How Windows 7 resists attacks from malicious programs

The Windows 7 operating system is a relatively secure operating system. Its "xp mode" is very secure when running Office 2003 (virtual machine) and Office 2007 (locally running), can destroy the operation of malware and interrupt many hacking tools. This benefit is a great experience for the user.

No computer system is completely secure. There are also insecure issues in even the most secure systems, such as security holes in operating system code. This means that Windows 7 is more secure than its predecessor Windows operating system.

You may not have heard that when a security vulnerability is exposed, Windows 7 is subject to serious scrutiny like the OS X operating system. Earlier, Microsoft discovered a security vulnerability in Windows Vista, Windows Server 2008, and Windows 7 RC. The security vulnerability in Windows SMB (Server Message Block) has not been exploited by hackers, but Microsoft warned that hackers who successfully exploited this vulnerability could take complete control of a user's computer. Most attempts to exploit this vulnerability will cause the affected computer to stop responding and restart.

Microsoft has released measures to bypass this vulnerability. Microsoft said the security vulnerability has been fixed in Windows 7 RTM and Windows Server 2008 R2. Some of Microsoft's best security features in Windows 7 are almost unintentional and have not been widely publicized.

PureWire's Paul Royal's latest report in SC magazine says Windows 7 is by far the most secure Windows operating system. He said that many attackers have difficulty finding attack routes, such as social engineering conspiracy.

The security of Windows 7 is mainly due to the fact that this operating system fixes the route of injecting malicious code into memory. In addition, Windows 7's "XP mode" may make attackers more headaches. The XP mode is implemented using hardware virtualization extensions. The commonly used hacking tool rootkits also rely on hardware virtualization and a special privilege level called VMX root mode. Since Windows 7 now uses hardware virtualization, attempts by hackers to exploit hardware virtualization have failed. Therefore, a common hacker rootkit tool "BluePill" does not work correctly in Windows 7. In addition, the XP mode of Windows 7 can also destroy the operation of many malware.
