The only thing that worked for me was goto avast/settings/exclusions/urls... then add: http://www.icefilms.info
to the exclusions + click ok. That is how you may gain access back to icefilms. But whatever is alarming avast, I don't know if it's safe to do the above or not, as you have no protection from avast on icefilms as per the exclusion: It may be a false positive; but maybe not, maybe it's harmful. But hopefully it's all good, so long as I have the aggressive ads blocked...
I have the adds under control using the below:
Download scriptsafe for Chrome: goto scriptsafe options and set default mode to 'Allow' (make sure to save, read other options too, I can't remember if I changed something else or not). look at all the scripts loading on icefilms and choose 'deny' to stop individual scripts from loading (experiment to find the buggy ones). Any site that is having issues loading things because of things you disabled on icefilms ect, simply select allow and trust for whole domain (you may also have to hand pick out and allow back some things that you may be blocking by accident due to another site ect... ie. certain features on youtube not working ect, you may have blocked something important, just 'allow' it back). Make sure not to distrust because that could end up blocking a whole domain like google or something I suppose (but again, no problem, just 'allow' and or 'trust' it back), just experiment.
Icefilms users must have proper knowledge to use the site nowadays, vlc sucks for me so I have to manually open the download link in Daum Potplayer to watch, that is if the flash player is unavailable, use to be able to use Divx. It is even possible to open hugefiles link address in daum when it automatically starts downloading the file, by copying the link on the active downloads page in chrome, cancelling and opening link in daum (to do this with anyhost that gets to the icescript page, right click the download button and copy link address; open URL in daum, their buffer allows you to pause and still download the video unlike vlc). Also the ads just got real intrusive, solved by scriptsafe as stated above. But I really wouldn't recommend the site to anyone that can't get with it nowadays. Hopefully the above is correct info, in a rush. You still need to use Adblock Plus (or another adbocker) though.
I really should make a new/simple tutorial, maybe I will soon enough.
Anyways, if I remove icefilms from the url exclusion list; I cannot use the site atm due to avast not letting me (even after updating avast).
