This web page tells me avast www.pittiesisi.it/ contains a virus that seems strange to me is true, thanks for any reply you make a search with google and sissi pitti already indicates how the virus ???
Generally, avast detection is accurate in these cases.
Isn’t it an encrypted/obfuscated script or iframe?
Wasn’t the site hacked? There are a lot of them nowadays…
Maybe you could contact its webmaster.
I tried to check this out and there seems to be a suspect script, it seems to be an obfuscated script within a script tag. Whilst trying to view the temporary file avast creates to scan the file windows explorer locked.
I have managed to download the page and uploaded it to virustotal and avast isn’t alone in its suspicions, http://www.virustotal.com/analisis/6efcae4069d0836d8951551f4b087930.
Whilst these results don’t show a lot of detections, this type of attack is not widely covered by many AV scanners and avast is on top of the game in this regard.
