I thought it had gone, but alas, I just got another warning from my a/v (Avast pro).
Seems to identify it as WIN32 Trojano ...
My a/v catches it and terminates connection before there's any consequence.
This only happened for the first time on Friday I think.
Has never happened before, so I cant imagine, as previously mentioned by someone, that it's Invision, unless SAU has just changed their system over.
Also, had no old cache, i clean it almost daily, and IE is set to load new page everytime (no caching).
Anyways, not a big deal on my end, but perhaps might be helpful to track down the issue.
