Hacked Vu launching malware attacks?

[irishpol1]

Not sure where to post this..

I've received an email from my ISP telling me that there's a device on my network attacking other machines.. they think I have some form of malware somewhere on my network.

I'm fairly sure its not my PC, iPad or phone, I've been able to discount them using the log times provided by the ISP, they were either switched off or off site at the time(s). Is it possible that my Vu could be hacked and it's being used?

Thanks
