Windows system can't open 4 solutions for .exe executable file

Today, a colleague has a serious problem with the computer. After opening my computer, a dialog box pops up saying "Cannot find C:\\WINDOWS\\system32\ undll32.exe”, then open some installed software programs but pop up one for you. The dialog box for selecting the open mode, the Rising anti-virus software is disabled, the whole machine is like a smash, and no program can be run. In fact, this is a virus or Trojan to modify the way the exe file is opened, resulting in the inability to open any executable file. After research, I finally found a solution.
