be slowly but steadily going down each month. This might indicate that malware operators are now tending to consolidate their operations and using single programs to perform multiple actions.
