Yes, it can.
No. but the downloads on it cause viruses not the website/torrent
Yes.
I'm not sure of bitdefenders. A bit torrent is a file that has been compressed into a very small amount, and you need a bit torrent to download and open the file. There are many situations where viruses can come along with the bit you download.
Download from torrent sites with a program like U torrent. but usually it contains viruses
No oovoo can not cause viruses.
NEVER trust software you download. For example, a downloaded bittorent client added a toolbar i EXPLICITLY asked not to have AND required a system restore to eliminate it. (the clue was that the download of a torrent i HAD NOT REQUESTED was proceeding while i could NOT google). NEVER trust software you download. (NOTE: the original answer said something along the lines of "bittorrent client ok, but you can get a virus from things you download".... why did you trust the original bittorrent client download?)
The Kickass Torrents website (I'm assuming you meant that) itself does not give viruses, in fact, it's one of the safest torrent websites. What can give you a virus is something downloaded from Kickass Torrents. To prevent this, always make sure you check the ratings and comments of the torrent.
Parasites can carry and transmit viruses, but they do not "cause" them.
i think that is released but there are many sites that they tell you to download it but the torrent is full of bugs viruses and worms.
Some can cause cancer. They are called oncogenic viruses.
While most viruses co-exist harmlessly in their host and cause no signs or symptoms of disease, many of the viruses do cause fever.
No, Clubpenguin is a safe site run by Disney that does not cause viruses.
