For the first reason: I don't know if you have this experience when you use a WindowsXP system. In the Windows Explorer, click Right-click on the selected file to suddenly slow down.
Soon some questions have been raised soon, and open the resource monitor found that the CPU usage rate is 100% when clicking right click.
Is this a bug of XP? Recently, Microsoft finally released a report in the resource manager in Windows XP, selected in the Windows XP resource manager, and the list will take up a lot of memory!
Microsoft said in the text that when you in the resource manager of Windows XP, after the file is selected, the CPU usage is 100% in the display pop-up menu.
This means that any file copy operation "may stop the reaction" (hereinafter referred to as). The network connection speed will also decline significantly. At this time, any flow operation, such as listening to music, may be interrupted!
But to solve this problem is also easy, you can turn off the "Transition Effects" option in the menu bar and the toolbar, or point the left button before the right button.
This lack is exemplified in all Windows XP versions, including fixing the SP1, and SP1A version of the BUG. The second reason: It is basically considered to be a problem caused by NAV. The temporary effective way is to adjust the system time to January 7 or before, waiting for a clear explanation and solution. If you can't endure, please uninstall NAV (to ensure that the uninstallation is smooth, you can first adjust the system time). But still do not recommend that domestic kills, it is recommended to install KAV. In addition, according to the Virus version of the report, NAV2004 and NAV CE do not have this issue. (1) It is possible that the software settings need a confirmation of subscribering updates on this day. Please try LiveUpdate your NAV at the system time. Even if there is no prompt to have any new updates. You may need to try a few times. If you can't, you can consider reloading Na2003 and updating. Refer to the layout article. (2) Operating virus library 20040107-004-x86.exe (not i32 version) may solve the problem. If your problem has been resolved, please express your solution in virus, thank you! Some current situations (but still unsequently): (1) related to NAV, but NAV CE, NAV 2004 is not affected. (2) Most of them are the latest virus library (0107), but there are exceptions (3) Most of them are NAV 2003 (4) is the WIN 2000 / XP system, but there are also similar reports from Win 98 systems. (5) Most of them are pirated NAVs. The third: According to the Global Anti-Virus Monitoring Network, there are two viruses today, they are: "Win32.porex.b" and "Backdoor.Bay" viruses. "Predis" is a systemovirus, which can infect all EXE files, produce a large amount of junk documents, kill a variety of anti-drug processes, and send mail out of the virus after starting. "Laurel" is a latter program that is injected into the system process. If the user clicks the right button pops up the shortcut menu, the virus will be activated, so that the system slows down.
Hot virus this day:

Anti-virus expert advice: establish a good safety habit, do not open suspicious emails and suspicious websites; close or delete services unwanted in the system; many viruses use vulnerability to spread, must make patch to the system in time; install professional anti-virus software for real time Surveillance, usually to open the real-time monitoring of antivirus software when online.
