Phew, we got lock at work today, a CryptoLock virus tried to do it's business on our network, it managed to copy a load of suspect files to our main fileserver but only got that far before our antivirus stopped it.
I've spent most of the day chasing it but it's mostly been contained now, just got to do a scan on the server overnight.
To the people that create this type of malware - may your anuses be infested with a thousand fleas for all of eternity, your place amongst humanity is not required, please go and die a horrible painful death somewhere that doesn't inconvenience anyone else.
