Skype trojan forces Bitcoin mining, security firm warns
A trojan that can hijack a computer and force it into mining for Bitcoins - the virtual currency - has been spreading via Skype.
Antivirus firm Kaspersky Labs said attackers sent messages in various languages translating to "this my favourite picture of you".
The message included a malicious link which was, at its peak, being accessed more than 2,000 times every hour. The value of Bitcoin has grown massively in recent weeks. At the time of writing, Bitcoin exchange website Mt Gox has the currency listed as being worth $186 (£121).
