The firm's Security Intelligence Report uses data captured by Microsoft Windows Defender and the Microsoft Malicious Software Removal Tool (MSRT) over the last six months.
The disclosure of new vulnerabilities dropped by 15 percent in the last six months of 2007, while the amount of malware removed from computers by the MSRT was 40 percent higher. Instances of trojan malware rocketed by 300 percent.
The number of potentially unwanted applications – such as spyware and adware – jumped by 67 percent to 129.5 million pieces.
"The criminals are clearly focusing on getting Trojans to download on PCs – it's the lynchpin to starting the process of gaining access," explained Vinny Gullotto, general manager of Microsoft's Malware Response Centre. "The sheer volume of threats we're seeing globally coming into the labs is staggering."
The report also claimed that newer Microsoft products are at less risk from these threats: MSRT proportionally cleaned malware from 60 percent less Windows
Vista-based computers compared to computers running Windows XP Service Pack 2.
