Not a virus though, a worm...
People are able to use it to XSS attack, basically post some javascript on twitter.com 1 that will be executed. Mostly this javascript is then making you post another tweet without realising it, passing on the original code. This is a neat twitter worm, not actually a virus. Some of the javascript may redirect you to sites that do try to infect your computer. Look out!
