Machine poisoning, sweeping rundll32, serious consequences

Today, my machine is completely poisoned. Anti-Virus Software keeps prompting you that there is a virus in the.../Local Settings/Temp folder. Kill and kill (it seems that a rundll. dll related thing has been killed in the middle). At the end of the day, the machine encountered a major problem. Click All applications (or enter commands in Start> RUN). The open mode dialog box is displayed. Right-click the IE desktop icon and the prompt is"Application not foundC:/Windows/system32/rundll.exe ". I have been searching for the Internet for a long time. I have encountered many people with the same problem. There are all kinds of arguments, and it won't work after a long time. I was about to give up. I didn't find the system installation disk when I was preparing to reinstall or repair the system. Then I tried while searching and finally found a method for cracking. Here we will summarize that if we encounter similar problems, we will find them online again. Congratulations, you don't have to find a solution online. The specific operation is as follows:
1. Open C:/Windows/system32 to cmd.exe and double-click it;
2. Enter the character command line and enter assoc.exe = exefile
Then all the problems mentioned above are solved.
Of course, it is necessary to mention the previous experiment.
After entering the character command line,
/> Regsvr32 rundll32.exe
Tip: You have already completed rundll32.exe, but cannot find the dllregisterserver Input Point. Rundll32.exe does not seem to be a. dll or. ocx file
/> Regsvr32 rundll32.dll
Prompt: loadlibrary ("rundl32.dll) failed-the specified module cannot be found

If there are other sequelae, I will further summarize them here.
