This rarely happens with popular torrents. As soon as people find out it is infected, they delete it from their computer. Eventually no one will seed that torrent and it is removed from existence.

This is the same as other P2P networks which are 'self cleansing'; I think one of Madonna's new releases was faked and made available on a P2P network. The record studios had replaced the song with an anti piracy message. It started to spread out, but once people realised what it was, they stopped sharing it, removing it from the system.

A super seed's purpose is to seed a torrent to maturity in the shortest possible time with as little upload as absolutely necessary. This is critical for those who have bandwidth limits imposed by their ISPs. The super seed protocol was thought up and introduced into bittorrent clients by theShadow (www.degreez.net) maker of bitTornado, until recently my favorite client.

How super seeding works

When leechers start arriving in a new torrent swarm, the super seed sends a unique block of data to each leecher and then waits until it sees that block of data duplicated on at least one other client before it sends a second block. It never is supposed to send the same block twice. So, if you have a very fast client connected to the seed, it will quickly disperse what it receives to others in the swarm and soon it is in the lead. The faster a client uploads data that it receives from the super seed, the faster the super seeds feeds it and the faster that client will complete the download. Unfortunately, many, many people are on slow connections, or worse, purposely throttle back their upload speeds because they are afraid of squelching their own download capability, That is another area where people have no clue.

Most people think that they need to limit their upload capability severely or else they won't be able to download very fast at the same time. This myth was brought to life by carelessly written bittorrent help files in the early days of the protocol and is wreaking havoc with today's leechers.
It has to do with how any internet client sends and receives data. In order to download, a client needs to send "hand shaking" data to the other client saying something like: "Hi dude, I am here, send me your stuff," whereupon the "dude" on the other side responds with: "Oh, ok then, here you go." After that acknowledgment the data follows. This happens for every data packet and that is where one needs to have some spare capacity when uploading torrents. If you use 100% of your uploading capacity to seed torrents, you would indeed squelch those outgoing datagrams to clients from whom you are downloading and that slowdown would impact your downloads. So, reducing the upload capacity to 90% is all you have to do. 10% spare capacity is all that is needed to restore your own downloads to full-speed. But most morons don't know that and so limit their uploads to just a few KB/sec and again effectively cripple the torrent doing so. So the three ways in which torrents get reduced to trickles are:
1. slow initial downloaders. These folks should wait until a torrent is mature.
2. Super Seeds while there are more than one seed active in the swarm.
3. Squelched upload capability.

In all then, bittorrent is a superb protocol and Bram Cohen, its inventor, was being a true visionary when he dreamt it up. Too bad that there are so many nitwits using it and killing its effectiveness through ignorance or wilful sabotage for selfish reasons.
