Apparently our hosting provider (ZestHost) was infected by a virus that affects all sites on the same (shared) server.
We have already contacted them and informed them of the details. We await their response and removal.
What you need to do:
1) If you do not have a realtime virus scanner, your PC may already be infected. We recommend using NOD32 (free 30 day trial) as a permanent solution.
2) If you do not have a local Antivirus solution, visit Trend Micro HouseCall, an excellent and free online virus scanner. Then proceed to get a more permanent solution as soon as possible.
3) Stick around, and hopefully we will have good news soon.
Disclaimer: We are not responsible for any damage to your PC. Please note however, that this issue is not due to any malicious coding on our behalf or any mistakes or lapses in security over which we had any control. This is one of those ‘once in a blue-moon’ incidents where a crappy webhost gets all its customers into trouble. We will switch hosts as soon as possible, because this is unacceptable.
