I see you have not ever try admuncher+avast, try and you'll see what i'm talking about.
If I don't add ad muncher avast web ini avast web shield won't work and i've f***ing tested that by myself.
So tell me is there anyway use ad muncher and web shield together for not adding admuncher in web ini?
Although you may not like me to post in your thread, at least, I may be able to clarify your question. However, as for the answer, sorry but I don't have it.
A short answer. Sorry, I cannot help you.
A long answer. In conclusion, I cannot help you about this but, I think I began to understand your question.
I tested on Eicar test file site and, yes, it appears that eicar.com can be saved if I configure Web Shield to look out the traffics of Ad Muncher. However, please try to execute it. You see the file is broken. So, at least Web Shield seems to be doing its job.
That said, you'd like Web Shield to totally block the file in the first place. So, you probably thought that, if you can let Web Shield look out for the traffic of your browsers, instead of Ad Muncher, it may be able to prevent the file from being downloaded. Personally, I don't think so since Ad Muncher is nearer to the web site since it tries to check the site for ads before your browsers. Since Web Shield is checking its traffics, it is quicker than both Ad Muncher and your web browser.
Then, you may ask. Well, you'd like to do it in any way. Unfortunately, there is a technical problem. As I monitor it, Ad Muncher seems to occupy various ports as a local proxy and it is almost impossible to make Web Shield to watch out for the traffic between your browsers and Ad Muncher. So, sorry, I don't have an idea to realize what you seem to want to do. The bright side of this issue is that eicar.com is just an empty file. If you don't believe it, please check the property of it, you will see it has got 0 byte(!) .
