I want all applications(except a few) blocked from connecting to internet.

Before avast was updated this was possible via win7 firewall since not every application connected via avastsvc.exe . But now after the avast update all applications that were blocked started connecting via avast.

Now I cannot block avast totally from connecting as that would block the allowed applications too.

Please release an update in avastsvc.exe that allows only a few said applications while blocking all others.

This is not possible yet. Maybe future versions of avast! 7 could have this feature.

Sounds like the win7 firewall is pathetic as it can't handle localhost proxies, e.g. it can't detect what is the parent application passing through the proxy.

Most 3rd party firewalls are able to detect what application is using the web shield proxy and act on that and not allow it through the proxy.

which firewall do you recommend that allows only a few applications via avast to connect while blocking all others? the firewall should be free for home personal use and should make the internet invisible to other applications.

Yes i tried. I tested it with ping.exe . It can see the internet even though it is not allowed by a windows firewall outbound rule.

Ping is usually allowed in any Windows FW. ;)

Some basic questions:
Which avast!..?? (Free/Pro/IS)
Which version..??
OS..?? (32/64 Bit - which SP)
Other security related software installed..??

what i mean is the problem with the https connections that stop working or work very slowly when avast intercepts them for scanning. Example is with a few online brokerage websites whose tickers/quotes disappear/freeze/delay when avast intercepts them while making an https connection.

These sites are mostly secure and trusted and mostly do not require scanning.
So i want that avast should stop scanning https connections that have a valid trusted certificate.

You can exclude them in the settings, if needed.
I may add that I've never had any slowdowns with any https connection(s).

no windows 7 firewall use to block pinging too since i had not created an outbound rule to allow it. that was before avast update.

Win 7 firewall is not that bad. Its very different from win xp firewall.With manually tweaked settings it gives essential security thats sufficient for home personal use.
