updates

whenever avast tries to update itself i get a 403 error. I have a good connection to the internet and any other http traffic is successful. I am behind an ISA 2000 firewall if that makes any difference.

Any help would be appreciated.

Thanks,
Evan

Welcome to forums…

Can avast.setup (a temporary file created while avast is being updated) allowed to connect the internet?

Do you use a proxy filter?
If not, make sure your browser is not set to “Work Offline” (this option is generally in the File menu). If it doesn’t help, try switching the proxy settings from “Auto-detect” to “No proxy” (I’m assuming you’re not connecting to the Internet via proxy).

Left click the avast icon > Settings
Update (Basic) > Details > Proxy
