Windows, being the most popular desktop based operating system, is also prone to attack from viruses, Trojans and other Malwares. Windows does come with basic protection against these and with Windows 8.1, Microsoft has included the Security Essentials. But with all these protection, the main problem you could face is that one virus attack could make your Windows unstable and this could lead to many privacy issues as your personal information could be at risk.
