g4 mac os9 torrents ? downloads ?

[derick longthought the 5t]

hello
i have a g4 mac that i have resently conected to the internet as my pc is infected with a virus.
i have only ever used it for recording music , but now id like to use it for internet and stuff. so i wonderd if any one could recomend any links or sites to some how upgrade it?
its on os9 - id like to put os10 on but carnt find any way of doing so .
iv managed to get icab browser, but downloads just come out as pages of gibberish like this- rthrjrhhrrhjnhoirnbjgbhb/////gb/bg//gb//gb// - wich isnt any help.
i had thought i would be abble to download torrents of stuff like on a pc but im getting the impression thats not possible on os9..?
anyway if any one could advise me on improving its functionality in any way id be gratefull of there advice.
thanks
