try in terminal:

host files.avast.com
nslookup files.avast.com
dig files.avast.com

... to check where's the problem in your system resolver. tcpdump, sniffing for UDP packets at the port 53 (maybe your server doesn'r respond).

I have no understanding what you're telling me to do.

I have no understanding what you're telling me to do.

opening application/utilities/terminal.app, and typing those commands. it's not avast fault, as it seems, but bad connectivity or DNS settings. those commands will help you diagnose the DNS problem.

I think Zilog right,

I do use terminal to update avast using command line, its more convenience

I got the results.  What am I supposed to do with them?  They're meaningless to me.


You update Avast manually?  How exactly do I do that?

What is your system (specifically)?

I use command line:

avast-update

I just tried that and it works.

Sometimes I also to shut down the Firewall (not the router) and that'll solve many problems.

Thanks for the help.

You are welcome,

If that command line works for you, there should be another commands that could be effective as super user/admin:

To scan all local drives (but not other partition(s) that not belong to the system):

avast

Scan the file or all files in a directory as specified by <path> for viruses with no automatic action upon finding any infections.

avast <path>

Scan the file or all files in a directory as specified by <path> and if an infection or infections are found, avast! will automatically delete the infected files.

avast --continue 1 <path>

To scans only the a directory's content and not any sub-directories inside of it, use

avast -d <directory>

,

I took this command from: http://en.opensuse.org/Using_Avast_Anti_Virus
