Detected virus on Pleasuredome torrents are false positives or genuine but harmless virus.

Checking
Submitting the file to https://www.virustotal.com/ helps verify if it really is infected with a virus. If most scanners detect nothing, it's probably a false positive.

"Force recheck" the torrent to detect if the file was modified after it was downloaded. Another possibility is using a ROM Manager. If a file was modified after it was downloaded, your computer must be infected.

Antivirus
It's recommended to always have one antivirus installed and updated.

Windows' built-in antivirus "Windows Defender" deletes files detected with virus automatically, which can do bittorrent clients download more than necessary. Folders can be added as exceptions.

qBittorrent can give I/O Error when antivirus software scan files while downloading.
