Post by: freak777 on March 05, 2013, 07:22:15 PM
got error 730 when i try to connected.the only way to reactivate my internet connection is reinstalling Avast 8 IS.i've tried everything,create new connection etc,but the problem is present.i resolved with Acronis True Image to a previous configuration with another AV.any solution for disinstallation without this type of problem?i'm using Windows 8 Pro x64.

tutto bene,amico,tranne Avast  :D (I replied in Italian)

but if after uninstalling avast there is no trace of the driver firewall how can i do?
there is a moderator or developer who can answer me?it is possible that there is no way to restore internet connection after uninstalling avast?

not yet.maybe i can try the next time.i'm very upset with this product,now.i have tried many AV,but only this have a difficult uninstalling procedure and completely messed up internet connection.perhaps the developers should fix these bugs

I gave one last chance to Avast.i have uninstalled from safe mode with avast uninstaller. but still error 720, no connection.
but the amazing thing is the absence of a response from the moderators and engineers about it.
why this lack of replies?

it is possible that no moderators can tells me what can i do about this situation?you realize that if I had not had previous Acronis disk image with another antivirus installed I had to format because of Avast?

someone answer me this time or not?

i have Windows 8 Pro x64.
you don't believe me?try yourself!unistall,reboot and try to connect.incredible,if I had not had a previous Acronis disk image with another antivirus installed,my pc would be useless, and I had to format!technicians?please,fix this bug with a new build!!!

I believe you.  What is your firewall? When avast! Internet security is installed it disables your current firewall and activates the avast firewall. Check your firewall settings. Using any VPN?

i'm not a newbie ;)
i know this things!
if i installed an IS,it is obvious that i've disabled windows firewall.i haven't any other firewall installed.
the question is simple: if you uninstall avast 8 IS no more connection possibilities, at least on Windows 8.have you tried too? I find it strange that no developer has said, or began working on the bug

Yes, i have uninstalled avast! about 15-20 days before (on windows 7) to try bitdefender free but it lacks of settings( in fact no settings at all) but i haven't got any problems. Have you contacted avast support(http://support.avast.com/index.php?languageid=1&group=eng&_m=tickets&_a=submit (http://support.avast.com/index.php?languageid=1&group=eng&_m=tickets&_a=submit)) ?
Any VPN software?

i haven't VPN.
the problem went when disinstall INTERNET SECURITY 8,not ANTIVIRUS.have you tried to unistall Avast IS 8?
I do not know if on windows 7 there is no problem when uninstalling Avast IS 8, but on windows 8 yes. i have Windows 8
why i need to uninstall?simple,i want to try several IS in trial mode,after,i can choose the best one for me.
a question for you, but does not it seem strange that after 3 pages of this topic, no developer talking about? yet it is a serious problem!

still possible that there is not yet an update to fix the problem? If any of you uninstall AIS by Windows 8 will be found without an internet connection!try if you not believe me.
avast is a great AV, but you can find yourself without an internet connection when you uninstall it from Windows 8!this is unaccettable!

when uninstalling avast IS the PC no longer connects to the internet! each method suggested for complete uninstalling is ineffective! you can save if you use a disk image!
i have windows 8,and with W8 it happens!i have resolved with Acronis True image disk backup with another antivirus installed!but this is a serious matter, and no one answers or trying to solve the problem?i love Avast capacity to remove malwares,but this thing makes it unusable!please,makes another build that solve this BIG problem!

Howdy freak777,

You still have your local settings, go to your main router/modem and restore that connection out. Maybe the modem router has lost it's internal settings.
So just launch the browser and go to your local modem address (192.168.1.254 or 10.0.0.138 for instance) and follow instructions there...
Other possibilties for connecting out: http://geejay.wordpress.com/2007/12/06/adsl-modems-and-routers-ip-adress-username-passwords-for-major-manufacturers/

edit: i don't have Alice Gate 2 Plus Wi-Fi,but only Alice Gate 2 Plus

it seems normal that you can not uninstall AIS without losing internet connection?
is a huge problem that engineers should solve! i don't have this problem with any other suites.i like AIS,but it's impossible to remove without losing internet connection!

You must be able to re-connect via a PPPoE connection via your network connection manager.
A step by step procedure is being described here: http://windows.microsoft.com/en-us/windows-xp/help/networking/manage-network-connections

Enable a network connection. To enable a previously disabled network connection, right-click the network connection, and then click Enable.

thanks for the help, but I refuse to implement this procedure, also because I'm sure that will not work.The absurd thing is that Avast destroys the connection when you uninstall it, and no other security suite do that on my PC.i've tried all suites in trial mode,and when uninstalled them,my internet connection always works.this is  a problem that Avast has a duty to solve,for your customers.
