Yesterday I asked a question about the litric equality of a barrel of oil,I was reffered by a so called user

Sorry to hear that.

I don't think that Yahoo Answers! is responsible, considering that it is an open site. There's no way of doing background checks. If they were, they would also have to be responsible for the waste of space taken up by unclear, irrelevant, malicious, insulting, degrading...etc. questions and answers. You might enter your concern on the Forum.

Best you can do right now is to run your A/V and spy ware. If you have a good one, it should have caught that in real time and allowed you to abort the connection without allowing the virii. But in any case take a good look at cotojo's answer.

Whenever I'm unsure of a site, I type it into Google search. Many times there will be a note, "This site may harm your computer", but not always.

Good luck,
