It wasn’t meant to insult you. But given I don’t have thr training of Twin, Essex and all of the removers here. I’m not in a position to be offering explantions.
As for the question about Avast! and paying for it. Avast! will never have a 100% detection ratio. I use Avast! and Comodo on my system. Again, won’t block everything.
To stop the scanning of the page go to the Avast! UI (Right click the Icon) > Open Avast! User Interface > Settings (The little gear) > Antivirus > Exclusions > URL tab > And enter the URL.
From where I see it, the Objects are attempting to launch the site. In malware terms the files could be calling home to install more viruses.
I can get Polonus to do a more indepth analysis if you would like. If after that and Twin everything is clean you can report it as a FP to Avast! and have it Whitelisted globally.
Edit: I have to go to bed. It’s nearing 11PM here.
