Don't know what's worse: People who use an outdated version and insecure or the latest version of uTorrent. They're both rotten.
What do you mean with insecure?
It's not a antivirus that we are talking about... ..if it downloads torrents well and is not full of bloatware, then it does all it should. No need to fix what is not broken, and v2.1.1 afaik is not.
