Daily outages

For the past three days, my service has been interrupted and I have had to re-boot my modem.  The modem is a Cisco DPC3010 that is about 3 years old and was installed by a Cox serviceman.  Is there a need for a firmware update across the community or some other fix due to the recent Cisco advisory about a hacker exploit.

I did a full scan on my PC and did not detect a virus.
