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.
dude , look in u r wireless properties, u prolly have avast firewall driver still checked . Unchek, uninstall
i not use wireless connection.i have wired modem.what can i do?please,explain me.tell me the exact procedure.step by step.sorry for my bad english
look in u r network driver under device manger. Pull it up, highlight, right click, properties…uncheck any Avast thing u find.if u need more help pm me
do you have a Windows “restore point” handy dated from before Avast install ? that woul probably solve the issue
no need to restore man, i have been through the same issue
i don’t need a restore point.i have Acronis True Image with previous image restore.i want to know HOW can unistall Avast 8 without lose internet connection.
Avast developers should resolve this annoying bug
Freak, did you verify the properties of your network driver???
can you explain me step by step if i can verify?i don’t have,at moment,installed Avast 8.but you tells me how i can verify,for further installation.
how did you solve it?
windows +X
Go TO DEVICE MANAGER
Find NETWORK ADAPTER
Find u r modem or ethernet driver
Look under properties
Find if avast firwall is checked and still there
Uncheck
Uninstall that thing
Done
Back surfing
when unistalled Avast the next time,i try,hbang.and if the avast firewall missing under “properties”? there is another procedure to follow?thanks!
u dont need to reinstall with acronis to get back on the net. I too installed avast 8; uninstalled and didnt have any internet. I discovered avast left firewall driver. So i just uncheked it, uninstalled it, and i was back on
i’m italian,here is the properties of my ethernet device.where i can check if the avast internet firewall remnant location ?the location of avast driver?how can i check?please,can you post a screenshot?
click on your connection bottom right,open network and sharing ,then change adapter settings, and u ll find image i attach below
ok,thanks! 
I made another test,today.reinstalled Avast 8 IS, then I uninstalled it, and of course, error 720, can not connect,no internet connection.open network and sharing,and no voice remnant concerned Avast firewall to unchek or uninstall.other solutions? otherwise I give up, and I forget to avast
come va Amigo, sorry to hear, wait for some updates my friend, all is good.
tutto bene,amico,tranne Avast 
(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?
