Title: "Avast Free 6" can not open "Firefox 6" and "Internet Explorer 9"
Post by: Politic on August 18, 2011, 10:42:31 PM
I have installed avast! Free Antivirus 6 (6.0.1203) on my PC and on occasions not let me open Firefox Internet Explorer 6 and 9. To fix momemtaneamente disables and enables the shields of Avast. But the problem occurs again early in my PC. I use "PC Tools Firewall Plus ™ 7
Free", and my OS is Windows 7 professional 32-bit.

Please could help me solve the problem. Thank you very much.
We apologize for errors is my first post. My language is Spanish.

Well commonly this is something blocking avast's Web Shield, but what I can't get around is the "on occasions not let me open Firefox Internet Explorer 6 and 9." It shouldn't be intermittent problem, it should either work all of the time or none of the time if the Firewall were blocking the Web Shield.
Does the PC Tools Firewall allow avastSvc.exe internet access ?
- If it does delete the entry for it and reconnect to the internet, this should force the firewall to ask permission again.

Also "But the problem occurs again early in my PC." do you mean this happens early after starting your PC ?

If so I wonder if the PC Tools Firewall isn't running at that point and blocks all connections until it is established ?

I can tell you that there is a known problem with the PcTools Firewall on 64 bit Windows 7 if you are also using Avast. It was confirmed to me by a PC Tools moderator that there are conflicts with their firewall and the Web Shield of Avast on 64 bit systems. It may be the same for all versions of Windows 7. There are currently two ways to resolve the problem. One is to disable Avast's web shield and I would not recommend that at all. The second option is to move to a different firewall product. I was having a problem with rules never being created for some apps so I have taken that second option.

 The problem is in PC Tools and not in Avast. I had no major issues on XP. There was just a 30 second delay on first access of some apps using that OS. PC Tools is very buggy at this time.

The OP is using win7 32bit.

Though as you say may extend to all win7 OSes, I'm not a great fan of PC Tools firewall.

Politic welcome to Avast Forum.

I would disable PC Tools for a while, let Windows firewall take over, and see what happens. Dch48 might be right.

Suerte.

BTW the Spanish forum is here:

You will not have too many members with high degree of experience but at least is in Spanish and it is a start.
