hi need some help,

i downloaded an avast home edition a couple of days ago but when i finally installed it i have encountered several problems like:

  1. cant update it together with other softwares.
  2. i can only connect to the internet if i stop all the protections provided by the antivirus

my os is windows home edition.

Have (or did) you another AV installed in this system, if so what was it and how did you get rid of it ?

What is your firewall ?
Does it allow ashWebSv.exe and avast.setup internet access ?

  • If it does delete the entry for them and reconnect to the internet and do a manual update, this will force the firewall to ask permission again.

Terminating the Web Shield should allow connection if it is ashWebSv.exe being blocked, which is preferable to going totally unprotected. The best solution is to ensure your firewall isn’t blocking avast.

  1. Remove NAV or Norton 360 through Add/Remove programs from Control Panel. Boot.
  2. Use Norton Removal Tool for Windows 2000/XP/Vista or Norton Removal Tool for Windows 98/Me. Boot.
  3. Install avast! (or repair the installation) and boot.

The Norton Removal Tool uninstalls all Norton 2008/2007/2006/2005/2004/2003 products and Norton 360 from your computer.

OK, but the question was what is your firewall ?
Though from your comment “avast is under the exemption box” I suspect that you are using the windows firewall. So is your OS XP or Vista Home version ?

There was a proviso, if permission was granted to the avast processes by the firewall to delete the entries and force the firewall to ask permission again.

Yes Norton is one of the AVs most likely to cause conflict with a new security application. Their add remove uninstall function has caused major issues as many forum topics attest.

Glad that you have got rid of the remnants and everything is working OK.
