Its not that bad, but it is the same as any torrent site.
If you want to be very safe, stay away from anything uploaded in the last week. Torrents are somewhat self-vetting in that files with viruses get removed (at least in theory). At the very least, there will be comments warning about malware. Also, files with more seeders are generally better...again because it generally shows that more people trust the file and uploader.
Lastly, false positives are a thing. Depending on what software you use its not uncommon that porn gets flagged as having viruses when its actually just fine.
