Experts answer: 1, infected with the virus are often caused by this situationPerformance when you open IE, the IE interface, the lower left box Tip: being open page, but Lao Bantian no response. In view in Task Manager process (into the method, the mouse on the taskbar, right-click - Task Manager - processes) to see how the CPU occupancy rate, if it is 100%, canSure, is a virus, then you want to run other programs is simply suffer. This is what we should look up the process of greedily taking up CPU resources. Once found, it is best to record the name, then click the end, if not end, will have to boot into safe mode to remove the stuff, but also access the RegistryTable, (method: Start - Run, type regedit) in the registry dialog box, the point edit - find, enter the name of the program, found, right click delete, and then the search several times, often to completely remove Clean. There are many viruses, antivirus software can do nothing, the onlyWay is to manually delete. Second, set the proxy server with the some of the cheese, for some considerations, in the browser to set a proxy server (Control Panel ** Internet Options - Connections - LAN Settings - Use a proxy server for the LAN), set up a proxy server is does not affect QQ network, because the QQ with the 4000 port, and access to the Internet using port 80 or 8080. This is a lot of cheese they can not understand why the QQ, while the reason can not open page. The proxy server is generally not very stable and sometimes can, and sometimes can not go. IfThis setting, please cancel the agent on it. 3, DNS server error explain the so-called DNS, or domain name server (DomainNameServer), which convert the domain name to identify the IP address of the computer, such as the Shenzhen Window (www.sz.net.cn)Corresponding IP address is 219.133.46.54, Shenzhen Hotline (www.szonline.net) corresponding IP address is 202.96.154.6. If the DNS server error, then the domain can not be explained naturally can not get online. If this is the situationSituation, sometimes the network service provider or ISP issue of access can call the Advisory ISP; sometimes the router or network card problem, not with the ISP's DNS service to connect. This is the case, can the router off for a while again, or reset the router. Or the card can automatically searchTo the DNS server addresses, you can try to use the specified DNS server address. The properties of the network where to, (Control Panel - Network and dialup connection - local connections - right property-TCP * IP protocol - Properties - Use the following DNS server address). Different ISP have different DNS address, such as telecommunications common is 202.96.134.133 (main use) 202.96.128.68 (standby). Updated network card drivers or replace the card would be a thought. Fourth, the system file is missing cause IE not start this phenomenon is quite common, as: 1, system instability manifested as frequent crashes, often getting reset, illegal shutdown causes the system file is missing; 2, software and hardware conflicts Changbiaoxianwei caused some programs installed network card driver conflict or conflict with IE. Since the introduction of Hyper-Threading CPU INTEL after, there is a prominent problem is that XPSP1 IE6 under the conflict with Hyper-Threading; 3 Viruses cause the system file is corrupted or missing. If this is the first case, try repairing the system, 2K or XP system, put the original installation CD-ROM (Note: must be the original installation CD), at the beginning - running in input sfc * scanow, press Enter. 98 The system can also check with the sfc command. If is the second case, can be hardware or recently installed programs to uninstall, 2K, XP's system can be machine startup Hou, Chang An F8, into the Start menu, select "Last Known Good Configuration", if the XP systemSystem, you can also use the system restore function, the general would soon solve the problem. If it is XP system because of the reasons for hyper-threading CPU, Hyper-Threading disabled in BIOS, or upgrade to SP2. (Of course, XP SP2 to upgrade involves a lot of knowledge and pay attention to the problem, in this limited space
