Scan for viruses and malware

First you shouldn't be downloading torrents
Second if that is the only change then yes, it is most likely the cause of the slowdown. I would check for viruses after the download is complete. Also after the download is finished, shutdown you laptop so that it has time to recover from downloading a huge file. After you have waited a few hours then see if it happens. If it does scan for viruses.

After you have done this let me know what happens.
