JS/Trojan.iframe virus?

Hello,

I'm seen hits for the JS/Trojan.iframe virus only since last Wednesday or Thursday.  Have seen them associated with three different websites.  I suspect false positives.  Anyone else out there just started seeing these?  Was the virus definition modified last week?

Thanks

Eric

Specifically, it's identifying as JS/Trojan.iframe.esw.

I have seen some hits on this.  Not too many.  7 Unique Attacker IPs in the last 7 days.

Strange because all mine have started occurring only since the morning of 11/29.  But since I'm blocking, one of them is impacting legitimate website access and the site owner doesn't see anything wrong on their side.  As far as I can tell, there is no way to create a virus exception for just a single URL.

Re: JS/Trojan.iframe virus?

Thanks.  Good information.  However, in this case it appears to be false positive triggered by the following (imenu?) code.   No longer triggering after removal of this section.

I agree with the premise this may be a false positive.  It is far too common and started showing up for me on the 30th as well.  It is coming from benign sites that get traveled to frequently by our users, yet an enormous amount of effort into located the infection has not been fruitful.  We have found exactly nothing.

I'm seeing the same thing.
