Your
website hosting is infected
Have a look at the source of your index.htm page
you will see a hidden iframe pointing to mortimercomprehensive
that is causing the problem - it is trying to d/load malware
see my thread in the resellers support forum
Malware Links on Server
ALL accounts on that server have been compromised in a similar way. EUK have partially solved the problem - but are taking a very relaxed attitude to fixing it properly. My opinion of them is decending rapidly
