Starting with Windows XP, Microsoft began to develop and release the corresponding 64-bit version for each Windows operating system, but because of the compatibility issues between the current 32-bit applications and 64-bit operating systems, 64-bit The operating system is far from universal.
However, many friends who like early adopters started to switch to 64-bit operating systems early.
Among these early-stage 64-bit friends, a large number of people are letting their operating systems "streaking" (usually, everyone will not install any anti-virus software operating system) The state is called "streaking" state, and the 64-bit operating system is considered to be sufficiently secure to be infected and destroyed by viruses. So, can such behavior really guarantee the security of the system? When we changed the 64 operating system, we really didn't have to install anti-virus software anymore.
The virus and malware were developed to achieve some purposes, such as destroying the computer's system and data, stealing information from the computer, etc. In order to achieve these goals, the virus or malware itself needs to be infected. Most mainstream operating systems and software do. Therefore, virus or malware writers usually choose the most popular and mainstream 32-bit Windows operating system as the target of infection and attack. This is why the so-called "Apple OSX system and Linux systems are more secure than Windows systems", in fact, because their usage rate is relatively low, no value for attacks. In fact, OSX and Linux systems have even more security vulnerabilities than Windows. If their market share exceeds Windows, the virus programs for them will definitely be more rampant.
And because most of the viruses for 32-bit operating systems can't infect 64-bit Windows operating systems, 64-bit Windows systems now seem to be much more secure than 32-bit Windows. But as 64-bit systems and applications become more popular, viruses for 64-bit operating systems will certainly emerge. Moreover, with the deepening of the network in everyone's work and life, the destruction of Trojans and malicious programs is more serious than viruses, and these Trojans and malicious programs are completely capable of infecting 64-bit operating systems.
So, no matter which operating system you use, it is very necessary to install anti-virus software with active defense and network firewall. Don't wait until your important data is destroyed or stolen by viruses. Reinforce the dead!

64-bit anti-virus software is an anti-virus software type that is different from 32-bit systems for 64-bit systems. The basic functions of 64-bit anti-virus software and 32-bit anti-virus software are similar (the same version of the same anti-virus software has the same protection performance on 32-bit and 64-bit systems). At present, mainstream anti-virus software at home and abroad basically supports versions supporting 64-bit systems.
The security of 64-bit systems is higher. Therefore, some of the features included in 32-bit anti-virus software have been removed in 64-bit anti-virus software. For example, the small red umbrella anti-virus software under Win 7 64-bit system There is no self-protection function, mainly because the 64-bit system itself has good protection performance in this respect.
With the popularity of 64-bit Win7, there are more and more people who need to choose Win 7 64-bit anti-virus software. Here we recommend several 64-bit anti-virus software that is more suitable for the public and works well:
Microsoft Antivirus software MSE (download), avast (download), Norton (download), McAfee (download), Kaspersky (download) and NOD32 (download), Rising (download), among them, Microsoft anti-virus software MSE (must pass genuine verification ) and the avast home version can be used for free forever.
