Post after post is appearing here now with people saying they are unable to update the virus database, or are failing at a certain percentage.
The issue of failing at a certain percentage is caused by a combination of two factors - 1) The Comodo updater displays percentages in a bizarre manner and does not accurately communicate what is happening during the update process and 2) users expect the percentage counter in the updater to act in a more regular manner.
The updater in CIS 3.13 jumps quickly to 30% and then appears to be stuck. It isn't really stuck but it is in the process of integrating the first part of the update into the existing database. This can be verified by using Task Manager or similar and monitoring disk writes. This process can take a handful of minutes and this is where point 2 comes into play (users expectation of linearity).
The updater and its progress meter in CIS 4 (currently in private beta) is far more accurate and displays the total size of the download and the precentage currently downloaded and integrated.
With all due respect, if the best support advice you can offer is "the updaters work here" then perhaps we are all better off switching to another product.
This is purely your decision. We should all find a security solution we are happy with and works well within the confines of our environment. If that's Comodo, then great. If it's someone else's software - equally great.
