Trojan Horse JS:Blacole-AV

[Jelle]

Hi,

Our customer gets a message from their anti-virus program when they visiting our website with Telerik controls. More information below: 
Program: Avast
Malware name: JS:Blacole-AV
Type: Trojan Horse
From: Telerik.Web.Ui.Webresource.axd

I hope this is a false postive?
What should we do?

Kind regards,

Jelle

REPOST: 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.

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.

All the best,

Hi,

Quick follow up: It seems that the problem due to an issue in the antivirus program virus definition. However this is is already fixed:

So if you can update your virus systems and klet us know if everything is ok would be great.
