Hi Adam,

 

they are using McAffee Version 4.6.0.2292 with newest virus definition.

Does it happen to all browsers or one particular browser version?

How did you set UploadType Property?

Please disable the Flash, HTML5 and silverlight one by one and let me know how you can reproduce this. 

protected override void OnLoad(EventArgs e)
{
        uploader1.SetAdvancedOption(UploaderAdvancedOption.NoFlash, "true");
        base.OnLoad(e);
}
 

        uploader1.SetAdvancedOption(UploaderAdvancedOption.NoFlash, "true"); //disable flash
        uploader1.SetAdvancedOption(UploaderAdvancedOption.NoHtml5, "true"); //disable html5
        uploader1.SetAdvancedOption(UploaderAdvancedOption.NoSilverlight , "true"); //disable Silverlight
