Input Method -- can't the root cause of "Data Execution Protection" be disabled?

This computer has not been used for a long time.

For dual-System Windows XP SP2, I started it.
As a result, after entering the system for a few minutes, a box is displayed: "data protection ". At first, I thought it was an accidental error. I did not care about it after I closed it. However, the similar box is still popping up.

Bug? Virus? There are quite a few people who have encountered this problem. It seems that the newly added "Data Execution Protection" function in WINXP SP2 causes such problems. Based on the retrieved data, you can customize the "Data Execution Protection" processing behavior (four methods ):
Windows XP Service Pack 2, Windows XP Tablet PC Edition 2005, and Dep in Windows Server 2003
However, these methods do not seem to work for me? Whether it is set to "always enable" or "always disable", I still see this annoying box.

In desperation, I was prepared to reload the system, my ultimate method. Warm up first. If you don't want to install it all over again, first "upgrade and install" (that is, overwrite the installation ). Therefore, the installer runs directly on the current system instead of killing the system first. On the way to the installation, I found that the default "Ziguang PinYin Input Method" of the system was very difficult, and there was always a problem in switching the input method. I think it must be a disaster caused by the "Data Execution Protection. No way. You have to change the default input method ....... Then, it seems like a miracle, I switch between the several other input methods, and there is no fault. Will it all be caused by this "Ziguang PinYin Input Method? Haha, no matter how much it is, try to know, so this Ziguang pinyin was killed. However, this Ziguang was not sacrificed in vain. After it was removed, it never saw any annoying box. I set the "Data Execution Protection" option to "enable Dep only for basic Windows programs and services" (that is, the default configuration-"enable"), and these boxes are no longer available.

It seems that all these problems are caused by the problem of this input method. I don't know whether the root cause of this "input method problem" is itself or another person. I am not willing to pack this Ziguang pinyin for the moment, just use it.
