Analysis of WinXP system failure caused by firewall

Firewall is an important tool for our computer to protect itself. It can prevent the virus from invading it during the use of the computer. A firewall is very important. However, its improper use can also cause the computer to malfunction. Let's take a look at the firewalls that cause problems when they are used:

First, when installing the program

Many programs require the firewall to be turned off during installation (such as WPS Office 2003). Some programs are not directly stated, but if they are not closed in time, it may cause installation failures, such as pop-up "read error", "installation *.exe error" and other information, or simply crash, or can not be used after installation. . The author has been repeatedly verified when installing programs such as Kingsoft Studios and Office XP.

Second, when defragmenting

When defragmenting in Windows XP, the screen saver no longer interferes with defragmentation as it does in Windows 98 (every time you have to start over) ), but the virus firewall still plays a role in interference, especially the Kingsoft Internet Security firewall, which will make the defragmentation impossible. There will be repeated disk icons in the sorting list, and it will take a long time to pop up the prompt: Disk fragmentation cannot be sorted out. , certain error. At this time try to turn off the firewall and see if it is normal.

Tip: This is not the case when running the defragmenter at the command prompt.

Third, system restore

Windows XP system restore is almost a panacea, but you may encounter the following situation: when creating a new system restore point System prompt: Unable to complete the creation of a new restore point, restart your computer and run System Restore again. However, the creation of a new restore point cannot be completed even after a reboot. In fact, the culprit is still a virus firewall. As long as it is turned off, it can be restored.

The virus firewall also has an effect on the process of restoring the system to a certain time in the past. The system does not respond after clicking the "OK" button. The most frightening thing is that even if the system restore is barely completed, some programs cannot be normal. Use (such as Kingsoft Shadowmaster).

Be careful with the use of the firewall, otherwise the computer will not function properly.
