This page shows the last time definitions were pushed out to CIS. Was this the last time yours was updated? Note that this is in GMT, thus conversion may be necessary.
I ask because I know that recently Comodo has been improving certain things on the backend, which have caused periods where new updates were not released, and I want to figure out if it is this which you are experiencing, or an issue with CIS.
Mine did update this morning but it must have been a tiny update as it was done in seconds. We need someone from comodo to explain what’s going on, and if the cloud is down too, because if the cloud’s down as well I’ll have to temporarily install a different av because comodo’s av wont be offering any protection. Sure we still have hips and sandbox but there’s still a need for a functional av.
