Can't update antivirus signatures

all attempts to update sigs fail. I can ping it fine, but also get a HTTP 404.

Any ideas?

I have the same problem - I see there has been a rush to answer this problem.

As this is very little information about what the error is have you read the FAQ about Update freeze at 30% ?

And if that doesn’t help can you please post more information about the error maybe a screenshot etc…
that will help us in better understanding the problems your having…

Also let us know what version of CIS you are using. When using 3.9 or older please update to the latest version.
