    Hi,
    Couple of out customers using Avast antivirus are reporting Trojan detected they are unable to use the site properly because of this.
    We are using  version 2011.3.1115.40

    I used following service(http://virusscan.jotti.org/en) to scan txt file with the js inside and "avast" and "g data" reported
    JS:Blacole-AV
    in the js content

    I can send you the suspected js if needed.

    Hope this is only false alert since only these two AV products report problems found?

    Requesting help on this topic as well, many websites in production and I can confirm that Avast! is most likely having a false positive on the JS file with JS:Blacole-AV.

    I confirm the issue shows up when an editor is on the page. Havn't checked yet with other controls, but I'll try to provide as much information as possible.

    Hi we are having the same issue. I don't know which version we are using yet however I am on the phone with Telerik support and they are aware of the situation and expect this to be resolved in 24 hours.

    Reproduced the issue with 2012.1.215.40 and latter, havn't tested with previous version though. And yes, I'm pretty sure Telerik will come up with a quick solution, as usual.

    Also, check out this thread on Avast forum: http://forum.avast.com/index.php?topic=104155.0

    Hi,

    We are investigating the issue now and will give you more information later on.
    Our current tests show that if the Scripts/Skins are loaded through the CDN everything is ok which means that the scripts themselves are not harmful and probably the antivirus program report is false positive.

    Kind regards,
