Virus warning on website

[Treasurer]

I've a website (ie created by me) that avast is telling me has a trojan horse (HTML:IFrame-IF [trj] is what it's saying).  Other anti virus programs don't seem to register any problems.  Anyone know  how I can go about fixing this or finding the problem???

Thanks!

Whats the address of the site?
Have you checked the source code of the site on the server?
Server may have been hacked.
Remember before that a server where I had alot of sites hosted was hacked and the homepage of all my sites was replaced.

i'd say the server the website is being hosted on has a virus. this happened someone i know last year (the virus was a nasty bugger) and the ISP had to move all the websites onto a different server to solve the problem.
