i have problem with security in my index page.

hello there,

i have this site : www.supraveghere-securitate.ro

i was in the first place in google to this key word : " camere supraveghere" it means surveillance cameras.

a few days ago google put me in page 2 …

some costumers told me that i have some virus or something like that.

i call to my hosting provider and ask them to scan the server .

they told me that they find a virus name:" IFrame.html " in my index page

also they told me that i must find that error from my site and fix it .

can you help my with this.?

and please sorry for my bad english.

thank you.
