What is security? 80% viruses can intrude into Windows 7

According to foreign media reports, Sophos, a well-known Internet security vendor in the UK, recently said that Windows 7 User Account Control (hereinafter referred to as "UAC") security features can only defend against 20% of the virus.

No anti-virus software is installed. Under the default system settings of Windows 7, Sophos tests UAC with 10 new viruses. The results only prevent two viruses.

UAC is designed to prevent unauthorized software from running, and most of the current viruses can bypass this level. This indicates that the security of Windows 7 is not significantly improved compared with previous versions. Users still need to install anti-virus software after purchasing a new PC.

Of course, Microsoft also recommends that you install anti-virus software and provide free anti-virus software Microsoft Security essen.
