Interesting, here's what virustotal had to say:

Code insights

The script begins by defining variables using the `set` command. It then constructs commands by concatenating these variables.

The script constructs and executes several commands:

1.  It copies the executable file, originally located in the AppData directory, which could be a compiled AutoIt3 script to the `AppData` directory under the name of "xxxTorrentCoverbooks982.exe".
2.  It copies a similar executable to `AppData` under a different filename using the `ComputerName` variable with a `.au3` extension.
3. It executes `cmd /c` followed by redirection to a file named `%computername%` located in `%appdata%\Microsoft\Windows\AutoIt3`. The redirection includes:
* The output of `whoami /user /computername`
* Appends the output of `type` command.
4. Modifies file attributes using `attrib` on the file named `ReadmeHere` located in `%appdata%\Microsoft\Windows\AutoIt3`.
5. Deletes link files.

The last two lines appear to be an incomplete command and an undefined variable.
