to eliminate the possibility of poisoning, you can take the following measures first:

Method 1.

1. Repair with a command: If you find that your IE is out of order in Windows XP Service Pack 2, try to "run" this command: "%programfiles% \ Internet Explorer \ Iexplore.exe"/rereg "(double quotation marks are indispensable), which can help you re-register all components of IE and completely repair the paralyzed IE, but it is not suitable for other versions of Windows.

2. Download and install 361 Security Guard-Advanced-Repair IE-- Check the options to be repaired or select all-Repair immediately. After the repair, reset IE home page.

3. start IE browser-tools --Internet options-advanced --HTTP1.1-- add a check mark before "use HTTP1.1" and remove the check mark of "use HTTP1.1 through proxy connection"-ok.

4. under the common options of 361 security guards, click "kill popular trojans" and "clean up bad comment plug-ins" respectively-start scanning-check the scanned popular trojans and bad comment plug-ins respectively-click "kill immediately" and "clear immediately" respectively. Pay special attention to malicious rogue plug-ins such as 3721, Yahoo Assistant, Chinese Internet Access, Baidu Search, etc., which should be resolutely eliminated.

Method 2.

The following methods can have obvious effects:

1. There are too many system startup items, which affect the startup speed. Methods: Start-Run-Enter msconfig-Start-In the startup items, you only need to keep ctfmon (Input Method) and anti-virus software, and the others will be ticked off-

2. Turn off the special effects in the system properties, which is a simple and effective way to speed up. Right-click my computer-Properties-Advanced-Performance-Settings-In the visual effect, set it to adjust to the best performance-OK.

3. Right-click Desktop-Properties-Desktop-Background-Select None; Color—Select black; Desktop background has the greatest influence on boot speed; It should be removed.

4. screen saver—select none. Cancel system standby and hibernation, because system standby or hibernation takes up all physical memory.

5. Appearance-Windows and buttons-Select Classic Style-Color Scheme-Select Windows Classic.

6. Keep about ten at most; Some icons that are not commonly used should be deleted from the desktop.

7. For some things that are not commonly used and you don't want to delete, you can put them in a folder. Method: Right-click the desktop-arrange icons-run the desktop cleaning wizard, and you just need to clean up according to the prompts.

8. If your system antivirus software starts at random when it is turned on, the antivirus software will scan to check whether the icon link is toxic. It will take a certain time, and the icon will be displayed slowly. This is normal, and it is not a problem with the computer. There are many online in this respect, so you can search.

9. Start-Run-Enter regedit and press enter. Open the registry editor, find HKEY _ local _ machine \ system \ currentcontrolset \ control \ sessionmanager \ memory management \ prefetch parameters, find the EnablePrefetcher primary key on the right, and change its default value from 3 to 1, so that the scrolling time of the scroll bar will be reduced.

11. Right-click "My Computer"-Properties-Hardware-Device Manager-click the "IDE ATA/ATAPI" option-double-click "Secondary IDE Channel"-Advanced Settings-Device Type, and change "Auto-detection" to "None", mainly making the same settings for the IDE channel, so that the scroll bar of your computer will run three times at most, and the startup speed will be increased.

11. enter gpedit.msc in "start → run" to open the group policy editor. Find "Computer Configuration → Management Template → Network →QoS Packet Scheduler", select "Restrict Reserved Bandwidth" on the right, select "Properties" to open the dialog box of Restrict Reserved Bandwidth Properties, and select "Disable". This releases the reserved bandwidth.

12. It is recommended to cclean frequently (such as system junk files and system registry junk) and recommend you a small program in cclean (see the final attachment).

13. It is recommended to set IE temporary files and virtual memory in your computer on a non-system disk.

14. In normal times, don't open too many application software at the same time, and turn off the monitoring function of anti-virus software or other optimized software, because the monitoring function of anti-virus software or other optimized software particularly occupies system resources.

15. Restart the computer. After booting to the desktop, a window will pop up. Add a check in the small box and click OK (because the system configuration utility has been changed).

In addition, you should pay attention to cclean frequently and defragment the disk on time. There are quite a few online in this respect, so you should pay more attention to search yourself.

Finally, I suggest that you download and install the Windows Optimizer to clean and optimize your system comprehensively. After cleaning and optimizing this software, the running speed and performance of your system will definitely be significantly improved.
