What is your firewall ?
Does it allow avastSvc.exe internet access ?
- If it does delete the entry for it and try to collect your email again, this should force the firewall to ask permission again.
Whilst the above is related to the ability to collect email there may also be some form of application blocking in your firewall, which may stop it completely.
If the above doesn't have any affect, then a clean reinstall would be best:
