What is the cause of win xp failure? The firewall is also mischievous

Failures are inevitable. When we use a computer, the fault goes hand in hand, but many times we can solve it ourselves, but if we encounter some inexplicable faults, how to use it. When we use the system, sometimes there may be some unexplained failures. These faults may be caused by a firewall in Windows. Let's take a look at some of the faults caused by the firewall.

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 failure, such as pop-up "read error", "install *.exe error", etc., or simply crash, or install it. After that, it cannot be used normally. 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 is not responding after clicking the “OK” button. The most frightening thing is that even if the system restore is barely completed, some programs also Can not be used normally (such as Kingsoft Shadowmaster).

So things can't be seen on the surface, the firewall is also mischievous, it can protect the security of the system, but also can make the system malfunction, things always have two sides, we must be mentally prepared.
