Hi kamivh1,

Make that site non-click-through like with hxtp://etc.
See the sucuri scan report, site is full of various javascript malware.
Do not exclude site, but inform the admin of that site it has been fallen to malcode,
it has to be cleansed, may have been hacked via: -index.php
(now empty)

No other AV report it...yet. Someone has to be the first one....
avast is very often the fist one on these web infections, this is a avast speciality and very often correct


I have uploaded it to some other AV for analysis, i will post the result here when i recive it


Every 3.6 seconds a website is infected

With all due respect to many of these other scanners, they aren't in the same league at detecting hacked/infected sites as avast's Web Shield. When their are multiple detections by the web shield, then the communityIQ feature of avast transmits this information and then the Network Shield would block the site.

The Sucuri scanner does a much more in depth and detailed scan than these other tools also.

If I bypass the network shield, then I get an alert by the Web Shield, image1. Analysing the file that the web shield shows it is an obfuscated zip, image2 extract of the content.

Why this file is loaded by the index.php (and more importantly what it does, I don't know) is strange, but since there are other areas mentioned by the sucuri scan it certainly looks like the site has been hacked. So the most likely area are the PHP templates as it is possibly the PHP content management software that has been exploited (if it is out of date).

The problem is we can't check anything on the hxtp://asrema1.co.cc site as it is blocked and that is based around the information already given.

Please 'modify' your post change the URL from http to hXXp or www to wXw (as I have in the quoted text), to break the link and avoid accidental exposure to suspect sites, thanks.

I have visited your first link and I get no alert on that topic, so what exactly is the problem with the vBulletin link ?
You can post an image of the avast alert.

That image resizer isn't the problem on the hxxp://asrema1.co.cc site as that file doesn't feature in any of the alerts/suspicious files on the securi list, but there are some other vbuletin scripts that are considered suspect.

There really are too many other things too ignore.

Larger image of the securi results.

The securi site also shows that your versions of PHP and vbulletin are out of date and vulnerable to exploit, as I mentioned earlier you have to ensure that your content management software (CMS) is fully up to date. This is frequently the reason how sites are hacked but exploiting vulnerabilities in out of date CMS.

Whilst this is good news for you, is is just a first step as the web shield is likely to alert as it did for me when I bypassed the network shield (in one of my early posts). The web admin for the site needs to address the old versions of PHP and vbulletin to avoid possible further exploit.

But what has already been detected in my http://forum.avast.com/index.php?topic=79477.msg653639#msg653639 (http://forum.avast.com/index.php?topic=79477.msg653639#msg653639) certainly needs to be investigated and resolved, e.g. why is this obfuscated file being loaded in the index.php file. I don't know why that can only be investigated by the web admin.

Hi DavidR,

Even when I try to go to that site here: -http://wave.webaim.org/report?url=http%3A%2F%2Fasrema1.co.cc&js=1  I get avast Webshield blocking this as HTML:RedirBA-inf[Trj] and will get disconnected. And then it could eventually be unblocked later, see for a similar case: http://forum.avast.com/index.php?topic=45786.0
The posters in this site really have to inform the site admin of that site to solve the issues there, cleanse, update his web applications, etc. They should mail to supportATturnkeyinternet.net and refer to this thread,
