Open txt file in Win7 shows "Cannot find script file" solution

First of all, let's analyze the cause of the fault. Under normal circumstances, after we double-click to open the txt file, the win7 Ultimate computer pops up the "Unable to find the script file" prompt, which may be caused by computer poisoning. However, after our anti-virus, the txt file could not be opened. The specific solution is as follows:
1. That is to say, after our anti-virus, although the software is displayed in the Win Ultimate version of the icon of the Notepad, but when it is specifically opened, the program is not in the form of Notepad. Open, we only need to change the way the program is opened.
2. First, let's find the txt file in win7 Ultimate, then right click and select the default open mode. After that, we can select Notepad in the open mode.
