yea, right...

I let an online virusscanner running through the rar:

so, is this trustworthy?

a general question, can things like cryptocoins be scam or dangerous (obviously if the source is malicious, but I mean otherwise)?

edit: and how can Bosscoins be mined? what settings do I need for cgminer?

I think for Bitcoin mining you are too late. However, I think the price will continue to rise, after a short drop some time soon to a about 500$. But, I also think that Bitcoin will fail within the next 2 years and if you start to get in now, the key is to get out soon enough. I think there are a multitude of reasons why it will fail, be it that it will continue to be a pirate-currency, or that smart bankers will get upset because they did not see the opportunity to make a lot of money and start to destroy the Bitcoin, etc. basically, they see Bitcoins as a punk attempt to outsmart *their* world, and they don't like to get beaten up by some underground punks. Some Cryptocurrency will survive sooner or later, but Bitcoin has the bad luck that it was one of the first and is the most famous.

So, get in when the price has dropped, but get out before the price drops much more. Or try to get into other cryptocurrencies, as they might stand better chances
