Harmless site is marked as malicious

Viruses and worms

Hi

First of all don’t know if this is the correct place, if not, please drive me to the right place.

Heres the problem, this site, gusanito.com is being marked as a malicious site but it isn’t, you can take a look over these links to be sure:

http://www.google.com/safebrowsing/diagnostic?site=www.gusanito.com
http://hosts-file.net/?s=gusanito.com&x=24&y=10
http://www.avgthreatlabs.com/sitereports/domain/?domain=http%3A%2F%2Fwww.gusanito.com&check=
http://linkscanner.explabs.com/linkscanner/checksite.aspx?NS=ChkOnly&SRC=apps.explabs.com&CS=http://www.gusanito.com

All sites above mark the site as a safe site, the “virus”, that avast marked as a malicious site is an add campaign that uses javascript command document.write, see http://cl.ly/d45d0adf2932c70b5de7

Thanks in advance,

Hi Xochoa,

Welcome to avast forum,

Your referenced site is safe :

http://scanner2.novirusthanks.org/analysis/41af588f6ecb0d8530d7f1dc6d0a6833/ZXNw/
http://www.virustotal.com/url-scan/report.html?id=192400f1071c3eb3e601e8b618248b4f-1288421126

And avast also not detect any harmful script or malicious software inside there.

cheers,

Avast is alerting (firefox 3.6.12), see image1 and it is because it is loading a large obfuscated/compressed file (see image2 small extract of file content), this is what is being called script injection I believe.

Whilst this is effectively only avast detecting this, http://www.virustotal.com/file-scan/report.html?id=d7dbe9a390bfe1f4f7448645597a90cd32bcd4c64e00b731c3d5ca8dcdee2b4a-1288965942, the question has to be why is this compressed obfuscated script being loaded.
