I can see many hits with disqus[.]com domain and JS:ScriptPE-inf detection in our statistics. Many were caused by us blocking animehaven[.]to, which we have unblocked around 6 hours ago, but many are caused by loading resources from apparently malicious sites (for example gmil[.]com). I cannot say which cause your case was (without inquiring additional details), but you should soon find out - if it was caused by animehaven, you shouldn't be getting any more alerts.
