Hello -
It's quite possible the machine is infected with something which blocks updates to AV servers.
You can manually update Avast here, though it's also an Avast page, you can use another machine to download the file, and transfer it to the affected machine.

It's also possible there's a proxy set up, preventing access.
*In IE: Tools Menu -> Internet Options -> Connections Tab ->Lan Settings > uncheck "use a proxy server" or reconfigure the Proxy server again in case you have set it previously.
In Firefox in Tools Menu -> Options... -> Advanced Tab -> Network Tab -> "Settings" under Connection and uncheck the proxyserver, set it to No Proxy.
If you think the machine is infected...for more detailed assistance...
Please follow our pre-posting process outlined here:
