HELP!

Dear AVAST - antivirus administrator!
Pleas help us with the following problem!
We have a very important web page regarding to a regional touristic supply, owned by our touristic association (SOVIDEK - HEGYALJA TURISTIKAI EGYESULETE) from Romania, Harghita County. Our problem is that the web page http://www.turist-cazare.ro/ is not working at all from about 4 month. When we try to acces the web page a strange message is showing up. The AVAST - antivirus is detecting some strange an suspicious file. We tried to check a several times to lock up for a strange files in the webpage system, but we did not find any of them.
As we told the web page is a very important for the area and for tourists. Please, if we can ask to check our web page and if you can do anything to make it work it will be vary helpful for us.

Sincerely our leading stuff from Praid, Harghita County, Romania.
Administrator: Moldovan Laszlo-Tivadar.
