TorLock
You already know how difficult it is to discover trustworthy and secure software torrenting sites. This is why we advise using TorLock. This site, in contrast to others like it, actively checks the torrents its users submit for malicious software. That being said, while TorLock may not be the most popular torrent site right now, it is one that you should definitely check out.
We'd also like to point out that, design-wise, TorLock is very standard fare. This requires a manual search for the necessary software files, followed by a filtering process depending on your requirements. Thus, this file-search technique is quite ancient, but it is also really effective.
