ScanSafe Reliability/Expertness

Question

Of late, I've had some users complain that they cannot get to a specific site due to ScanSafe filtering the contents based on reasons such  HEUR:Trojan.Script.Generic, or Filter Avoidance.
In the case of the Heuristics denial, if I go to a linux box and perform a wget, I'll typically get an index.html file returned, and that HTML fle will contain references to a Flash or Shockwave object, and not much else.  If I submit the URL/index.html file to some place like Anubis, or elsewhere, I get no cause for alarm.
Granted I could just build an exception but part of me wants to tell somebody that perhaps they have code that needs to be looked at.  Problem is, I don't really know how much faith to put into ScanSafe.  For the most part, these are legitimate business sites.
I had one site that was refused, and when I investigated a bit, if I changed the http: wih https:. I was presented with an unsecured screed to install and configure an entire Drupal site.  I sent them a note via hostmaster, abuse, info, postmaster, etc, and it was promptly ignored.
The Filter avoidance case is from a content provider we use in Europe.  They build a site and give it a domain name. Granted privacy laws in Europe are more strict than laws in the US, and it seems to affect all of their domains, which end in .eu.  Since .eu is relatively new, could that be part of the issue?  I broached this topic with the content provider, and they stated that our sites were "just like any of their other sites", and they were not familiar with ScanCenter.
I'm tempted to simply remove the AnyConnect Web Security Module from all of my clients just to get rid of ScanSafe.
