The problem is remote content can be changed in seconds, so you never realise what the payload might be.
We can't answer that, avast is essentially seeing a script which it believes have been inserted into that page and one that goes to a site which it considers malicious. We certainly can't give any assurance that it is not a security concern.
Only the webmaster of the Saturn car forum can say it that script is legit, e.g. he put it there.
Got you.
I guess this is now a problem for the forum's administrator, and unless someone else has more insight, I would consider the thread closed.
Thank you all for your help.
