It has been estimated that 90% of all machines connected to the Internet have been compromised by some form of malware. While there are various delivery methods for malware, e-mail is one of the most common.
Microsoft purchased GIANT and has used its anti-spyware software to create the Microsoft Windows Malicious Software Removal Tool, which can be downloaded and installed for no extra fee. You can also purchase a full-featured third-party tool like CounterSpy from Sunbelt Software for around $20 USD.
