Experience three network security online detection service _ Surfing

Computer popularization, broadband prevalence, now many friends online time is very long, so the security of the system has become "the most important." Fortunately, many security sites now provide online detection services, can be a good help us to detect the existence of their own computer vulnerabilities and security risks, so that timely and effective solutions to these problems.

　　 first, the Internet Assistant Computer physical examination

In November last year, internet assistants launched a large network of public health activities, "the National Physical Examination Week", the arrival of the Spring Festival in 2005 again launched a free computer checkup activities (January 18, 2005 26th, although the activity has expired, but the official website still provides free download and online medical services).

Four, summary

Although we installed anti-virus software, anti-black software, and opened the network firewall, but because of viruses, trojans updates and variants of the speed, the ability to spread across the network is also strong, Some system vulnerabilities and open ports will not only become the targets of hackers, but also facilitate the spread of viruses, trojans and proliferation. Therefore, in addition to the timely updating of the virus library, Trojan feature library and open firewall, regular computer for a comprehensive physical examination is also very necessary, it can help you in time to analyze and find a computer in the leakage and security risks, user-friendly timely discovery, the right remedy to timely resolution, therefore, only the computer for regular physical examination, To prevent and resist the latest threats, to maximize the security and stability of the system.
